Having issues....

[pjm204]

I installed a full supertrapp exhaust on my GS yesterday, it was idling a little low so I attempted to tune it with the finger screw on the bottom. Turning it in either direction did not cause the RPM's to change. It seems to idle at round 1400 or so now which I think is okay but it returns very slowly from like 5-6k to idle. Any idea what is up. It is a 2001 with stock jetting, 6 discs in exhaust which the manual to the exhaust says is good for stock jetting. HELP!! thanks
