I just finished installing a Mcleod street twin, Al flywheel, and new pilot bearing. The clutch engages and disengages very nicely and the transmission shifts fine.

I am getting a slight whirring noise under part throttle, especially in 4th gear. It sounds very similar to the mild whirring noise you get from a stock T56 from ~800-1200 rpms, except that it occurs most noticable around 2k rpms and especially in 4th gear.

Has anyone else experienced this noise?

A different harmonic from the wieght of the street twin maybe?
