Hawk dlx high RPM
 

Another nut scratcher. Bike had to have ECM changed and the fuel pump wire fixed. Bike has been running better than it ever has until today. Go to come to a stop and noticed coasting down the gears it was a lot slower to do so, coming to second gear it held enough revs to keep going about 15mph without throttle. Shifting to neutral it revved out to around 3.5-4k and could hear little pops out the exhaust. Going to accelerate it kinda bogged down and then ran like normal and would drop rpm enough to shift smooth.

Checked the throttle cable and there's slack at the bottom and the throttle itself is snapping shut no problem. Took the intake boot off and the flapper is closing all the way. Before I freeze my butt off tearing plastics off is there anything you guys can suggest in looking at?

Sounds like a vac leak somewhere to me

Finally have some time to look. Did spray brakeleen iall around air side of things but couldn't get an rpm change. Any place other than throttle body to engine that an air leak could happen ?
