Engine rebuilder Vey de la Cruz told me something awhile back that often doesn t get mentioned in these discussions: You re not just seating the rings......other parts like the tranny and cams also get broken in. He recommended what the factory says plus varying the RPMs. Bogdan [Non-text portions of this message have been removed]

I got my tires seated properly, inflated properly, everything looks good. Get on and ride and it still is uneasy. If I let go of the bars the bike pulls hard left. It almost feels like your riding on two flat tires. Any more ideas? I'm takin it in to the place that mounted the tires tomorrow to see if they see anything. Worked fine before they put on the new tires. Paul Christopherson [Non-text portions of this message have been removed]

I'd put the bike up on its center stand. Weight the back end first and check the front tire for free-wheel spin and play. Missing spacers or bad bearing can cause this. Then weight the front and do the same in the rear. Again make sure ALL the proper wheel spacers are in their PROPER position. Next, weight the rear again and bring a string from the wall/carcass of the rear tire to the front tire--do it on both sides. Then get some straps (tie downs work well) and secure the handlebars at the proper alignment. If it's out of alignment, use the chain tensioner nuts (loosen the axle) to get the proper alignment. Then once you verify it's properly aligned, use a dial caliper or figure out something to check run-out (side-to-side wobble) and dishing (tire tread roundness) and any anamolies. Repeat with the rear tire. Out of balance will not cause what you're experiencing. Either your brake(s) is stuck, tire(s) is not properly mounted, you're missing or have improperly installed spacers, etc. in the axle assembly, or a seriously (doubtful) defective tire (s). There's nothing more to it than this, so no need to contact a rocket scientist. Seriously, compare your axle components and make sure everything is in its proper location and operating properly.
