Just installed new PST 1.03 bars

Its good to know I'm not the only one that close. If I do have the rattle I was thinking of throwing on a torque strap or the mag style mounts from Mancini

I have about an 1/8th also with rubber spool mounts and it doesn't touch.
The trick I think is good condition mounts, and polys even better if you don't mind the extra engine vibration transfer.
