HI all- I bought a used 99 WR400 with a series 1 E-series exhaust. I bolted it on today and noticed the rear brake reservoir was melted and distorted. I have about a 1/2 inch gap between the pipe and the reservoir. Anyone else have this problem? Solution? I gave it a quick run around the block and noticed the reservoir was leaking. I planning on fabbing in a heat shield with some reflective tape, not sure if it will work. The bike seems to have a bit more pep with the pipe on though.
