670 Predator Mud Motor | Rebuild and mods for more speed! 

HA HA HAAAAAAA that was aweome! You are my hero for the rest of the day!

@@SendItJonBoats 😂

HAA HAAA... I felt my simulated engine revs were pretty accurate. LOL. Many more videos on the way. We got to get this monster in the water soon!

Heck yeah man! I need some places to go ride, all we got here in GA is shallow sandy water and little bit of mud,

I have the outer filter cover, just forgot to install it for the video. Will have an update video soon, first test run was a bust, something was going on with the battery and fuel, maybe the pump. We are getting it sorted out and will be back out testing it again soon. I would like to see over 30mph with the mods.

Something about a clapped out lawn mower engine really gets me going.

It was worth the time and effort. I really like it.

Nice... I voided the warranty first day. Took it out of the box and started ripping stuff off. LOL

Good info thanks for sharing. I probably will never go bullet on this engine, I never turn it up past 5k rpms anyway

Thanks Lem! Somebody gotta say it... might as well be me! LOL

@@SendItJonBoats LOL I love it😂

Thanks for the sub! LOL. I like to make funny noises sometimes.

Thank you sir! Glad you enjoyed the video.

Awesome, thank you! Glad you enjoyed

Thanks Tom. I really like the deep sound, was a great purchase.

I like to get real technical... muuuuureughhhhh... Right there!

It sounded amazing in person. My neighbor thought I bought a new harley, so he came over to see it.

Bye Bye politicians! Yee Yee!

It is only fun when it is dangerous

@@SendItJonBoats Yes Sir!

Awesome, thank you!

Yeah I wish I could turn it around but it wouldn't work. I even thought about putting a 90 degree tube on there to get it up away from the exhaust, but it seems to be working fine.

LMAO. I laughed way too hard at that.

It is insane in person, sounds like a freakin harley on steroids.

Thank you Mark. Appreciate you checking out the video.

Thanks

Thanks Wilson! Gotta keep the laughs going, life is too short not to have fun!

Ol scooter always gotta hate! LOL Someone has to clean out the fridge and make room for the summer beer!

I cleaned it up some before I put the cover back on. I may need to bust out the sand paper if I can get another 30hp out of it! LOL

Just a little technical clarification. So long as the rust isn't so thick that you can't turn the flywheel, sanding the rust off the magnets doesn't do anything for the modern electronic ignitions. Setting the proper gap between the coil legs and the flywheel is important though. It should be set to prexactly one business card thousandths. (Please Note: Actual specs for the Harbor Davidson 670cc V-Twin Engine are: Flywheel/Ignition Coil Gap: 0.0015" - 0.0018" Intake Valve Lash: 0.005" - 0.007" Exhaust Valve Lash: 0.007" - 0.009"

@@bob2161 I glad someone knows the correct cap, I looked around and found a million different suggestions.

@@SendItJonBoatsGreetings, this message is for Mr. It. Mr. Send It, I was reviewing my previous comment, and thought I had screwed up, but actually, I was mistaken. THE COIL GAP OF 0.040" IS WRONG! I don't even know which hole I pulled that number out of. (The 1 business card thousandths is correct though.) It will probably (maybe) run at 0.040" but there's a good chance you'll be leaving a good bit of whoop ass still in the can. I'm including the correct coil gap and valve lash numbers below. I'm also correcting my previous comment. Goodness knows I don't want to be creating any more than my fair share of confusion. Please accept my, ever so humble, apologies. Flywheel/Ignition Coil Gap: 0.0015" - 0.0018" Intake Valve Lash: 0.005" - 0.007" Exhaust Valve Lash: 0.007" - 0.009" I'm still working on tracking down the timing and frequency settings for the canooter valve modulator, and the torque specs on the nuzzler bearing. I'll have that to you forthwith and post haste. Eventually.

