Black Spooge
Pat said 2006-12-21 03:11
I have an 2002 CR 250 with an FMF SST pipe and Q silencer. The bike runs great. However, whether I´m on the track or the trail, I get black spooge out of the silencer running down on the swing arm. I mix my fuel at 40:1. Has anyone else had this problem and found a solution for it?
