Can the hub in the wheel be offset by 10mm by tweeking the spokes ?? (I'd take it to a shop for that !) or is there any other surgestions ??

i had the same problem with my cr500 motard with the 160 rear tire,i laced the rear wheel up slightly offset,that and washers behind the front and rear sprockets gave me some room although it still hits at times,i still shaved a little off the tire as jam said and now it rarly hits.if you do space the sprockets out watch the frame clearance to the inside as the chain may hit there also.

Cutting tires is a pain, but you might be able to find a shop that has a tire profiler. I used to work at one that had one. Changing the offset of the wheel is also a solution.

My 98 wr400 needed loads of offset. I just kept turning the spokes 1/4 turn at a time until it cleared. Must have moved it a good 6mm. Then I cut the edge off the tyre by about 5mm anf ground it nice and flat. It still kisses it, but not too bad.
My friemds 99 had no problem as the swingarm and wheel are different on post 98's. Both our bikes have 150 section BT96.
As it comes from the builders the centre is about 15mm to the right than the MX wheel (I took off my rear shock and played with the wheel/subframe relationship), but this does not affect handling. I can grind both pegs on the floor with ease on fast corners, swaps line fine, corners same both ways. I check alignment of front to rear wheels with string line & ignore the adjuster marks, the chain ends up ever so slightly out, but the wheels are equal.
If you space out the sprockets your chain guides will be out of line and this will cause problems. Plus how do you space out the front sprocket??

On the 150 tyre is any shaving required or should it just pop straight on.

What kind of speeds do you get out of the 15/46 combo? I have 15 and 16 fronts, and a 48 and 42 rear to play with. Problem is, I need to shorten the chain to run the 42 rear...Decisions decisions.

*** Jam *** I get about 93 MPH out of the that combo WFO, the best part about it realy is that the ratio is just right for typical tight canyon riding and 1 or 2 downshifts will get the back end comming around with little rear brake modulation, still need to feather it (rear brake) a little to get it hacked at lower speeds but from 5th to 3rd for example it steps out really nicely to square the corner
