NOS_350x Posted April 20, 2010 Report Posted April 20, 2010 Any ideas what the problem might be? Im going to continue tearing it down right now. Just curious if anyone elce has had the head look like this? Plugs where not what was ran in the bike, they got put in right before i tore it apart just to check the spark. Quote
someone82 Posted April 20, 2010 Report Posted April 20, 2010 I have had a similar looking dome when one of my cylinders wouldn't fire. Tore almost the whole motor down until I discovered the ground to the cdi box was loose. Quote
Kingsley78 Posted April 20, 2010 Report Posted April 20, 2010 Kinda looks like the plugs wernt hot enough but you would see that in both domes. Maybe one carby was out in its jetting. The left one looks sooty, like its rich but im no pro... Quote
Bill Posted April 20, 2010 Report Posted April 20, 2010 Post a pic of the top of the pistons,I'm curious on what kind of wash you got on them. Quote
pr0blumz Posted April 20, 2010 Report Posted April 20, 2010 I had the same problem. A set of bad reeds on the that side was the cause. Quote
