Hey Craig.. from past experience with GM, Ford, and other EFI systems, I've always found that the TPS needs to have a certain amount of 'preload' on the rheostat in order to work properly from idle to WOT. On GM, back when the TPS was actually somewhat adjustable, you could read the voltage off the third leg, and it was usually set around .52 vdc (on a 5 vdc scale, with 5 vdc being WOT). If the TPS is all the way relaxed (0.00 vdc), the computer doesn't have a reference voltage to determine idle speed, and the timing, and the idle air control (IAC) will be all over the place. That is at least part of the reason the idle dropped down when you turned the TPS with a screwdriver! Hope this helps.😉
@The_Bearded_Mechanic Hey Craig, that idle building up sounds similar to a problem I had lately. Made me nuts... no air leak anywhere. Solution was, that the exaust-valve had no play at all and didn't close properly when the engine was warm. When starting up, everything went normal, due to the valve beeing cold. After a few minutes the proplem appears. You WILL make this run! Greetings from Germany
32:20 could the weak fuel pump when wired correctly be caused by only getting 12v at low amperage by the signal wire and NOT direct power from the battery? I had that issue once before when building my cnc machine. Not enough amps to the laser, it was drawing ALL the electricity through the PWM signal from the computer. Oh, and it fried that circuit on my breakout board. My laser had 2 power sources: 12V 3A AND PWM from the computer. That's an issue with controlling ground not source. When you turn off or on ground, that means you cut off all source where you want to have 2 sources: 1 with enough amperage to power the motor correctly and 1 low amperage to tell a relay to go on and or off.
No, on the TV shows. We're watching on RU-vid for a reason. More detail and no manufactured drama. All the RU-vidrs that got TV shows end up with a sub-par product.
The fact that this guy A - actually mapped out a diagram when he designed the system, and B - still had the file to give you 9 years later, just shows the level of professionalism from this guy.
I've been rewiring/designing wiring harnesses for forty-plus years now. They have been mostly custom one-offs on almost anything you care to name. I always give the owner a copy of the diagram and I keep at least one copy myself. On the shelf behind me is an A4 binder with hand-drawn custom wiring diagrams as far back as 1985; from about 1992 I started doing them electronically but I still have copies of those too. I don't do it professionally but I keep everything I ever do - just in case!
So 4 months ago this bike was on Bikes and Beards, and that guy who did the wiring had offered to buy it for $15k. Now he's on the phone telling you how to fix it, lol.
@OneManParade you run a garage? I give him a little slac, he was smart enough to take money from discovery channel and somehow get people to buy the garbage they glued together. Only worth any of the bikes has is maybe the engine
Amongst the many ludicrous things wrong with this bike, I love the "air cleaner" the most. It cleans the air outside of the bike by sucking in dust, debris, small birds and wayward toddlers and putting them safely into the engine. Great design!!
Mad props to Stephen for helping on this so much when in reality he didn't have to especially the way customer service is now but he has been helping in anyway possible shows a lot about him the company and the pride in the products and work he does!!
What do you mean "the way customer service is now"? Unless you are dealing with huge corporations, businesses now know we have so many options and they compete on service. I always try to use smaller companies when possible and 90% of the time have great success with customer service when I need it.
I took a sip of beer every time you said, 'this wiring harness was made specifically for this bike', got drunk and fell asleep before the end of the video.
Exactly right. Also, some moron thought that RTV is a gasket and bolted everything together with only RTV. Idiotic. As soon as the first component was removed without any gasket showing the entire bike should have been disassembled top to bottom, gaskets built, and put together by some that has ever worked on mechanical devices. Anyone that has knows knows that the uploader has never built anything in his life. Every single thing about this, from the diagnosis method, to the identification of the problems, to the solution is high school level thinking. This level of incompetence would have not gotten you a job as a gas station mechanic or an auto parts store clerk in 1985, forget about nowadays, lol.
yep ditch the super charger spinning belts of death by your face and remove crazy brackets, match yellow paint nice and put turbo down low on it now you have clean, safe power problem solved
As a promotional piece, it was not meant to be practical. It was supposed to insane and over the top, and they certainly accomplished that. It didn’t even need to run to accomplish their goal, if that tells you anything.
The guy across the street from where I managed a Chevrolet store bought Anna Nicole Smiths pink chopper. He was bragging how it’s gonna be worth a ton of money. It’s a collector’s item! He told us. The day it arrived we went over to look at this monstrosity. It literally looked like a group of 12 graders put it together in a high school shop project. It was terrible. I felt sorry for him because he spent a ton for it. As far as I know he still owns that pink turd.
