Idle

Postby Keef » Mon Mar 02, 2015 8:20 am



I would like to know what would cause your Idle to go up and down. Mine does it ONLY in the winter when it is say around
35 or below. It runs between 900rpm-1300rpm. Back n forth, back n forth. Warmer temps it does just fine. It is aggravating
because when you go to shift it might be going up. Any ideals any one,,,,,,,,,,,,,thanks Keith

I suspect a carb/vacuum issue because your idle is a little too high to start with and gets set there to cover other problems. Base idle is supposed to be 800RPM +/- a bit. Turn it down to the 750-800RPM area, it should run good and stable there and might eliminate the surging.

With bike at operating temp and on center stand slowly turn down idle until it stalls and note the RPM.
This is what I do
Local and need repair help with your 1500, Valkyrie or ST please PM

My 88 did that when the idle was set too high. Set it back down to 800 and it was fine.

Have a '97 that did that when I first got it. Ran 1/2 can of Seafoam through a tank of gas, with particular attention to allowing it to idle a lot to clean out the idle parts. Fixed it in one tank. I have been running Seafoam 3-4 oz. in every tank of gas since, for maintenance. Also got in the habit of mixing TCW-3 2-stroke oil in each tank, 2 oz., on the advice of several folks on the forums. It seems to run a little better with some oil, and the mixture is so weak that it doesn't effect the burn or the plugs.

I run 1/2 a can of Seafoam to a full tank of gas about twice per year. That keeps the fuel system clean. I am not familiar with the running two stroke oil in the gas of a 4 stroke engine.
