C12 is for motors less than 15:1 compression ratio, 108 octane, C14 is for motors with more than 14:1 ratio, 114 octane.
Is he running that much compression to require that fuel?
I am not sure what hes running for comp. I know I am I have to run c-14 or more with my bike. He is having some jetting issues and just recently switched from the c-12 to the 14 and was thinking it might be the diff. in fuels. We both have been tryn to get our bikes dialed in before this sundays race. Its gonna be a showdown the past few years me & morse250r have been goin round & round its right down the line within inches every pass. But we have become good buds along the way so its all good. I gonna git ya Morse...

Nothing wrong with that...
Myself, JT, Shayne and Roger all have friendly competition too...

Last one in the 3's on their own bike buys the other 3 a case of beer...

So far...NONE of us are there. I got a feeling Shayne might be the first one. JT and I are gonna be up a creek without Jockeys...LOL....

I might have to sell the bike to a Jockey for a pass or two, I haven't looked over the rule book that closely yet...LOL...
