Rexxis
Almost there...
The bike starts on 2 or 3 kicks when it's cold and on 1st kick once it's warmed up.
It idles very well from a cold start, nice and lopey. after abt 5 minutes or so, just enough time to warm up, she begins to idle higher. Not anything crazy high, maybe like the throttle is just barely open. First thing I am thinking is air leak but I've sprayed cleaner all around the gaskets, boots(JBM), and throttle shafts(yes, I have replaced throttle shaft seals with OEM yamaha seals). All of these have no effect, so it would seem there is no air leak. At least not one that I can find. The carbs have been gone through, cleaned, and rebuilt. I even replaced needle jet o-rings.
The bike is running really rich on the left side and really lean on the right when reading the plugs. Seems like I might be over-jetted and have an air leak on the right(lean) side. On a side note, I used the dead cylinder method to set my air screws. I did this when the bike was cold. I also synced my carbs two nights ago. the bike was warmed up by the time we finished and it was doing the high idle thing. Question. Once the carbs were synced, if I adjusted the idle screw, it would throw the sync off. It would seem to me that the idle adjust should have no effect on the syncing of the carbs, correct?
When riding, the bike wants to stumble a little bit when cruising with the throttle just cracked open. Once I give more throttle, this disappears and the bike runs strong all the way to WOT. I haven't done this much since the right side seems to be running lean. No holed pistons please.
I've got 20 days to get her running right, I'm scheduled for Just Kickers in Davis, Ok on the 26th. http://justkickers.blogspot.com/
