if i was to describe it, it is a significant change in the
way the bike feels, it tends to pulsate and vibrate more than it did becoming progressively worse as the rpm increases, perhaps the flywheels are now too light for the compression the motor now has, the bike runs perfect by the way, just...
Just for the record, all parts went back into their previous locations, all parts were marked and assembled as they came apart, cylinders were removed and shortened, pistons re-ringed, cam change, thats it.
it is a stroker with S&S 4.5 inch stroke flywheels, like i said nothing else was changed apart from the comp ratio and cam, the motor was together a few years before the change and was fantastic, it was balanced when it was stroked and vibration was never an issue. Now the vibration gets...
I have an old Harley, recently i upgraded the cam to a performance cam with extra lift and duration. I increased the compression to get the static compression back up to where it needed to be to get good low rpm performance (170psi).
Apart from the cam change, the only other change was to the...
