I have seen this company or person selling a 30 or 32 front pulley (new) and a (used and modified) 66 rear pulley.

I want to try the 30 front because of no modifications needed and the fact that its a brand new piece. However Im a bit concerned about the 66 rear pulley being used and modified for a sporty.

I would also like to reduce the rpms while cruising around 70 to 75 mph. My stock sporty iron is smooth up until about 70 then its horribly vibey up until 90mph where it suddenly smooths out again.
