I just got a 98' Mojave but it lacked compression so we tore it down to put rings in it. On the inside of the head where the cams are the was 197 wrote in a white marker, also on one of the cams (I can't remember which one) it had 197 on it. It's also .50 over with a wiesco piston. Is 197 a cam grind or maybe it was shaved or something like that. Anyone know what I might be talkin about

 

I just picked up an 01 Mojave so I haven't been into the engine yet. I can't tell you about the 197 but if you check out these guys I am sure you will find the answer. http://www.cycleworksracing.net/mojave.htm
