Any of the racers here figure out a good way to relocate the rear caliper so it doesn't have to be pulled for a wheel change?

I never pulled my caliper for a rear wheel change. Lift bike, loosen axle, remove belt from rear pulley, remove axle, remove wheel. The wheel comes off and goes on for me without any problem related to rotor and/or caliper position.

Point,

I don't know how you do it. The caliper causes me a lot of grief if I try and leave it in place. Between the caliper/wheel and the pulley, I can't get the rear wheel off without pulling the caliper.

I'm on a 2008 model -- I'm under the impression the issue was fixed in 2009.

Nope, cause i have taken my rear off with out removing the caliper, i just lifted the bike. pulled axle, slid the belt off and then i angled the wheel slightly to get past the caliper.

it can be done my friend.

Interesting. I'll have to try again. I've tried before and I always end up with the wheel jammed up against the pulley on one side of the swing arm, tire against the other, and still not locked in the wheel well with the caliper.

The service manual specifies the caliper has to be removed, btw.

You guys are on 08 bikes, right?

Yes, I am on an early '08 also (Dec. 07). I saw the caliper removal instructions in the service manual, but it just so happened that I was reading the day before about others doing it without messing with the brake.

I am not rushing like in a pit situation, but mine comes out without much effort at all. If I recall correctly (it's been a couple months), I never really tried much of an angle to get it out. I think I kept it mostly straight, and just wiggled the wheel a little while pulling it back.

I have tried this as well and was not successful. If I was to let the air out of my tire it looks like I could manage it though. Maybe its the 190 vs the 180 tire that is making it more difficult for me.

I am also using a Pitbull stand and there is virtually no clearance between the Pulley and the stand support (maybe .250")

i have NEVER taken off my rear caliper to remove the rear wheel on MY OH-EIGHT

move the belt out of the way, and it slides in and out like a glove.

obviously you need to take your time and study it more... taking your time is important on any matter of maintenance on your bike!

So, I was able to figure this out.

I'd say it's a bit of a tricky operation. There's lots of chances to grind the pulley against the swingarm, or the caliper against the wheel.

Also, the height of the wheel is really important. You want it at almost "run height". Any lower, such as what happens when the bike is on a stand and you pull the axle, and things bind up.

I put blue painters tape on the back of the caliper and went slow, wiggling and jostling along the way.

I couldn't recommend this for someone incredibly particular about the finish on the bike, but since mine's a track bike, geez, I don't care! I suspect cosmetics are the real reason the service manual specifies to pull the caliper.

Thanks for the help guys.
