When i use the axle nut adjusters I can get the belt to clear (barely,) but then there is resistance from the brake as the tire is not really perfectly straight (which I assume would make the bike track poorly anyway?)

I just put a Dunlop 250 on my '08 Rocker and it's SO tighter between the tire and the belt I can't believe it.
There are several posts where other Rocker owners claim to have used the Dunlop 250 on a stock setup with no problem.
I have a very, very small gap for clearence right now but it's really too tight for me.
Can I run a spacer on the pully to move it over a little? Is there then a shorter replacement spacer for the large, single spacer that's currently on the left hand side? Is there anything else I would need to change if a pully spacer was added?
Thanks.

So JD, I was thinking that it needs more spacer on the left side to push the pulley more to the right (brake side)? The pulley needs to be farther away from the tire (a pulley spacer) then the wheel more to the right with the rocker spacer plus another 1/8 or so (so the belt clears the tire?) Thoughts?

it seems like the tire and the belt are so close in your case that when you ride that thing and the tire expands due to the heat you're going to have some problems.
As far as the spacers, i'm not too sure man. i would think that you wouldn't want to mess with spacing on the back wheel without matching it by moving the transmission as well, that belt has to track straight from the rear sprocket to the transmission.
i'm sure someone on here with a little more experience will chime in.

I was thinking a spacer between the pulley and the wheel would push the pulley further away from the wheel/tire and give me more clearence.
Now that I think about it, the axle spacer on the left hand side wouldn't have to be any shorter because it passed through the pulley to the left hand side wheel bearing. So the wheel would be in the exact same position in the swing arm, the pulley/belt would just be pushed over to the left and away from the tire.
Does that make sense? Can you just move the belt pull over to the left with no adjustments or modifications to the drive pull on the transmission?

I think I'm going to call exile tomorrow and order up their belt drive with a chain rear. Guess the motor work will wait until next winter now... That will sove my problems.
AS far as spacing goes. I think that the drive pulley needs to be aligned with the transmission, but you could achieve that with a pulley spacer, and an equal wheel spacer. So the pulley gets spaced out from the wheel, and the wheel gets spaced over the same amount in the opposite direction. This moves the tire over, but leaves the pulley in place? I think you can probably do a 1/8inch over without screwing up the ride much but there are tons of experts on here that can answer that one.

The front pulley for the drive belt is quite wide. Spacing out the rear pulley is not an issue. You just need to determine how far out it needs to be spaced to clear the tire. Upper and lower belt guards are sometimes in the way as well.
