just got my project running as some of you know, took it riding in the snow with a couple of banshee friends ,and it ran realy great , rode it for a couple hours ,the next day took it out again ,it had a little hesatation but then ran good . rode for a little more than started to run like shit , hesitating ,breakin up ,sounds like its runnin shitty in left cylinder ,popin a little bit out back ,and smoking out front of radiator . compression is still good on both sides. working on this thing is getting old fast , any thoughts?
