Hi all,
Since I've gotten this bike, if i don't change gear closer to 6k (no lower) it seems like the engine begins to run rich. I can smell gas from the exhaust and there's been afterfire once in a while. Most of time, once she begins running rich, within a few minutes, i'll lose all power and I end up having to pulling over. She'll start right back up (1st kick), but will run rich, and typically lose power again if i don't let her sit for a while.
Everytime I'm on the bike, after riding north of 45mph, I notice that she'll idle around 2-2.5k (at start up and before entering a longer straight away she idles around 1.2-1.5k)
I was told not to shift too low (3k - 4k) and start shifting it higher. My mechanic that told me that also did a full cleaning of the carbs, and full check up (plugs and all). The problem got better, but still persisted (especially on hills where I had to keep her higher than 6.5k)
Recently the problem got really bad, within a 20min ride, the engine just quit (going around 45mph) all of a sudden. I haven't noticed any patterns. It also shuts off when I downshift to a redlight and pull in the clutch. The moment the clutch is pulled in, it completely dies. But it'll start right back up no problem (only kick, no electric start).
Anyone have any idea what's going on here? Not sure if the initial problem is the same problem as what's been happening recently, since it never died when i pulled the clutch in at a stop before.
Clutch? Battery? Plugs? Timing?
