Mikuni carb question with stock semi stock engine

[TonyMontana214]

i have a 212cc predator. governer has not been removed, exhaust header, and now potentially a mikuni.
i see how the install is done but there is one issue. what do i do with the governere rod and springs that connect to the original carb after install the mikuni? can i just run the engine with the governer still installed

With those carbs you can't really use the stock gov, if you don't change your valve springs, you'll be good without the gov..the rod will still be safe aswell.

Just leave the return springs on the levers. I've been running mine this way for months.
If it blows I'll post here to say it's a bad idea, but untill then no one had proved otherwise.

Now if the external arm is removed or left unsprung you will have a problem.

i still down understans how thr engine will blow up by just adding a better carb? also can i remove the gov and still run a torque converter or is that a no no?

 

[mckutzy]

Ya remove the gov and use a TC... good to go...

 

[Ebrownie]

Torque converter has nothing to do with engine longevity and performance. Adding a better carb won't blow it up; what blows it up is running it at too high of rpms for too long and throwing a con rod. If you decide to remove the governor, keep the stock valve springs because valve float limits your rpms to a little over 5k. This is still ok for the stock rod and flywheel.

alright so one more question. if i remove my governer, will the higher rpms cause me to eat through belts? thats whats keeepjng me from doing it honestly. ill do the billet fly wheel and rod but i dont want to eat through belts left and right

 

[Whitetrashrocker]

If properly alighned. The belt should not be a problem.

If higher rpm's are what your after.. A good cent clutch will do nicely..
Any of the racing versions with friction plates, work great, easilly rebuildable, and very customizable aswell.

well i want higher rpms but i still want to climb hills when i take it trail riding

 

[Scout]

then you'd probably want to sty with the torque converter if you are climbing hills.

AS far as the engine blowing up, that comes from higher RPMs, which without the governor will be limited by the valve springs. Others have said that if you leave your stock valve springs in you will be fine.

Now that's some of the best info i've got in awhile thanks! This thread shook out a lot of opinions ive got elsewhere. What I woulda done 40 years ago as a kid with dime a dz engines, click to order parts and forums im not sure. You really have to experience that to grasp how easy it is now.
