259e cam concerns
So, I just had my bike re-tuned on the dyno and really just wanted it to be smooth.
it has plenty of power etc but down in the normal world 22-2500 rpms it still surges, twitchy and is just ready to be at wide open it feels like.
this is the 103 10:5/1 pistons, (was told it was 10:6-10:7/1, cnc ported heads, valves, springs, injector, 58mm throttle body, 259e cams. on the tune we spent 4hrs smoothing it out best as possible.
Any body else deal with this? I love the power but its getting to the point I don't feel it is practical in the smooth riding sense. Should I change pistons to lower compression or change out cams? Any thoughts would be great. thanks.
ps, cranking compression was 120 front and rear
I'm not a Dr. but i'll take a look
