Just out of morbid curiosity, how exactly were you expecting a full race cam to behave at 2000 rpm?

According to Kent Cams spec it has 12.19mm of lift, 313 degrees of duration and a power band of 4-8.5k rpm.

I am surprised it runs at 2k!

ahh thanks for that. thought it would be pointless asking on here......

I'm with you ! something set up like that will be a pain in derriere under 3500

it does run very well to be fair i thought maybe it may have been down to the cam but i do need the carbs setting up properly. ok back to the drawing board....
