I have TTR250 with a Biggun system on it. I noticed that sometimes it seem to idle high. When I burp the throttle it comes down to the proper rpm. I have tried to adjust the pilot screw and still no change. I pulled out the choke once while it was reving high (hot) and it even revved higher
I'm running a 146 main jet and moved the needle one position richer. The high idle can be felt even while I'm riding sometimes. Any ideas what could be causing it?
