Idle steady at 1700 rpm....

[Guest]

Hello
My Gs1100E -82 have problems to run idle below 17 rpm.
This may be OK as a result of mild tuned engine.. ? The top are ported and Hot Street cams + 4-1 pipes + pods.
Origin carbs with Stage-3 kit .

It runs and start very good, but start hesitating and unstable under 1700 rpm.

Any with similar experience ?

I would balance the carbs first and then check the mixture with a Gunson colortune spark plug.

Well 17 RPM is super low.... lol

Now 1700 RPM is a little high.

Id check for leaks around the boots. After that, try turning the idle mixture screws in about 1/4 turn and see if it gets better or worse (after its warmed up). If it gets worse then turn them out 1/2 turn. See if it gets better or worse and you'll know which direction to go.
