COuple of weeks ago tryed to jet and put HMf pipe on. Now the Bike wont start at all, and all it does is make a electric starter sound and blowing air out of the exhaust. I tried to empty the gas out of the carb, empty the gas tank, check, the values, Tired to pull it behind another atv and it wouldnt start. But it would try to turn over when I pull the clutch in it would lock the back tires. The Jetting was stock 120 jet and i got from the pipe 135 jet. I am at An elevation of 3500 feet. Need help !!!!!!!!!!!! I think it is the Jet but not sure.

 

Well do you have everything connected tightly like the boot that goes on the filter and carb...also are you getting any gas to the engine because if you aren't careful when rejetting you may mess up the float of the carb and cause it to not get gas...check to see if gas is getting to the carb and also make sure the pcv part isn't crimped in the airbox and is able to breath...is it just a slip on or a full system?

 

The pipe is a FUll exhuast pipe?

 

Alright I was just wondering because it will depend on how high of a main jet you go and have you changed the pilot jet...The main jet will only kick in at higher rpms so if that is the only jet you messed with then I prob wouldn't say it is your jetting, but if you aren't getting gas or maybe your airfilter is iced up or something blocking the air then I would say that is the prob...one last thing are you sure you have all the connections to the carb at the correct spots