@@SendItJonBoats Sorry about the delay. I got involved with another project . . . I'm sure you know how that goes. Determining Proper Settings for Canooter Brand Valve Modulation Units. (Specifications included are for the analog series of Canooters. Specifications for the digital versions are not included.) Canooter brand modulators are considered to be the "Gold Standard" for valve control in attenuator and filter valve modulation applications. The robustness and longevity of these units means it is not uncommon for Canooter units to be handed down from one generation to the next. We are quite proud of this legacy. Today though, most of the high end modern units are digital, and are pretty much plug'n'play. They are programmed to function in a wide range of applications. The programs include algorithmic diagnostics that control the automatic setting adjustment parameters. Thanks to this kind of forward thinking by the Canooter brand design engineering department, retrograde deficiency errors or failures are practically unheard of. This reliability has lead to the exclusive use of Canooter brand modulators throughout the entire dilithium mining and processing industry. We are proud and honored to be recognized and trusted by this important industry. However, we realize that we would have never obtained such an achievement if it were not for the longtime support we have enjoyed from our millions of individual owners. Most smaller or independent operators continue to use the older, simpler, analog units. These analog Canooters have long been praised for their "Set it and forget it" ease of use. Of course, after enough time and use, even these analog units will need to be recalibrated. We offer the most advanced Canooter diagnostic tools available. These are used extensively by the dilithium mining and processing companies. However, this caliber of recalibration instruments are financially out of reach of the small independent operator. To address this inequity, we have continued to offer our older analog meters. These are the kind that the "Little Guys" can afford and use, while still having great results. Just follow the simple instructions below, and you can be confident that your old Canooter will be right back to original factory calibration, and will perform at peak efficiency. Once recalibrated and reinstalled, your Canooter brand modulator will give you many more years of trouble free service. First, locate and remove the turbo fantabulator unit from your machine. NOTE: Turbo fantabulator units are most often installed in close proximity to the primary recipitory bearing trunnions. Second, secure your turbo fantabulator to the bench. NOTE: Extreme care should be exercised while securing the turbo fantabulator in order to avoid damage to the secondary wobble vane assembly. Third, separate the Canooter from the turbo fantabulator housing. Remove any refractory debris that may have collected in the Canooters inlet port bypass chamber. (Remember that all refractory debris should be handled and disposed of according to the biohazard protocols applicable to your region.) Fourth, securely connect your Canooter brand analog recalibration meter to the cleaned inlet port bypass chamber. NOTE: Insure the recalibration meter is in an upright position. If the meter is leaning, it will bias the results of the recalibration process. It is especially important that your meter does not lean to the left. Operating your Canooter unit when adjusted to specifications of a left leaning meter will result in a catastrophic failure. It is reccomended that left leaning bias be avoided. Fifth: prepare the face of a two pound hammer with a wedge of fresh lemon. (Rubberbands may be neccessary to secure the lemon wedge firmly in place.) Sixth: Using the bottom of the hammer handle (in the same fashion you would while installing a piston into a cylinder), tap the Canooter modulator output shaft. Continue tapping the shaft until the TLAR* indication is clearly displayed on the meter. Congratulations, you have successfully recalibrated your Canooter valve modulator. Reinstall all components, reverse order from removal. You can expect top performance from your machine, as well as an increase in fishing yields and the reversal of any male pattern baldness being experienced by you or close fishing buddies. *TLAR = That Looks About Right

Yeah man, get em clean baby!

Yeah I am going to keep it under 5k until I get the new cam and billet parts. Really don't want to have watch a rod go through the side of the block.

Yeah babyyyyyy!!!!! Let er rip tater chip!

It was already broke in for about 30 hours before I tore it down, and I did not remove the pistons, rods, or crank so it will be fine. That thing will rev to 9k rpm if I let it, those little blips on the throttle were about 4k rpms so no where near damage range.

Thanks Christopher. Can't wait to get this bad boy on the water

I love that exhaust

Heck yeah man, I love finding new hidden fishing spots.

I got them at Harbor freight, comes with a full set of metric and standard.

Oh we gonna send it! Cant wait to see how fast this one goes.

Turbos, superchargers, and nitrous is coming.... just trying to get some of these easier builds out of the way first.

No issues as of yet, but I plan on getting a new cam soon, so I do a break down of the engine and see how everything looks now that it has hours on it.

Yeah, it aint bad and I am sure he could make them point back if you wanted.

Hopefully I can get it dialed in and get some video of it running soon.

I think you are supposed to oil them... but this guy aint got time for all that. Not much dust out on the river for me to worry about.

@@SendItJonBoats it helps with water as well

I want to do an alcohol motor soon. Got to get this one figured out first and see where it goes from there.

22hp minimum!

yes I am running an electric fuel pump. I just left the hoses from the crank case and let them hang

LMAO yeah that muffler is freakin awesome.

