The person who owned the bike before me started doing a bunch of work on it and never finished. So when i got the bike it had been sitting for a while. At first it would fire at all. I threw some new plugs in it and now its firing on 2 cylinders (If your sitting on the bike it would be the 2 right cylinders that aren't firing). I noticed none of the emissions stuff i believe hooked up could this cause any problems? They bike is getting spark, and i put my hand over the cylinders that weren't firing and i could feel it had compression. Just wondering if anyone has any suggestions before i start tearing in to this thing too much. The carbs were just rebuilt also and didnt make the bike run any better.
