Predator engine bypass the governor for racing

[@nateswanson]

Thanks for this! I'm not a mechanic at all but wanted to get a little more juice out of a new Predator 6.5hp for my kids. Before the modifications, our steel frame go-cart would max out at 9mph. After following these instructions we just hit 26mph! Definitely enough speed for beginners - thanks again!

[@doodizatahemi9544]

A gearing change can get you to a good 35 or 40 after this bypass. For when they get a little older lol

just what im looking for thanks ;)

[@paulsimon365]

Would this work for the vertical shaft engine also? I need to replace the engine on my Ride On Spreader. It needs to operate a centrifugal clutch like a minibike/gocart. Thanks for any help.

[@chuckvenable4409]

Thanks, but I need my governor in my application. Matter of fact I need it to respond much more quicker than it does. Been experimenting some but still moderately slow at responding the way I need it to. Any suggestions would be of great appreciation. I understand that at engine rest , throttle is fully opened till engine starts in which the governor pulls back on the throttle slowing the engine to a preset position . In my case at 3200 rpms. Once a load is applied depending the amount of load, engine just pulls down and governor doesn't respond for a few seconds . If it's a lite load, governor doesn't respond at all to increase engine speed back to 3200 rpms or at least close. My engine is the predator 670cc V-Twin 22 hp. Other than this governor issue, engine runs great.

That music in the background though 🤣

(TIP'S) note if you filming from your phone and i know you are! turn your phone sideways to get full screen in your phone recorded video's ;) it works for mine should work for you too

I think he wanted his video to be a Short. Shorts have to be under 1 minute though.

Do you have a shop or work on go karts?

[@mogegeh]

Good stuff, thanks for this. Would I need to change the flywheel at some point?

[@jordinmichael3298]

Kinda unrelated, my predator's valve cover is like a hexagon shape. Does this mean it's the hemi or is it the same as yours?

[@lukelevesque03]

Hexagon shaped valve cover is a non-hemi.

[@squadupadventures4670]

Would this be the same for a 420 predator

[@fish_R_stinky69]

Yes

[@tomsmith3987]

Not clear information im still lost

[@reddevilent.1587]

So you leave the governor installed but you took it off?? I'm confused! I've seen so many videos where they have to go inside the engine to remove governor. I'm just trying to figure this out

[@DavidRodriguez-fn4yn]

RedDevil ent. I think what he’s doing is bypassing the governer so it wouldn’t have the exact same result as removing the whole thing. Just a guess tho

[@matthewarnspiger632]

well, yes and no. the internal governor is a plastic gear with weights in it, as the rpms increase the weights push something out and it pushes the governor rod from going 100% throttle. so I you just bypass it you have the same effect as removing the governor but if you just remove the governor gear inside the engine you wont have to mess around with any other throttle linkage stuff.

[@dylanhyde2668]

Can this same method be used for the 420cc?

[@fish_R_stinky69]

Yes I believe so. All of the Predator engines under 459cc have the same design.

[@shawndudeman5499]

is there away to not completely bypass, but to bend it or do something to set the governor at a specific max RPM...?? acting as an adjustable rev limiter?

[@Deucealive75]

In the video at 2:11 he sets the throttle assembly out of the way. On that part there is an adjustment screw. You can change the stock RPM with that screw. Back it out for higher max rpm and turn it in for less max RPM.

[@shawndudeman5499]

Thanks man, that was a good explanation and was exactly the info I needed.

[@Deucealive75]

@@TheEliteAnimalOn the throttle assembly. On some new mini bikes like the Coleman they are welding that screw so it can't be adjusted. People are cutting the threads off with a Dremel for more rpm.

[@joshschroeder5879]

I race mini bikes and do small engine repair for a living and build fully after market engines from bone stock to racing machines . You can't leave that arm and gear in there it hits the Rod gotta take it out and put a self tapping bolt in there

[@codysett1]

Josh Schroeder I think I watched this video and then learned what your saying the hard way. The engine wouldnt run correctly and made a weird tapping then the next time I went to pull it to start it, it stopped it dead in its tracks, it wasnt siexed like I can crank it backwards to a point but it would crank normally then hit something and not move anymore, is that the rod hitting the governor gear? How would I fix that?

[@joshschroeder5879]

codysett1 take the side cover off cut the govnor rod in half and pull it out of there and put a bolt in the hole that arm was in .

[@Deucealive75]

Josh. You should watch the video again. Maybe then you will understand why this arrangement will not have the problem you describe. Hint....Springs.

[@I_miss_the_misery]

U build bikes. Race them..I have afew ?.I'm building one..about the cam arc rods, crank

[@Tncoonkiller]

What kind of rpm are you turning with it bypassed like that?

[@doodizatahemi9544]

Valve float will start at about 6200rpm

[@fish_R_stinky69]

@@doodizatahemi9544 The engine probably won't be making much power with its stock camshaft at that rpm.

[@deansmith3817]

Or just use a zip tie does the same thing only difference no time wasted

[@chuccsdj7039]

will the governor gear break inside?

[@CrushingBass]

no, as long as you dont rev it all the way for a long period of time. should be all good.

[@mikebeggs9085]

I would think if you were setting up for race....It would be revved up just about continuously !

[@robspear03]

Yes, yes it will. It is plastic and is not designed to exceed the rpms that the engine is capable of. Remove the gear. Its a good way to learn about your engine anyway.

[@boostedmk5gti563]

U will still end up having to pull the engine apart gear will break apart quick

[@khonky]

Someone paid you to do this?

[@fish_R_stinky69]

No he made it for his kids.

[@khonky]

@Stinkyfishyツ he says right in the video that he was doing it for a customer.... his kids are his customer?!?!?

[@fish_R_stinky69]

@@khonky Doesn't mean he's paid to make the VIDEO.

[@fish_R_stinky69]

@@khonky Its really easy to disable the governor. Its a lot harder to bypass it though. To disable it just open up the engine and hammer off the plastic wheel.

[@khonky]

@@fish_R_stinky69 I am fully aware of removing the governor. I build stroker motors that cruise at 60-65. You did see where my comment was from 4 yeaaaaars ago. Stop talking....

[@libertywagon3197]

And a useless video too! Didn't help me solve anything and wasted my time!

[@kylelevin5855]

This does not remove the govenor, this is just bypassing the govenor arm. The governor gear is still inside limiting the RPM to the governed limit set.

[@matthewarnspiger632]

Not true. if the internal governor has no way of getting to the throttle butterfly it is deemed useless and it cant do anything.

[@DivineMisterAdVentures]

Aaron, that may be brilliant - or it may be stupid. But it was sure poor doctoring - if you didn't teach us why you did any of this. 1) No before & after effect. 2) No explanation of your theory of the engineering involved. 3) No tactical theory either. 3-strikes you are OUT.
