my R1 is a 05 with a 5 valve motor, the 07-08's changed to 4 valves so I think it would be different, however I run 15/45

Last race I was using 16F/ 46R and it was ok. Sunday and Monday I'll try 47R and let u know.

Thanks guys

JC do you reckon it was a little tall or a lot?

47 works better for keeping the wheelbase in check so I'll just tell him 16/47
