I read online that the stock cdi "limits" the rpm to keep the speed down on the little lt. Is this actually true or not? Has anyone tried to use a different cdi? or are there performance cdi's out there? Does anyone know what the stock cdi curve looks like?

 

There is no rev limiter on LT80's.

 

that is good to know. thanks does a little advance help these motors out a bit?

 

Prolly not for a stock motor. I advance the timing a smidge when I build my National motor.
