stuck idler knob
« on: March 17, 2019, 03:02:19 pm »
Hello all, haven't posted in awhile. Just took my bike out of winter hibernation. (I normally keep it under a tarp on my lawn during the winter months). noticed that it is only idling at 1000 rpm's. when I attempted to adjust the idle, the knob won't budge. try turning it both ways was afraid of breaking it, so now I'm posting to get some help. Thanks

tough spot to get at, and see with tank on..
 but in the middle of the carb "bank" the adjuster screws into/thru a "boss", and has a spring on it ...needs a little "sprits" of lube there.. and should work/turn then...

well had the tank off a few days ago, and spritz the hell out of all the stuff that had anything that I could see that had a spring, cable, or lever, or anything else that I thought needing spritzing. the idler knob is still stuck. took the bike to work last night and the bike died on me a few times, both while moving and coming to a stop. couldn't maintain the rpm's. the rpm's would drop to zero whenever I pulled the clutch in. me thinks there might be something else going on. will have to yank the carbs and spark plugs off and taker a close look. I did have a leaking petcock this winter. might have to invest in a more modern steed if my findings are dire.

what is your idle at neutral? does it idle at 1000-1200?

what year and how many miles? maybe time for a carb overhaul. if that's the issue may still be cheaper than buying a new bike.

it fluctuates at 1000 and a little below. it's an 05 and has 110,000+. Drained the tank earlier. Thanks

you should be able to run fine at those idle rpms. the manuf calls for approx 1000rpm. No more. so your idle rpm is fine and should be left at that.

You likely have a carb issue. time for a carb teardown. has anyone done any carb cleaning in 110K miles? if not it is high time. you may have a blocked passage from winter storage. did you treat fuel before storage?

I usually put fuel stabilizer in the tank before I stop riding it. haven't done any tear down. But I might have to because the Idler knob won't turn. just gotta wait for the weather to clear.

I wonder if you have stopped up pilot jets/passages and the idle adjustment was screwed in all the way and stuck.
I think I recall that the ideal idle is 1050-1100.

Ride safe, Ted

I remember last riding season, had to adjust the idler screw, there was plenty of free play both ways. Just when I took the bike out this season, was the idler screw stuck.

Ok, must be corrosion on the threads then.
You'll get it soon.

Ride safe, Ted
