Title: RPMs hang
Post by: albertinhouston on October 23, 2010, 01:51:46 PM
I was reading before about hanging RPM. couldn't find it again.  I have checked my carbs for vac. leak but all seems good.  96 model
any suggestions?

Turn down your idle. I know it might seem like it's ok, but let the bike warm up and just keep adjusting it down until it stops doing it. It's a pretty common problem.

My bad tt,
  The RPM's will eventually drop after several seconds. It's after I give it gas or i'm shifting down to 1st at a stop. 
It's not the idle screw setting. I've gone through that already. I might pull the carbs again and double check them again I guess. :(

That's exactly how mine does if i go a half a turn too far on the idle.  try turning it down a half turn before you tear into your carbs?  also, try lube on the throttle linkages, etc.

Yeah if you say you already went through the idle screw thing and that's not the issue, I'll believe you, but the things you just mentioned are definitely the side affects of your idle being too high. You start the bike, and it seems to idle well, but after you give it gas it doesn't want to go down. It either hangs and then drops, just drops extremely slow, or sometimes will just stay high and you have to slip the clutch slightly to get it back down. If you can't turn your idle down any further you'll have to look into you carbs. I just encourage a double check because I spent a whole week dealing with that, checking for air leaks and everything else under the sun, and even though I had heard about the idle being adjusted too high, I didn't think that was it, but eventually I figured out it was.

Now that I thought about it, when I first got the bike I put a screw on adjustment screw (from the top) and changed it abit. Now thinking about it it was the butterfly addjustment screws. maybe I unsync'd my carbs.

I haven't messed with the bike since hte weekend but I think that might be my culprit.
