If the governor is back on the cart, check to make sure the throttle is opening all the way when the pedal is pressed. Try it with the key off.

Thats how I set it after the build and reset it again this morn. Maybe the governor is doing its job and I'm not realizing it, gonna take it for a ride without it tomm. and use up the break in tank of fuel to get to the more lean and try it that way. Any other suggestions on getting more speed safely? Not a whole lot to adjust on this thing.

Also I modified the exhuast The old muffler was blown out the bottom so I cut the Flare from it and welded it to a good Chinese moped muffler, the connecting pipe for about 6 inches to the muffler is only abut an inch around instead of the normal size would this or the muffler have anything to do with power loss?

I can tell you that it wasn't the governor being disconnected that took out the motor. That motor can rev to unbelievable rpms, I don't know the nature of the failure, but if you disconnect the governor, there are other things that need to be done to keep from grenading the motor. Very simple stuff.

The exhaust is key to a 2-stroke running good. If you are just looking for stock 12mph, the exhaust really doesn't matter. If you want more speed and more power, the exhaust is critical.

Great stock speed is 12mph? Thats what I hopeing to hear carts probably running perfectly then it just seems slower to me than other toys ya know lol?

That's what the governor is set to at the factory.

Any fine tuning adjustment recomendations after this rebuild?

It depends on if you plan on running the governor or not, and what you are looking for out of the cart.

Honestly just stock speed most of the time but wouldn't find to see if there's a quick few things or so to get just a little extra pep out of it sometimes without risk to the engine.
