I am about to hit 1000 km on my MSX and on the way home I notice a huge decrease in power in 3rd and 4th gear. With only 1 km from home I manage to get it in the drive way and the rear disk is smoking hot. I was on a 40 minute round trip bike and a 10 minute trip from work an hour before. Hopefully when it cools down it will release. But when I try to manually use the foot brake it does not move the pump. I do have aftermarket rear sets on and I power wash it every week. Any suggestions?
