Can anyone give me the Vipers timing Curve? Also does anyone know how many CC's the Cases are?
 

Per my Yamaha service manual. Ignition timing (B.T.D.C.) 18 degrees at 1,500 RPM. I have cyclinder head volume with spark plug? 22.9-23.5 cm3 (1.40-1.43 cu. in) cylinder bore size (70.500-70.520mm(2.7756-2.7764in)
 
if noone else digs it up I can get you the cc for the SRX case, but the crank is different so the reading will be different aswell. I don't know if I've got a viper crank kicking around to measure for you or not tho, I don't believe that I do.
