I noticed you are running a 140 main jet. What size was the stock jet? Also does your fuel have ethanol in it? Our fuel I think is 10% ethanol. I have a 125 main in the blue buggy and it is pretty close, might go up to a 127.5 that I have. My 155cc red buggy with a 122 main and 34 pilot runs fast and climbs well.
