    Thanks KK!

    I haven’t fix the starter clutch yet and I am not sure what has gone wrong with petcock valve, it worked fine before the “restoration”. At the moment, the fuel is not passing through when the valve is at “ON”, so when the engine is running, I have to put the valve at “PRI”. Is it possible that we connected the pipes wrongly or something?

    Cheers, Marko

    The petcock is vacuum operated. When the tap is set to ON or RES and the engine is running a vacuum is created by the carbs via pipes from the petcock which opens a diaphragm and lets the fuel flow. When the petcock is in PRI position this bypasses the need for the vacuum.

    It is my thoughts the vacuum pipes have not been correctly installed. There appears to be 2 different ways of these being fitted. On the CSR model each carb is connected to 2 legs of a ‘T’ fitting. The 3rd leg is then connected to the petcock. The Y LTD model is connevted differently which Michael described in another thread recently. I will try to find a link. I am not sure which way the S LTD model should be but probably either would work.

    Cheers

    I will check the connections over the weekend, maybe I will find the solution. I suppose there is also a possibility that the petcock is not functioning properly anymore.

    Cheers, Marko

    Hello everybody,

    I just wanted to say hi after a long time! I hope you are all well and healthy.

    My Twin is still running well, just needs some attention from time to time. In the meanwhile, I bought another Twin – well kind of, it is BMW F800R. I use it mostly for daily commute to work , not a bad bike to be honest.

    Cheers and stay healthy!

    Hi Marko

    I can only really speak for myself but I am well thank you and hope you are too.

    Not too much has changed since your last visit but I have added a shop which I am trying to expand daily.

    It’s good to hear she’s still running well and to see you are preserving your twin.

    Cheers
