i still have the feeling like i am running out of gas.
when trying to maintain a steady speed i get kind of a hesitation and a surging. sometimes i even get a back fire on acceleration.
Motorat-
This is sounding rather like my problem, and I looked through this thread and didn't find mentions, so...
Sorry if it's obvious - my bike behaved like it was running out of gas, basically like you described (no backfires, but what the heck) - turns out it was a broken negative battery cable terminal end. The shrink-wrap was holding it together, sort of - just enough to make it look ok, and just enough to maintain continuity,
most of the time. In the end, it stopped altogether but I knew right where to look, thanks to this forum. Might be worth a check if you haven't already...
