Re: what did you do to your motor bike today? Rode mine to the end of the block today. Out of 6 attempts, I made it all the way twice. The problem of the wide-open throttle only came back once, when I didn't have the cap thingy screwed in all the way & the brass barrel slipped out of position. Just b-a-r-e-l-y missed nailing the van parked across the street. (That was pretty fun, I gotta admit). Still working on the throttle adjustment. It kinda works a little, but it doesn't make much of a difference if it's mostly pulled or mostly relaxed, the result is about the same: it just kinda runs. RC - good call. Turns out the barrel was the problem. I got it sliding, but I think it's in backwards....the groove is on the clutch side & the bottom notch is on the drive side. Is that probably why the throttle isn't doing as much as it could?
