Yamaha G9 rev limiter
My G9 goes about 30kph.. I've already bypassed the governor.
It accelerates well but when it reaches this speed some sort of limiter kicks in and cuts the revs, then it slows a bit before the revs increase again.. This is annoying as i know its got so much left in it! so is there any way of removing this limiter? or does anyone know where to find it? Also i've read posts which say this is bad for the engine if you go flat out for too long so is there any other way of increasing the speed? |

Re: Yamaha G9 rev limiter
G9's do not have rev limiters. The G2 has one and there is no way to disable it.

You might take the primary clutch cap off and check the weights. I've seen loose/worn out or broken weights cause the "reving" problem. Good luck Dave

Max speed on a stock G9 (with the governor completely bypassed) is around 25mph. Average is about 20mph.

Re: Yamaha G9 rev limiter
Bypass the governor if you haven't. Hook the pedal cable directly to the carb. and do away with the small cable coming off the governor (completely bypassing it). You'll have to adjust the cable so the carb. throttle completely opens and (for sure) completely closes. You can also get a jet kit and k&n air filter for it. Another thing, if you can weld, is take apart the muffler and gut it. They are very restrictive. All my Yamaha's, the first thing I do is bypass the governor and install the spring/spacer only torque kit. Then I just usually leave them that way. If you could get ahold of a G16 engine, mod it to fit in a G9, then you could hit some high speeds up around 32+. But as far as these little mods go, bypassing the governor is about the biggest jump your going to get for speed. After that, big blocking would be the next BIG step. I advise running a good synthetic if you bypass the governor. I run Mobil 1 10w30 in mine. And never ever ever ever put any thick oil addive in your cart. It uses a splash system to oil and oil additives will not splash (so to speak). You'll ruin your rings quick.
