I have a 1397 in my bike right now and it made 200whp on c110. The head gasket went out so iam pulling the motor out to fix the head gasket. I have another thread posted as iam thinking about doing a gen 2 crank. But I might just upgrade the cams I have now and bump up the compression. Right now I have mega cycle cams intake is 397 lift with 248 duration and exhaust is 360 lift and 252 duration. The head is ported with 1 mm bigger valves. How big of cams can I run? Would be worth upgrading?
