I picked up a used WB Series E pipe, for a reasonable price. The clearance between the rear brake reservoir and the pipe is about 1/8th of an inch. I may be able to put a spacer on one of the mounting bolts to increase the gap a bit. I'd like to keep the reservoir from melting, in case I need the rear brake. Also, the number plate is melted a bit on the pipe side - I'll cut the bottom off most likeley. Anybody have a WR and WB series E with similar issues?
