670 Predator Mud Motor | Rebuild and mods for more speed!
In this video we are going to diagnose and rebuild my 670 Predator mud motor that I caught on fire in the last video! We are also going to do some performance mods to get this Harbor Freight 670 Predator running with more speed. Follow along as we install a ton of upgraded parts from Performance670.com and make this 670 Predator roar!

[@nuttyDesignAndFab]

I commend you for not using billet! I think its a lot of extra work and money and the v-twins are already enough dinero to begin with. One issue with the carb: V-twins have weird timing and a single carb/single exhaust often don't resonate correctly, leading to uneven fuel mix & performance between the cylinders. 2 cheap carbs are often better than one expensive one. Same for mufflers, that way you can get each bank to run right individually.

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

[@bob2161]

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"

[@SendItJonBoats]

[@bob2161]

@@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.

[@bob2161]

@@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

An hour of run time and running the heck out of it! What happened to break-in time? I went the recommended 20 hrs, it never hit more than 3/4 rpm. Nice warm ups Pryor to working it reasonably! Now I work it hard, no fires or issues!

[@SendItJonBoats]

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.

@@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!

[@heathdaniels8979]

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

12.5 hp gain just switching out the oil filter lol

Sir, can you please on the next time you use a growl as a reference of torque assimilate a number based on the intensity of the growl so we can make a better reference to try to replicate it.

Been so long I don't even remember. Contact Jeff Clines on Facebook and he will get you squared away.
