Didn't turn out half bad. Just need to make one adjustment to them. Instead of 1.XXXX when I was offsetting the exhaust mount hole, I 0.XXXX. It's off an inch. They entirely replace the factory steel bracket, but will retain the factory exhaust mounting location, will work with the stock brake line as well. Going to use a pressure activated banjo bolt brake light switch to retain the light. Didn't turn out half bad for first pass at them. I've been building 250/350 rear sets for right about a decade, figured it was time to venture into the 400 as well.

Do not underestimate the power of a two-stroke.
