Hey guys, well I bought what I believe is a 1980 xs400. When I bought the bike it was just a big pile of parts.this isn't my first bike so I figured I could get it running, but this bike is giving me Hell. I'v gone through the carbs with carb cleaner 4 or 5 times now and it is squeaky clean the plugs have been replaced and have a good spark the bike has good compression. If I spray starting fluid in the carbs I'll get a few backfires but that's about it. I'v gone through everything I could think of. It is a bit cold at about 38° that might have somthing to do with it but my yx600 fires up fine at this ttemp. I would like to hear any ideas
