While giving the Paso a look over I found that there is side play in the rear wheel. Before I pull off the wheel is there anything I should know about replacing the rear wheel bearings? Is it just a matter on knocking them out like I do on a Guzzi? Then tapping back in?
On the plus side, the bike started up and ran nice on the short ride I took. Did not go to far do to the loss rear wheel.
Also can the front brake rotors be grounded down? When braking hard I get a lot of vibration.

Well I answered my own question, they tap out, no problem. Looks like the sprocket bearing is also shot.

We didn't even get a chance to jump in here!!

Glad you got it figured.

The original front brake rotors certainly can be turned down. I had mine done about a year ago.

I order the wheel bearings from a bearing dealer in Hartford. $28 each for the RFKs which was the only brand that had the right size. Ouch, I paid $8 for per bearing for the LeMans.
I'll check on having the disc turned.
I'm thinking of selling the Paso now that its all sorted. I always end up doing this. I'm thinking of getting back to owning one bike. Maybe a Buell Uly if I can find a used one in the locally .

Don't sell your Paso. You will regret it. I had a 98 ST2 for 5 years and had sorted out all of its little ills, then sold it to get an ST4s. I still can't ride the new bike as well as the old bike, and I'm constantly sorting out all those things I did over the past 5 years on the older bike. Too much time wrenching, and not enough time riding. Now don't get me wrong, I love to wrench as well as ride, and if I didn't, I would just buy a Honda and accept the ride for what it was. But that's just not the way of this tribe. But there is a balance, and I have once again stepped onto the wrenching side of things. Bad timing with the weather so lovely lately. I'm just riding a half finished project bike all the time.

Cheers,
