well im on a budget and couldnt modify the frame...i guess i could take it oput but i still am so confused on gear ratios. whats the fastest speed and ration i could use if i removed the governor? would i be able to ditch the jackshaft? cust i would only use a bolt-on-the-engine kind and i cant find one for the 212cc

the AGK bolts on to all the predators
if you dont have a good budget i would think twice about a 212cc build or at least take your time with it because you are going to have to make/modify a lot of parts if you want to do this if you dont know what you are doing real well you will hurt yourself with this engine

idle is always around 2200 and max is 5500 rpm with stock internals you need a tachometer

Hey, excuse me, so i recently removed my governor, and i was wondering if i just do about 5000 rpm without upgrading any other part like freewheel, piston rod...... Is it ok to do that? please respond!!!

Hey! Just checking in with my 150cc GY6 fat bike build. I am beginning the final stages with doing my gearing. So far I have (on paper) a 5:1 (12 on the clutch and 60 on the axle) gear ratio on a 26 inch drive wheel. I intend to mount the rear sprocket to where the rear disc brake rotor is now to avoid pressure on the spokes. I will still have and use the front disc brake. What do you think about this ratio? Will it eat up my centrifugal clutch? I think the max rev is about 7000. Questions? Comments? Concerns?