From Germany. The error is quite simple. The fuel pressure jumps back and forth, but is not regulated. However, this is necessary depending on the speed and pressure from the compressor if you do not have a lambda sensor. As there is no lambda sensor installed, you have to install a fuel pressure regulator behind the pump and connect the sensor line between the cylinder and the compressor. The fuel pressure rises and falls with the pressure from the compressor. The injection nozzles then inject more or less fuel at the same cycle time (!) because the fuel pressure rises with the compressor pressure. This is technology from the 1960s and 70s.
ya thats what was confusing me. the fuel pump SHOULD run all the time and have a constant fuel pressure. idk how ANY fuel injected motor would run right without regulated consistent fuel pressure.
Hard to imagine it ever ran right without some kind of regulation. I wonder if whoever worked on it last had no understanding how EFI works and just plumbed it like you would for a very crude carb setup. Even some carb setups need regulation if you update anything above factory, and this bike is custom from front to back. It's possible the output pressure from the pump is matched to the EFI requirements like some factory setups are I suppose. That would seem unlikely with all the forced induction variables, but not impossible. I guess we're going to find out as this project progresses.
@@woopimagpie The amount of cars I have worked on where some old bloke used to carbs tried to apply carb fixes to EFI systems is absurd. My current truck had the anti-diesel screw turned all the way out and holes drilled in the airbox, because it had a bad MAF sensor that had overstressed and ruined the IAC. Previous owner knew enough about engines to know there was an air mixture problem, but didn't take the 2 seconds to look up things that could cause that on an EFI. Tried adjusting the idle with something that looked like a carb adjustment, and when that didn't work just went crazy with a drill.
you can see the regulator on the pump assembly in the tank. it is a dead head system, not a boost reference regulator. This is fine, you can tune around this and it's not a big deal. The fact the pump was always on is not an issue for it running. It is only a safety issue.
He said he pulled all the power out of the tune to prevent anyone from doing something unsafe. The plan was to add the performance tune back but he never heard back.
@@legion7478 Oh wow, you actually bought one? So I take it you base your opinion on first hand experience or are you just a know it all who is ticked off that your mommy won't let have a motorcycle?
12:11 smoke machine. Seriously useful tool in any ICE shop. There's even some, specifically made for being piped through and into motors. Useful for exhaust leaks, useful for valve issues, intake leaks, fuel leaks (yeah, that too) and more. For how little they occupy and bite your wallet, not having one is a disservice. I'd get one that comes with a plate kit (meant to be sealed against the face of an intake), hoses and various fittings.
I remember my dad, a lifelong mechanic, constantly complaining that OCC were bad at making bikes. He'd often say similar things like how it would be hard to fix them, etc. One complaint I remember vividly was they always painted the parts before making sure they all fit together, thus making even more work when they inevitable had to change something and then repaint the whole thing
I never saw OCC as trying to make a real bike. They just bashed what they thought was looking cool together and didn't care about it actually working or being safe. The safety was the least important thing to them. Now I remember that there were some other show where they took someone's car, rebuilt it and refinished it in a few days. That was pretty similar, though sometimes they did surprise me by doing quality work. I have wondered about those more questionable builds they did. Just how long did it take before they fell apart, and were they worth trying to save after that? I also might be confusing a couple of different series. I remember one episode when they built a truck for Stallone, modeled after a truck in one of his 90's movies. In another episode they rebuilt a really old Porsche really well, making it look like new. It belonged to an older gentleman who had been "rebuilding it" for a couple of decades but now had been diagnosed with cancer and really never would have been able to put it all together again. Like I said I'm not sure they were even in the same series. Still wonder if the quality of their work was any good.
@@pauls5745why would he care. They made tons of money and elevated their business profile. They only benefited from the made for tv motorcycle fascination
OCC bikes were show pieces at best. They were never meant for serious riders. It was fun watching them design and build the stuff, but riding one never crossed my mind. The Geico build looks like the most uncomfortable motorcycle ever built in history. It's shocking that they lost everything....LOL
I see lots of diagnostic lessons were learned. This is why after 17 years in automotive fixing all makes from 1920s-2020s, I still learn something every single day! Great job!
I have watched a previous video of you dealing with this bike. I appreciate your intestinal fortitude and determination and fixing said Bike. Wonderful video I am rooting for you.
