250-500cc 09 WR almost finished, 2 questions.

Hey guys, been fixing up an 09 WR 250 and am almost done, just two probs. 1st, the rear brake rotor is loose. Bolts are tight, but it can move about a bit. Been wondering what the rattle was and just found it. Is it meant to be like that?

2nd, the factory odomiter has started adding '000 of km to it by itself. Speedo seems fine, but km have gone for 2000 to 5000 in about 100 km, any ideas? Thanks.

The rear rotor is normal,the speedo's are junk on them,toss it and get a trailtech.

Yup, the rear rotor is most likely a floating rotor, and they do have some play, that could also cause some rattling. Totally normal. As for the Comp, no idea's sorry man... However, trailtech does have some good computers that are really capable of a lot of things these days. All depends how much $$ you wanna spend

This is why I love this forum. Thanks guys, have a trail tech X2 light and the comp has been on the to-do list for a while, now I have an excuse. I have tried hard to make my bike unique (murked out, almost Harley style 2-stroke for almost all on road use) and you guys have helped heaps. Thanks again.

I know it defeats the purpose of having a floating rotor but I added a few rubber O rings from the hardware store to stop the rotor from rattling as it was driving me crazy.Two years later,no rattles and the brake works fine.

Thanks, the rattle always worried/annoyed me, thats a great idea, thanks.
