what's up guys? i've got an '05 S model with just under 1,000 mi. my throttle is sticking open....it seemed to happen all of a sudden. it got harder to twist, and now when i twist the throttle it just stays open to however far i turned it and won't return. any ideas on what the problem is? some quick help would be greatly appreciated because its getting nice here and i'm itching to ride. thanks!