Should have called me. Seriously. I used to fly to dealerships and fix vehicles nobody else could. It almost always came down to basic principals and incomplete procedures during diagnosis. I would have started by using a rat file, in the mounting boss for the tps. You can get a bunch more adjustment, too get your zero. Also, It would have been a good idea to do a voltage drop test. If your ground isnt excellent, itll screw up your 5v reference voltage for your pcm, and all sensors. Ive also seen aftermarket ignition switches drop a ton of voltage across them and its confusing as hell, when youve got 12.8v then suddenly 10v. Lol Vacuum leaks create lean conditions. Also creates high idle, that the iac starts "hunting" to correct. Its unregulated air that hasnt been read by the maf. You stated black smoke which is a rich condition. I like a good puzzle! Im about half into video currently. Good video. Finished. Wow! What a devil! A couple tools I suggest adding to your set that have served me well. 1. A Power Probe. You can give power and a ground with it. Great for fast diag. 2. A relay swith set for both large and small relays. Just pull questionable relay, put in correct sized swith, and you can turn your circuit on/off at will. I still think you should notch the tps, too get a little more adjustment. Also check that boost sensor again. Is it a 2 or 3 bar? The resolution makes a HUGE DIFFERENCE depending on the expected boost its meant to read. I could be wrong, but Im thinking you should have a 2 bar on that. Again... Great video!
hahaha.. even better. a series where each member of the occ crew has to pick one of their show bikes and roadtrip them across country, fixing all the screw ups along the way. granted, it might take the majority of the first season just to get the bikes going well enough to leave the city they have to start in.. LOL
@@user-xx8rn5yg9g some of these bikers want that "rare" "one of a kind" abortion. "yea i want puke green advertisment for geico" where how it looks and how weird it is matter more than if its a good bike. OCC bread and butter. some of them do look really cool but like alot of supercars ect owning one can kinda sucks
I'll never understand... The guy had the bike's builder working in a shop space right next to him. But instead of tapping that resource, he brings it to a string of yahoos that have probably never even seen a supercharged bike...
I don't know about America but in Australia I work as an auto electrician. We basically take over when the electrical is out of hand for the mechanics. You had a good crack and had people giving you great advice. For me. It was exciting to see a good video of custom work with electrical issues. Feels like it's way too often dodgy mechanical haha
@@michi_danksta @screwhead4202 @slowstang88 @charliepatterson9321 I will never forget Mr. Martinez from the 7th ad 8th grade, he cut off his thumb and ring finger on his left hand. His wife was so damn hot, we never figured out how he landed her. We were young...
I don't like bikes, I'm more of a car guy, but after following all the drama I arrived here, then, after I saw this relentless mechanic work relentlessly I sub'd. This was awesome.
Craig, I’ve got a 1983 Honda shadow 750vt if you want it. Been sat in a barn for 7 years since my son was born. Fired up lovely 2 years ago, tank taken off to change perished fuel lines then left again The only problem is it’s in Wales uk 🏴 Come on over! You know you want to do an international episode
There was the proposal here for a follow-up series, to try to fix all these OCC crapheaps. I'd call it, "Fix or Flame?" where you decide whether a thing is fixable or should be ritually destroyed. In the case of this ugly heap, independent of its problems, the outcome is too obvious to warrant an episode.
it was a reality TV show. They made show bikes. I wouldn't call them art, but they're definitely just for display. I'd be surprised if they run for more than just the showing. I also don't think anyone was taken to the cleaners. We all know the deals on Pawn Stars were fake, with many paid actors as the customers. This is all promo stuff to make a show and advertise for the company of the week. And don't get me wrong, I don't even like these bikes, but reality TV is reality TV.
Man, what a challenge. I had a similar headache back in the day with my Yamaha RZ350. For weeks I tore it down, built it up, tore it down, built it up and then one day through so much online searching (this is back in early 2000 when info on the web was minimal btw) I seen a guy mention he encountered a similar thing to me and suggested talking to this old warhorse in California who had been a mechanic working on racing these bike since day one. I called him, he flat out said "I know what it is". Just like that. He said "send me the brain box and x dollars and I will fix your problem". So, sent him the little black box (a factory sealed unit) and got it back a few weeks later and get this... he put a half inch dowel across it and held in place by two pipe clamps. This added pressure from the dowel across the unit on a specific area. That was the fix. I plugged it in and ran that bike for years until I sold it. Jenky fix? You bet. Sure, he could have told me over the phone what to do... I was a bit annoyed by that. But... I got to enjoy my ride finally. Electrical issues on bikes can drive you mad.
You didn't pay him for his time or some elegant solution. You paid him for his experience, knowing what the problem was, and the fix. Maybe the fix was 'jenky' but . . . it worked and that was enough.
@@mikeg7411 Reminds me of this reddit story where a locomotive engineer was forced into retirement cause he only knew how to do things the old way. Then they call him up to fix a problem with an old engine they couldn't figure out how to get the train moving (for some anniversary thing). Basically charges them an arm and a leg along with the travel costs, has them start it up, listens to it then whacks a couple locations with a mallet which fixes the problem they were having.
