the timing camshaft is the same as that recommended kentcams (2,28mm /106°)
I contacted but did not respond because kentcams closed for holiday

can someone help me?
sorry for the english but I'm Italian

to me it if it is running MBT or DBL in that speed range, then it would indicate a inlet/exhaust pulse tuning issue. Perhaps try a different inlet/exhaust combination which should yeild some better results.

What is the length of the runners on the c2r2 inlet manifold?

off topic, where in Italy are you?

mbt dbl? WTF? :)

runners are original length but were joined at the head

Turin :y:
