80 inch bored .010 over screamin eagle heads,, vance and hines 2 into 1 pro pipe, 10.5-1 hd pistons. all this just done by the dealer at their recommendation. has had an se4 cam for 12 years

 

Well if its run good for 12.years i guess... But its probly a vent that's plugged up or petcock an issue. Id still take the carb off and make sure there's no leaks and check jets and floats. Another guess is the nose cone pickup for the ignition.

 

Ok finally got my bike back and kit seems to run ok.. They pulled the crossover hose to drain the tank so they could pull the petcock and the fuel glugged out instead of flowing. Venting problem. Thanx for all the replies and tips
