This is most definitely a carb dirt problem, remove the carb and blow it out with compressed air and use carb cleaner to clean the jets and internal passages, then blow out the passages again, compressed air is a absolute must have, also it would be a good idea to remove the gas tank and make sure you didn't pick up some dirty fuel, it only takes the tiniest bit of dirt to cause this problem.

    it is very easy, just disconnect the linkage and the clamp to the rubber intake tube and off comes the car, the jets and p[assages are cleaned through the float bowl, very, very simple job. I have done many 4 carb setups, never took more than 2 hours to go through 4 carbs and reinstall them.

Hi! you may have fuel flooding. You will need to fix the jettings of the carb. It wont be a tough fix, just gonna require a lot of patience. Hope this helps and have a good one!

After start it backfires, sputters then runs


Hi,when starting bike you put the chock on,remeber this is to make a richer mixture for cold start,so when you start the bike put put the choke off a little bit as it warms up,other wise wat you are doing is couseing it to floud,so again as the bike warms up put the choke off little bit at a time,all the best.
