On the TE and WR models made in the last 5 years or so, is there any differences in the rims, hubs, wheel spacers, or brake rotors? I have 3 sets of rims, one set from a WR250 (06 I believe), one set from my TE450 (05), and one set from my TE 610 (09). I put the wr set on my 610 and it chewed the crap out of the sprocket... everything is in place... I did replace the 48t sprocket with the 45t rear, but was sure to evenly torque it down... The sprocket looks like it sat 1/8" over too far. It is a ground down (evenly) on one side... I'll get pics up later if it'll help. Anyone?
Actually in 2008 when Husky came out with the new frame is the first time I saw the spacer added to the rear hub. The new frame WR 125 uses this as well. The WR 250/300 still have no spaced hubs. I am not sure on the 610. If you look at the sprocket side there will be a little ridge where you can see they added a 5mm spacer to the rim. If not that check that your wheel spacers are the same length.
