The Twin Cam 103 is where Harley-Davidson took all they years of twin cam improvements and put it in one place. If your looking for a late model twin cam Harley most all of them are going to be powered by the 103, with exception of CVO models. These motors already produce more power stock than previous versions in the 88 and 96 inch, but what if you want more? We'll take a look at the ways to get more power and just how much these parts going cost.

I love my bike

@wallywire 11 месяцев назад

Cams are the trick in this kit. Are the 585 the same cam as T-580s ? My kit is due to come in 8/19 after waiting 14 months. My gut says I need to change out cams in the kit. You guys use ThunderMax tuner?

I bought the 2015 Road Glide Special out here in Cali and with the smog is was a DOG! Ran hotter than hell, didn't get 200 miles on a tank and had no throttle in 5th & 6th gears. Purchased the Screaming Eagle race tuner. Installed a Roland Sands intake and Reinhart slip ons'. Took the stock exhaust off, emptied out the catalytic converter chamber and reinstalled it. Had to take it to Arizona to have it dyno tuned. Like a brand new bike. 92 hp with 113 torque. Runs way cooler, 240 degrees when it's 100 degrees outside. I get 230 to 240 miles on a six gallon tank. And of course, it's not the fastest bike but nobody leaves me in the dust. This thing is a rocket ship recliner. These days Harley is begging me to trade this in on the M8. Thing is how do I take the Cali smog off this thing and pump it up like every other Harley I've owned? The stage kits are crap and full of problems. These things eat, breath and fart. You improve this on the Harley it's like you have a brand new bike.

It’s all in the heads ! My 2015 RK I used my stock pistons and sent the heads to zippers performance for there mildest CNC port they offer called 1.8 for the slightly larger intake valves 700$. Put it back together with.030 head gasket and heads decked made it 10.25 comp. I already had Andrews 57h cams & powervision with cobra power port headers & SE street cannons. So this is the cheapest big gain set up you can get. & never even had to remove my cylinders. Had it dynoed with the powervision & ended up with 108 hp & 116 TQ & a very happy customer 👍 I did it with 14000 miles on it. Forgot to add I did it all myself including the cams a year earlier so no labor costs

@GixxerFoo 3 года назад

The 103 during the 88inch era was only in the Screamin Eagle CVO bikes. The replacement motor for the CVO was the TC 110 when the 103 made it into standard production of all models. But at that time the 103 you're talking about isn't exactly the same as 2009 103. This 2004 103 shares much more with the 88 in that time period.

Let's face it HD has to make engine mods. Other than paint how can a HD be improved. One of my Twin Cams has 78k miles and she runs like a dream. The M8 blow oil smoke sometimes and you definitely smell oil burning on start up. Most of my family think the engine sucks. Only because HD has not come clean about this engine. First the oil migration to the primary and now HD is on their third oil pump improvement....not to exclude the new M8 oil filter they rolled out....why? My two M8 only have 6300k miles between them so time will tell. They both are getting the new SS came plate and oil pump in Oct 2020 when I have time to replace them.

@GixxerFoo 3 года назад

Have you had your M8's in for all the updates? I saw they started drilling the case on the primary side and putting a vent/return tube in there. Seems like something they would of caught in development. I've talked to several people that came from a TC to an M8 and they said the same thing.

Problem is I could get a 2017 used for only $1,000 more. I'm not a speed freak, I'm just concerned about the big three wheeler moving when I need it to. What would you do and why? Thanks for any reply

@GixxerFoo 3 года назад

Thank you! The trikes really needed the extra power of the 107 and 114 M8's, but the 103 does very well and a cam swap will really get the horsepower and torque where it needs to be to really pull a trike. Now the 2017 M8 had oil sumping and oil pump issues, I would take the VIN to a dealer and see if it had any warranty work done. 2017 engines with the original oil pump design had the issues and Harley replaced those with a newer designed unit under warranty. If you are able to verify that I would go with the M8. But the twin cam 103 is tried and true, they got the issues with the twin cam worked out on the 103 and of course they changed over to M8 shortly after. My opinion is the 103 is less likely to have an issue vs. the 2017 M8 which was the first year of that motor, I've had some bad experience with the first years but that's just me.

