While under a load my bike seems to idle a little bit rough. Also while riding there are moments where I get like a surge of power like in suddenly has all the power in the world. And then it goes away. Not quite sure what to check to correct this issue is it vacuum, spark or fuel? Maybe I need to adjust the pms screws? It does have the modified stock exhaust. Could that be a back pressure problem. Kinda at a loss here. I am a pretty good mechanic. I work on BlackHawks and I know my way around a vehicle’s engine. Not too terribly experienced with bikes. I see a lot of people talking about ais delete and other mods like big air and pod kits. I honestly just want this thing running. all next week it’s gonna be in the 70s here and I would love to ride!!
