Wee throttle surging, rust in gas tank?
I bought a barely used 2006 Wee recently (only 400 miles on it) and found it had rust in the tank. I've been riding it quite a bit recently, and it started exhibiting some very strange symptoms.
After riding for a while, the bike will start to "surge". I will have the throttle rolled on, but it will act like I just rolled off and the RPMs will dip drastically and the throttle simply won't do anything. Then all of a sudden the bike will surge ahead like I just gave it a huge rev. Once this starts, the surging continues until I basically put the bike away for the day and come back another day.
From doing various forum searches, it seems like it could be a throttle body issue, but with the rust in the tank, I am wondering if it is merely a fuel system issue and I need to clean out all the rust, check the filter, etc.
Appreciate any help!