I should have read a LOT more about the 88 because I found a decent LR with the 88 with everything I wanted on it---low mileage, rack/bags/shield/engine guard/back rest/ and good paint and not bad for rust. It has been one problem after another. Over and over , thousands spent just to get it running AND haven't even't replaced the chain tensioners yet. Such a disappointment. SO, spend some extra money and buy a late model 96 or the 103. Even a nice 88 with low mileage COULD be a real POS.

@GixxerFoo 3 года назад

Then 88's were really hit and miss, some were flawless and others had all the known issues. The later year 88's weren't too bad but the 96 had the issues corrected by then.

@Super2wheeler 2 года назад

I just bought a 2010 Ultra Classic 103 and it's leaking a few drops of oil every day. Oil and trans fluid are fine. It looks like it's coming from where the pan bolts onto the bottom of the motor. This is my first Harley. Any ideas where it's coming from? Do they have a reputation for leaks?

@Rem700R5MN 2 года назад

Thanks for your great videos! They are super helpful without being overly technical. I recently bought a 2016 Fat Bob that was almost new, only 230 miles on it. It has the 103 HO engine. I put about 2500 miles on it before winter shut me down. I am looking to give it some performance upgrades over the winter as it is still completely stock. What would you do if it was your bike and you had a winter to do it? If you need a budget let’s say $7500. I am looking to do the work myself so it can all go for parts. I am looking at a 2-1 exhaust system like the V&H Pro Pipe, and a set of Wood TW-222 cams, S&S cam plate and high volume oil pump (mostly based on your video- thanks!), and a Powervision tuner (from your video too-thanks!). So far all I’ve purchased is a K&N RK-3934 air intake system which I replumbed the breathers on to keep oil and hot gas out of my intake (also based on another of your videos- thanks again!). What else should I do to gain some power or make it run better without replacing the jugs or bumping up the displacement? What kind of a performance increase could I potentially get if I were to have my heads ported and polished or even replaced? Not scared to spend the money as long as I get something in return. Thanks again for your great videos I watch all of them. Hope you can respond, your opinions would be most helpful! Merry Christmas!

@GixxerFoo 2 года назад

Thank you, I appreciate it! Really the biggest bang for the buck is the cam, and from there a big bore kit. Head porting will help some, but not any major gains for the money spent without upping the compression.

@Rem700R5MN 2 года назад

Thanks for the response, sounds like I am at least on the right track. I am working my way through your twin cam videos. I got some time to figure out what I want before I start ordering parts. Now looking at the cost of bumping up to 110” with the Fuelmoto kit (yep, based on another one of your videos) and now I’m not so sure I wanna keep her at 103”! Thanks again for the videos, hope you have a great Christmas!

@thakery5720 3 года назад

If you are looking to re-build an engine with the goal of power, it'd be better to score a 110 engine and use the 117 'drop-in' cylinders as the heads are a much better casting. Get the heads fitted with bigger valves and port them and your numbers can be over 140 in torque and horsepower. If it is a rubber mount bike though you will have to upgrade the engine mounts in order to stop the dreaded 'death-wobble'.

@GixxerFoo 3 года назад

I've heard of the death wobble and know some guys who had monster S&S Dyna Engine builds that experienced it. There are after market stabilizer links for the engine mounts out there and they do wonders!

@thakery5720 3 года назад

@@GixxerFoo Yes, but stabilisers are not enough when you get up to high power levels - you need different mounts. I use ones from Big Bear Performance as they offer a little sideways adjustment on the front mount that enables you to get the wheels aligned properly. My Sporty's mounts were old and buggered so I fitted ones from Drag Spec as they are firmer and the handling on my Sporty is great now. If you were to see my bikes you would be in awe as so much is changed or altered..... my brother in law says it's easier to remember what parts I haven't changed, modified or re-engineered. I have had the bikes 11 years now and it is a constantly evolving situation. My Dyna has had over 3250 spent on it including original purchase price (new) and the Sporty about £10k but that one was second hand.....

