What up my brothers my bike runs AWESOME thanks for helping me get here. Just giving some props to yall 1ST off! Now she has been jetted thanks Wilson, APE cct, and Yoshi pipe, while riding when temp hits 185+ idle raises and hangs at 3k everytime so I will reach inbetween the left fairing and turn it down and she will idle correctly. But once riding and she cools the idle is too low now, so I am constantly adjusting this thing on a good cruise. Call me CRAZY but I am clueless? what yall think?:dunno

If your idle is hanging up your pilot circuit could be a bit lean. When your idle was high like that, did you blip the throttle at all to settle it down? After your bike is good and warm and it's idling (at it's regular idle) blip the throttle. Does it rise right up immediately and then fall right back down to idle, do the rpms hang up for a minute on the way back to idle, or does it drop/cut-out for a second then rev? Is it the same when the bike is cold as when it is hot?

You could go a half turn out on your pilot screw to richen it up a bit. How many turns are you at again right now?

You should never have to adjust your curb idle while riding. If you do, there is another problem that has to be fixed.

^^^ That, and was a carb sync completed after the jetting?

Thanks for the reply fellas yeah Wilson sometimes I can blip the throttle and it will go back down but most of the time it just slowly raise back up to that 3k mark again. When its up to temp and I blip the throttle it will raise immediately but comes down slow. It only does it when the engine is hot, no problem when its cold. Factory Pro told me to set the screws at 2.5 on all four carbs which I did. I tried the carb cleaner, spray it while its running around the carb boots and airbox fittings and no idle jump. Did a search on this last nite and saw that Black_Rain recommended that so I tried it.
Black_Rain I checked out your videos and you have put in some good riding man and you got SKILLS too. I synched my carbs and FULLY cleaned them twice to make sure they were supa clean, that was about 50 miles before I jetted it. Think I should richen up that pilot circuit??

Yes, turn out the pilot half a turn at a time till it gets better. Should be better within about a turn or two

agreed.

had to do that after my dynojet kit stage 1 was installed on my 99 600. I used to just be sitting at a stop light or something and the bike would rev up on it's own to about 3k.

Thanks for the help man I feel special I got the pros comin on my thread droppin jewels of advice!! I will do as told and post up my results!!! THANKS AGAIN!!! Oh yeah yall come to Nashville anytime TITS and BEER on ME!!! Thats for all people on SRADS!:cheers

You guys have some nice roads too!

Man you aint kiddin the roads are VERY nice and well kept. I am from St.Louis been here 12 years and St.lou roads are horrible to say the least. Ok couldnt do the job correctly because the garage is connected to the house and before starting it I turned the A/F screws out to 3 turns, from 2.5. when I started it on choke it was RICH as hell my eyes started burnin and it was lightly spittin gas out the pipe so I shut the bitch down, my ole lady starts fussin about the smell of gas through the house. But the engine was cold and on choke at 3turns out and it was SUPER RICH, so I turned her back to 2.5 and that richness went away, I am coughin now like i smoked a gas cig, half a turn made a MAJOR difference so I really dont know now!!

how do ur diaphrams look...those rubber boots? perhaps a float is sticking at high temps? also...what rung are those lil clips set at on ur jet needles? i believe mine were on the first rung and my screws were turned out 2 turns....it was long ago, but I think that's what it was.

edit: just read u had the choke on....don't do that. choke on = more fuel....add that with the added turns on the screw = a lot of unburnt gas spittin outta ur pipe. You can stand there and hold the choke lever slightly to keep enough fuel flowing so she won't die on a cold engine....just have to listen to her. Start it with the choke on fully...then ease it off slightly and slowly.

I'm FI, but have the cold start lever, and I usually keep it at half choke in the Winter. Works fine.

Also - this may be hard to do since you have also been playing with ur idle screw inside the fairing. I'd start fresh and get my idle right using that screw and then begin to mess with the screws in the carbs.

Yeh Lean wit it you are right get the screw straight in fairing first then go with the carb screws next so you think I might need to go back to the 3 turns out when the bike is hot and see how she do then??

yea. let her warm up as normal using the choke. then turn the choke off and adjust ur idle using the screw in the fairing to around 1100-1200 rpms. then adjust ur carb screws as noted above and do the sync again if necessary as noted above and see how she does

also, try spraying the carb cleaner directly into the throttle bodies (doesn't take a lot, you don't want to bog her down, just a light misting over each one). Find the spot when it hangs at 3k rpms, then spray in some carb cleaner and see what happens.

Yea I heard carb sync earlier in this post didnt read rest but if the throttle sticks then slowy dies down that what you need

My bad this was already decided as the problem sorry i been up all night

I just did a carb synch about 60 miles ago before the jet kit. yall think I may need to do it again???

Each time the carbs are removed it is a good idea to re-sync the carbs. Doesn't take long to it, and I have seen this myself, sync cured the hangup.

update? how's the bike run now? did you ever find a definate solution? i just got my bike running and am having the same issue lol. i'll try turning the pilot's out a half turn tho...

Same problem with mine, though it's a FI 99 750. My idle screw is extremely sensitive though.. When i turn my idle down it goes from 3k to stalled...

Sync your TBs and make sure that the TPS is adjusted correctly.
