I just did a compression test on my wifes banshee (this is not bansheebabe04) and i got 145 in both cylinders with 19cc domes. im at sea level or close to so im sure it should be higher but is a top end rebuild nessesary now? thanks for the replies. by the way i contacted the guy thats the work on my yfz and he said i dont need to run race gas cuz of the low comp.
