By building up idle fast I mean a FAST idle. As in 1/2 throttle open kind of rpm's... I did find that my slide wasn't closing all the way, so I adjusted the cable so that it would. It seemed to be running better as I rode it around the block a few times, but then the throttle stuck (grip twisted back, but the rpms stayed up there) and I had to shut it down again...
I think I am going to just take it to the dealer and let them sort it out... I hate spending the $$, but also don't want the throttle to stick and send me into a tree...
I race hare scrambles, and although there is a fair amount of tight stuff, there is also plenty of WTFO throttle on our courses. The plug has never fouled out during a race, but the bike just won't start the next time I use it until I put a new plug in. When I pull it out, it is black...