Craig you had a whole lotta patience to try to figure this one out. I love every second of it 😂. I still don't own a bike yet but I love watching you fix and ride them 😎.
Craig, this series has aged you. You started out looking like ....well you. At the end of the vlog, you look like Heston in the Ten Commandments movie, after he came back from the mountain!
I don't have much interest with bikes, but I love watching engineering and mechanical videos. This was an amazing watch, so well made and explained, can't wait to watch more!
OCC was NOT about the motorcycles. It was just cheaper for large companies to "Buy a bike" and then get an HOUR LONG COMMERCIAL for their company in return - with a stupid bike that was never meant to do anything but start up and run.
I was always amazed at how the OCC crew ran into the same problems show after show after show... I learn from my mistakes and strive not to repeat them.
They built em to look pretty in a lobby and maybe rolled on stage and revved up at a corporate get together. Stuck together well enough to be a giant billboard
I don't think they should be destroyed, but at the same time, i can't take anyone saying they're functional bikes on, without laughing a bit. I really liked the early OCC bikes, that were slightly more traditional... but the later stuff went off the deep end for views and ... that's what ducked them. They weren't a business for business, but rather a business for views on Discovery. Which is a mistake you wouldn't think people with previous businesses like they had, would make. Business is business, views are views, popularity and fame are separate as well. You don't mix them, only Jason Statham is Jason Statham.
It also didn't blow a huge puff of black smoke when it fired up after getting the fuel pump to stop. Probably because it wasn't forcing an overload of fuel pressure into the injectors. Don't give up. You'll get it. We all have faith.
I had to deal with an interment left turn signal problem on a car for years. When I tried to fix it, no problems. Then get back on the road and no turn signal about 15% of the time. I never did get it fixed before the transmission went out. Now that 15 year old car is the junkyard's problem.
You have many tenacity units. More than most. Love watching your methodical approch to the repairs. Im learning how to swear less and enjoy the process of figuring out problems by watching this channel. Thank you sir.
Orange County Choppers built bikes that are meant to be stationary pieces that people just look at. There was a time at the "turn of the century" when these and other bikes became really popular because of TV. People realized that they had disposable income and could easily purchase one of these bikes. Everybody started making them! O.C.C. never "produced" anything. They bought frames from one person, engines from someone else, transmissions from another source, etc. The only thing that OCC did was make some fancy handlebars and weld together scrap metal to make a sissy bar. They were never meant to be ridden so it's no wonder that this bike never ran correctly. Awesome that you were able to get a hold of Steve Thompson and that he was and is willing to help you get this bike running! Maybe you get a Discovery Channel show where you do a revival of the Teutle bikes, one per show. Lord knows they would never be able to figure this out on their own, even if they put all three heads together I doubt they could come up with one singular brain. 😳
The idle air bypass has been on my mind the entire video. Not sure how that should be working on the supercharger, but if it's downstream of the pressure right now it's causing issues.
and wouldnt you just check it by spraying carb cleaner around all the joints that might be leaking? Listening for changes to the idle while you do it. thats how we do it with cars. I am no motorcycle expert, but it was a little frustrating to see so much speculation, when you can actually check these things pretty directly. The idle speed is usually controlled by that idle air bypass, and if you are idling at 2600 that is not working as you said. Fix the easiest problem first, work on the map second. Hell i would disable the whole idle air bypass system and just use minimum air at the throttle blades to keep it simple until its all sorted. The TPS thing seemed kinda silly too. the program was up on the computer, they could see what the TPS was saying. If it wasnt reading zero, the wiring harness might be complicated but the TPS is 3 wires usually, and you can follow those into the cpu. That needs to be sorted before you do anything else. It just didnt seem like they were having intermittent problems, or unreproducible problems. Those are the ones that drive you insane. The problems seemed very straightforward and fixable. But its hard to tell from a just the video thats meant to be entertaining, and thats fair, i get they need to make interesting content.
This guy would need to buy a clue to get one. He is checking for vacuum leaks on the output side of the blower. What the... even if it wasn't making boost it would have sufficient pressure on that side not to be an issue. Clearly the VACUUM leak is on the inlet side of the blower. And why did he need to be told to check for a vacuum leak? Anyone that has ever experienced a vacuum leak knows that it idles high, why wasn't this a first step before anything else was looked at? Then there was the whole look at the engine change when I turn the TPS. Well duh, you are altering timing you are altering the amount of fuel being delivered, even if you don't move the throttle blade it is going to alter the revs. Where is the spray bottle to detect the vacuum leak. Again any mechanic that has ever fixed a vacuum leak starts with spraying around the suspected area to see if the revs alter as the water plugs the leak. He hasn't even looked at the most obvious place the vacuum leak is going to be. The TPS is connected to a shaft that goes through the throttle body. There is going to be a bearing in there. Good chance it is sucking air through those bearings. They probably don't have seals on them, or the clearances are too big.
