    Stuck fuel cap

    When I bought a 1981 GS650 that the owner had lost the keys, I was able to find a short key for the lock ID number from a retired locksmith. The short key worked in all locks, but not the ignition. Fuel cap, helmet lock, and seat lock all worked with the short key. I had to use the short key to...

    Cleaned Carbs - Can't Set Idle

    Definitely the chock plungers, but good to go now. Synched the carbs, put the tank back on, and out on the road for a 20 mile loop. Running well. Thanks for the suggestions. Dave

    Cleaned Carbs - Can't Set Idle

    I have fiddles with it. A little bit of slack is present. It may have been not tracking well in the grove where the cable is anchored. Re-positioned so that it tracks better and will see how it goes today.

    Cleaned Carbs - Can't Set Idle

    I think I have things straightened out, but not sure if I can do anything to make sure the problem doesn't persist. Removed the choke and throttle brackets from the carbs again and the engine was running perfectly. Idling at 1,400 RPM and would react appropriately to throttle input. Went ahead...

    Cleaned Carbs - Can't Set Idle

    Intake boots and o-rings are in good shape. No rubber bits were dipped including the choke plungers. Airbox side looks ok, but I will need to get some spray and see if I can sens any further idle change due to a vacuum leak. Nothing is sealing the airbox other than the two slide on clips that...

    Cleaned Carbs - Can't Set Idle

    1 gallon pail of Berryman's Chem-Dip. The pail is probably 7 years old. Don't think it would possible to make the choke work in the opposite direction. Slides out with the pull on the choke cable. All jets are original. Did replace the needle valves and valve seats this time with OEM parts.

    Cleaned Carbs - Can't Set Idle

    Choke was fully open to start, but could close it pretty quickly without affecting idle.

    Cleaned Carbs - Can't Set Idle

    Maybe another symptom to think about. No adjustments made, started the bike again today. Fired up on the first crank and was running around 1,200 RPM. As the engine warms the idle increases. Maybe expect that a bit, but it just keeps going. Was up closer to 2,000 RPM after running for 5 minutes...

    Well that sucks. They looked ok to me, but that doesn't mean much...

    Cleaned Carbs - Can't Set Idle

    I did bench sync before installing and then connected the carbtune which showed pretty good balance. During the carbtune and balancing I had removed the throttle cable bracket from the carburetor since it was in the way, but no effect on the idle. Dave

    Cleaned Carbs - Can't Set Idle

    1981 GS650L Over the winter I broke down the carbs, dipped each for a week, and then put back together to be ready for spring. Carbs back on the bike today and running ok, but I can't reduce the idle. It is running at 2,500-3,000 RPM no matter what I do with the idle adjuster screw. Nearly...

    Number 2 Cylinder Still Running Cold

    Steve and FastBySuzuki, I did replace the petcock with OEM early on. The original was probably fine too, but I didn't notice until swapping in the new one that the PO had used star washers and no gaskets to make the connection to the tank which was the cause of the leaks The tank has been off...

    Number 2 Cylinder Still Running Cold

    Good idea, but cold cylinder stayed at No. 2.

    Number 2 Cylinder Still Running Cold

    Still struggling to get my 1981 GS650 running well again and I am pretty much at a loss for next steps now. The engine has experienced a full re-build and is running again, but the number 2 cylinder is running much colder than the other 3 cylinders. It is also running a bit erratically now and...
