So, I had an issue the other day was messing with my bike out of boredom trying to get this problem fixed that i started the thread about. Checked over carb and put it back on. After that , it was not running good at all. It wouldnt run without choke. So yes, the plugs were black and I changed them and the oil (not fuel smell). Took carb off again thinking maybe a clogged pilot jet. Carb looked ok. There was some build up on the float bowl oring ( after 1 year , thats your ethanol!). Cleaned it up again and put a new gasket on. Put it together and it wasn't running good. So, I checked it over and saw the vacuum hose was not connected to the carb. Oops! Put it back on and the bike is like a new bike. It runs great . However, the original problem is still there. It still cuts out at w.o.t. I did notice it takes longer to do it though and for some reason the bike sounds very different to me. It does start a lot better. I changed the idle and the air/fuel ratio. i think I got it tuned perfectly. No hanging or anything with blip of the throttle. It's just that W.O.T problem. Any more ideas/suggestions on what to check. Ive checked everything mentioned. Vaccuum lines are new. Its only those 3 on the T right? The ones going to the carb and the petcock/tank. Pair mod was done. Petcock was pulled off and cleaned out last year. New filters (air and fuel (petcock screen). Fuel is getting to the carb. Maybe it's the main jet? Should I try a different one. i would hate to change anything since it's running so well. What about the float level measurement (I know its not adjustable) but I may have measured incorrectly. . The carb is getting fuel though. Not the usual symptoms of a bad one , but maybe a TPS? Im assuming Heffly is referring to the 2 screens , the one in the carb and the one in the tank? Im stumped! Thanks for any help!