Anyone who rides knew that the bikes were for show. They're nice looking bikes but they had 1.5 to 2.5 gallon fuel tanks, stiff or no suspension, and bars set in the most uncomfortable positions. They were building bar hopper bikes at the most.
Do you not have a smoke machine? Just turn that on and push the smoke into the intake. Where the smoke leaks out is where the air leak is... We learned this in school
If you're ok with being known as a hack and a fraud forever in exchange for a few dollars then I don't know what to tell you. Not sure I'd ok with it. I'm a contractor and I like my good reputation. I doubt I'd ever sellout. I'm not motivated by money.
I was on a flight from Tampa to Raleigh a couple of weeks ago and saw Paul Sr. The TSA dudes wanted to take pics of him with his wife. He still looks and dresses the same as on the show and his wife had so much plastic surgery she looked like a toy. Anyway, long story short, he was on the same Delta flight as I was to Raleigh, NC and had a basic economy ticket and sat in the very back of the plane....hmmm
My hats off to you for trying so hard to get this expensive boat anchor running right. Me personally I would have quit after about the first hour and just stripped everything off of it that actually does work and put it all on a frame that makes sense and been happy just to have a running bike. This really speaks volumes about OCC and their fan boys who say they build awesome stuff. Personally I've only seen nightmares and garbage come out of the OCC shop.
Or just install a newer more updated EFI system that is easier to tune and then you would know what you are working with,he would have less time in the bike by now for sure
Having no experience working on one, I was given a 24 year old YZ125 that had been sitting for at least a decade. It had no compression and a multitude of other little issues all over the bike. I tore it down over a few weekends. I rebuilt the carb, honed the cylinder, put in a new piston and rebuilt a lot of other smaller things on the bike. It’s now running exceptionally well and I’ve taken it out for a few rides at this point. Thanks for being an inspiration!
Great video and very impressed with your control and frustration balance! I think I was getting more frustrated than you and I'm not involved!!! Awesome channel!!
I cannot even imagine someone saying with excitement "this build was 'managed' by Paul Sr.!" and thinking this is NOT what you'd be dealing with. lol. Good on everyone involved for taking this project on.
Happy Birthday Craig! 🎉 When it comes to vacuum leaks, trick I use is; start it, take a UNLIT propane torch, pass it along hoses, connections etc, if the motor revs up, you've found your leak.
Most of OCC bikes were complete failures because Paul Sr. wanted a custom theme bike done in one week and he would go into a roid rage if Paul Jr. wasn't working fast enough.
Watched it through to the end. Looking forward to seeing the man who gave you all that help over the phone. A class act! And yet,...another good one here. Cheers! 👍
I've been working on bikes and cars more than fifty years, building engines almost as long, my son used to love watching OCC and I often watched with him. I've always thought they were just show hacks and in no way "real choppers". With the limited success you achieved, I'm still convinced. In all candor, I don't even like anything more than the most basic electronic ignitions on bikes. My last coast to coast trip on my 96 chopper ended up with points replacing the dyna s ignition which failed somewhere in Texas, coming from eastern N.C. I'm hoping my next round trip will be on the 42 WLA I recently bought and am prepping for a long ride.
what he didn't tell you, apparently, was that you have to keep turning the crank on those old laptops at least every 30 to 40 seconds or they would power down 😳
I did the fabrication on this bike. the amount of hands that got into that bike after it left occ is the real problem that caused all that. Its awesome you were able to iron it out! Steve Thompson was super impressive to work with
I suspect the Tuttles started to outsource more of the work they usually did in house when they realized they had a brand with OCC. The empty giant OCC building in New York is proof that they grew too fast and didn’t manage their business better
@@matthewcaughey8898 I happened to drive by that building once. I thought it would be in an iconic location but it's like the corner of a shopping plaza.
Huge credit and thank-you Craig and crew! Big thanks to that original tech guy who put it together originally for his patience too. Enjoyed your excitement and felt your frustrations! 😊
I'm kind of surprised he didn't even use the old "spray brake clean around fittings to see if idle speed picks up" trick. Not to mention that TPS needs to be calibrated. Dude seemed a bit out of his depth.
