CRG SP97 100cc engine

Does anyone have any experience running this engine? Do you know what kind of aftermarket carb one can run? Reliability, drivability? Any assistance is greatly appreciated.

It’s a JICA engine. Like you said, 100cc. Piston port motor. They typically ran a walbro carb, it baroni and hubchen made carbs for the too.

JICA was the top class for junior drivers from 12-16 y/o from around 1993 until 2006. Don’t let the fact that it was a junction class fool you though, they are pretty peppy. More power than a HPV/KPV.

Reliability wise, they are pretty solid. The internals are of higher quality than a typical KT. In racing conditions they would be spin to 17-18, so for lapping you can run them 16k all day.

James how would I find the size of the carb requires, correct ignition coil etc?
