it's my guess the bar clamps shouldn't really be touching the top triple yoke's surface or you'd get all the vibrations back into the bars from the yolk. The bushings are to allow the bars to effectively 'float' by isolating the clamps (bolts) in the rubber tubing and therefore reduce the vibes. If you've got a depth gauge I'd measure the depth of the hole where the bar clamp bolt passes through and make sure the new ones are the same as the old in depth. As for pressure to insert the new sleeves, I would guess the old ones had a better 'tolerance' fit than the new or possibly had 'corrosion bonded' with the bush sleeves being steel and inserted into alloy. It's too late now, but I might have mic'd the o/s diameter of both the old and new before fitting too.