Sweet! YEE YEE!

bigger is always better. They do not have a lot of aftermarket accessories yet but they will after time. I prefer the electric start because I am fat an lazy

Thats a good idea, never tired that.

Thanks Big Rick!

Maybe ebay, or one of the facebook groups.

Working out a fuel issue now. Hope to have it back on the water for a follow up video very soon.

@@SendItJonBoats yes! Love your content btw. Been building my duck boat for a while, lots of good info on your page.

The stock muffler is about as quiet as it gets. You could add an additional muffler but I have never tried that. I wonder if it would choke the airflow down too much.

@@SendItJonBoats yup that is the issue I'm in Louisiana and sometimes I want to keep stealth to get close to gators but I want the power and above all I don't want to hurt reliability,a little slower is something that can be lived with

HOLYFNSNICKERDOODLES BATMAN!!!!! That's a lot of tragedy in one boat. You should write a book about it.

Apparently he has stopped making them because he aint respoinding to people. I will see what I can do to start making them.

@@SendItJonBoats thanks I got someone who nows him personally and he got me is number thanks though but I’m having a problem with my motor we’re when I run full speed it kill but if I pump gas in to it it doesn’t what should I get to fix that. Thanks for responding to me

Yay! I need to get one.

They’re about $200 more now.

dang... what the f#ck!!!! Inflation is retarded right now.

Yes sir he still is. Good dude and I still love my exhaust.

@@SendItJonBoats Awesome. Thanks for replying. Any chance you can send me his Facebook link again. The one attached to the video wasn’t working for me. And when search his name a ton of people came up. Thanks again.

Some people call it China... I call it egg roll land, or the place where all the tools at Harbor Freight are made LOL. I still love Harbor Freight though.

@@SendItJonBoats same here. Some stuff there is really good, like those 10 dollar angle grinders

@@johncarlberg4481 I love my harbor freight stuff, I just got all new Bauer cordless tools and I am really impressed.

Cool thanks for watching.

Got a video all about it...I know all about them. Check out my mud motor review and comparison video and you will know all about it too.

Yee Yee Geaux Tigers!!!!!!!!

Gotta get those politicians out of there. Use that space for some more horses. Besides, it's easier to clean up after horses than trying to clean up after politicians.

Dang politicians got to go!!!! Bye Bye!!!

You are correct Bob.... hate cleaning up after politicians!

34mm mikuni. Works really well so far.

Just did a video on it. ran great once I got the fuel pump issue fixed.

@@SendItJonBoats sweet! Can’t wait to check it out!

LoL. Scooter can't help it that his brain is mashed potatoes... but somebody gotta call him out!

Mikuni 34

That's not what your proctologist told me!

It's just sweating torque

Very good point... It's better when it's nice and slippery from the leaks.

I spent 3 minutes in the video talking about where I got it and left a link in the description.

It's pretty good. Like dipping a twinkie in hot sauce!

I almost said it was .875 ugga dugga but wasn't sure if everyone would know what I was talking about.

@@SendItJonBoats bahhaha, next time lol

Yes... without Amazon my world would melt, the planets would be mis-aligned, and aliens would transcend to the rivers of earth and turn all the fish into cross eyed albino squirrels with mermaid fins! So yeah go buy some amazon products so I can make 3 cents.

@@SendItJonBoats no dought it would

Yes, I talked about that in the video toward the end. Aftermarket cam will come later.

@@SendItJonBoats sorry I missed that. I’ve got all the parts I need except the cam. They’re saying mid summer. Getting my float pods welded on today. I replaced my 13 hp engine with the 670, and I installed Harley sportster pipes on mine and took the baffles out. Sounds pretty wicked!

@@SendItJonBoats yes sir. I’ll post a vid soon, getting pods welded on the back of it.

LOL, I paid of my debts at the rape van (snap on truck) years ago... I refuse to get back on there now. I buy all my tools from Harbor Freight because I am cheap LOL

Anything is doable once!!! I would do it. Freakin send it and send me some video.

👍

He didn't. Stock flywheel

@@SendItJonBoats Thanks for the info!

Depends on what you want done. Contact me with what you want chris@tbnoutdoors.net

Gotta laugh sometimes... especially working on boats because they will drive you insane.

Thanks
