SVBiker's bike is sufferring from same symtoms after a crash. Did you also crash your bike lyley? We replaced front forks, bottom Yoke and shaft, new front rim, new spindle and new right hand side disc which was nackered. I've checked the other on a late. Its ok. What remains are the frame and the rear swingarm. Biggest candidate is the rear swingarm. Any idea how to check that one out?

yeah i hit a kerb at about 70Mph
problem is that the swing arm and frame are obviously desighned with milimeters in mind, and you cant really do a bodge on them, i really recommend getting them both checked out, if you search " Oh i get it SV's dont like kerbs at 70MPH " in the pictures folder you will see my crash

An update on my brother's problem. I put two 8 foot long 2xhalf inch aluminum sections running next to the bike, sitting on 4 inch blocks at each end and tied to the rear tyre with a piece of string. The front tyre was then centred in between the front gaps. I found that left side had a bigger gap then the other so adjusted the rear wheel so that I ended up with the same gap on both sides of front. Hope this is making sense Voila!! Problem solved, The bike is now running straight and feels great.

Funny thing is, when I checked out my bike it was worse! Seems like the square washer pieces at the rear adjusters don't have their inside hole an exact fit to the rear stud so some play is there. So comparing the rear slits in the swingarm ain't enough. I've sorted it out and now I'm a very happy man.

Right on Zunky!
That is the only certain way of checking font/back wheel alignment.

i use the string method.