@GixxerFoo 3 года назад

For a 96 you can do a 103 kit through Screamin Eagle. Aftermarket kits you can bolt on up around 124 inch. Technically the 110 kit would work on a 96 through Screamin Eagle but it wouldn't be warranties. The 131 engine is a M8, it wouldn't bolt into your bike but with some creative fabrication it could be done.

The kit is going to replace the bearing you can get to, you'll be replacing the left side output shaft bearing as well. That's about all you can do to the bottom end unless you're splitting the cases and having the crank worked over.

@mrnonpc9885 3 года назад

I have a twin cooled 2016 103”, and want to do a 110” upgrade. What’s your opinion about switching to gear drive cams? Also you mentioned in another video about the CVO 110” that it had a SE compensating sprocket. Do you know if my 103” 2016 FLTRU Mount Rushmore has the upgraded sprocket, and if it doesn’t do you suggest upgrading to one? Thanks for your advice.

@GixxerFoo 3 года назад

I really like the gear drive systems and they are great for the 88's with spring tensioners. The gear drive have more accurate timing but they depend on the main shaft run out being a max of .003. Not only for installation but throughout it's life cycle, if it's any more than that you'll need a new crank or stay with the chain system. The late model bikes like yours have done great with the hydraulic tensioner system, it just need to be inspected about every 50k to be safe. The 103's do have the stock compensator, but they haven't failed like they did on the 96. Personally I wouldn't change it unless I was having a problem. Just don't go back with OEM if you have a failure, go with the Screamin Eagle.

When bigger cylinders and higher compression pistons are added to the 103, would these things effect the dependability of the bottom end. Crank, bearings etc.? Thanks, I enjoy learning any new information you may impart upon me.

It's always a possibility but a lot of that depends on how hard you are on the motor. If you just ride it and not beat on it constantly, take good care of it, it can be quite reliable.

You're right, there was a variant of the 103 before 2009, it was a limited edition engine for the CVO models. These engines weren't mass produced, they only built maybe 150 per model a year as CVO models are limited production. The 103 before 2009 had way more in common with the 88, including the spring tensioner system, heads, cams, compression ratio and a 5 speed transmission. The 103 that came out in 2009 was for the mass produced touring bikes and had all the updates of 96, I should of clarified that in the video that it covering the mass produced version.

If you keep it mild and don't beat on it the stock crank will be alright, they are pressed cranks so biggest thing is just not lugging the motor. I would get at 120R before the ST, the ST is the same engine as the R but the ST has a milder cam.

@GixxerFoo 2 года назад

They are really great bikes in their own respects, I might be a little biased cause I really like the Dyna Low Rider. A Softail Slim is great riding bike but it does sit very low to the ground and doesn't have much cornering clearance. The 1200 is a fun bike, I have a 2016 1200 custom and my wife rides a 2017 Sportster 48. But if you're running down long highways it's gonna get real small after a while, I'd say the Dyna would would be my pick. The Low Rider is like a big Sportster, it has room to stretch out and it's a lighter big twin but it will still ride good down the highway.

@GixxerFoo 3 года назад

You could go with a new set of cams if your targeting low to mid range torque, but if you're interested in a 110 I would go with the stage 3. It doesn't push the power all the way to the top of the rev range like the stage 4. The stage 3 110 kit produces just under 110 ftlbs of torque at only 2500 rpm.

@GixxerFoo 2 года назад

If you plan to go that far with the bike and the mileage that it has on the current lower end I would go ahead and do the crank. That's a lot of miles down on the bottom end, planning on a cam plate you'd likely find the run out on the crank is too high. You'll need run out ideally at .003 or less with a billet race cam plate.

Based on your I see deep knowledge what do you think about the flywheels scissoring; on the late TC103s it's still an issue to be concerned of?

Wood 222 is going to be the best all around bolt in for your setup, that cam really excels in heavy bikes with the torque curve and top end power.

On the 103 there were so many different variations of the stage 3 kit at that time it would be hard to tell without tearing the bike down measuring the bore.
