idles fine/ idles high/ idles low ?

[Wewaman]

Hello Ethel it's me again 

I have a question for ALL you VALK HEADS     

My Valk has been running just fine EXCEPT    it will idle at 1000 rpms for weeks.  Then all of a sudden I will come to a stop and it will stumble with the idle at about 600-700 rpm's.  I will adjust it back to 1000 rpms and it will run fine for a couple days.  Then when I got home last night and pulled her into the Biker Barn and put her in neutral she was idleing at about 1200/1300 rpms, readjust back to 1000 RPM's,  rode to work and all is well... ???
       This is a continious cycle of events ,  Will run great for weeks at a time but then,,,

Obvious question Why is she doing that?

Thanks for your input and suggestions

First off insure the throttle cables have plenty of slack.

Second, thoroughly slather a spray lubricant over all the throttle linkages

and lubricate the throttle cables and throttle sleeve.

This will insure there is no mechanical problem causing your dilemma.

Idle variations are often a sign of vacuum leaks...check the vacuum lines...particularly near the manifold ports...for splits/soft spots.

I will check and lube


Daniel,
thanks I will check on that,  I had some loose clamps that needed re-tightening when I did my De- Smog  Will check it all again.
I did the de-smog and replaced with Vac caps.

Check the caps for splits...also could be intake o-rings?

Remove the vac cap fittings. Take one to ACE and get a short bolt with a brass washer. Replace with these. Carry the vac cap fittings in your battery box for future carb balancing.

Or get into your buddy's Gold Wing junk stash. IIRC, the GL1000/1100/1200 intake runner vacuum port block-off screws are of the same diameter and thread pitch as those fittings used on the Valkyrie intake runners.

talked to a co worker he will stop by his parts shed and see if he can get some off of a GW he was given.

Thanks for the input,

YOU ALL ROCK

I also thought fuel carb jet fouling.  How many miles are we taking here?

Run some carb cleaner through when idle drops down. If the bike doesn't stall, then I wouldn't change the idle speed.

My IS used to change speed too, but usually only for a short time. One or two lights.
