since i haven't really had a chance to ride it, i don't know what is NORMAL for these bikes. I had thought about replacing the seat but i'm now thinking a custom made seat may be in order. I'm a little thick and the wide front part of the seat causes my left leg to gramp almost imediatley.
I don't know how he cleaned the carbs or what he done with them but i'm running seafoam in my gas. 100 miles so far. Still a smooth ride.
