I put the HMF utility pipe on about 3 months ago and added a KN filter and replaced the stock jet with the jet that came with the pipe and it ran like a champ until last night. It acted light it was flooded and did not want to start or idle. After a few minutes of checking the gas, choking it, setting the fule on reserve it cranked and ran awesome. I thought it might have some trash in the carb, no big deal. Tonight I crank it up and ride it for a little while and come back home a shut it off and go back to ride it again after 2-3 hours the same issues are back just like last night. The only thing I have not checked is the plug. Does anyone know where the problem might be?
