    Default BMW kneeler

    Seeing as it is quiet at the moment Ill throw this to the lions.

    I picked up a new project a couple of months ago to use on my anual Moidart/ Kinlochleven run,its a BMW R75 kneeler. This was being built by a guy to race but fell ill and it lay for some 10yrs then a friend of his put it up for sale. Having discusions with the MOT chappie on what is required to make this road legal then a trip to VOSA to have it sorted out. On closer inspection there are not two wheels in the correct position so I'lll have to clear the jig and rectify.
    First is to remove the scooter chair wheel, I have purchased a 10" minilight along with a road legal Avon advan tyre. New hub aquired and my ex passenger is machining a new spindle as I type.
    Motor has been stripped and measured bead blasted and thoroughly cleaned ready for assembly.
    The motor consists of balanced crank, high comp Omega pistons not knowing the history of the con rods they were sent off to a metal improving company and have just arrived back from being shot peened to relieve stress which also increases the strength by aprox 30%.
    The cylinder heads have been machined to create what is called a splayed head giving a more direct flow of fuel into the cylinders fed by a race cam, Kibblewhite valves and Dellorto carbs, the head has also been twin plugged. Stroll on April.

    That will be good fun but do you not think that a kneeler on the road could be a bit dangerous? It will be so low vehicles in front won't know it's there. You could always fit a flag to it

    It will be bright and LOUD , a friend had mentioned a flag but I could see that taking out pedestrians when cornering. I shall also have daytime led running lights.

    I achieved a little bit of kitchen engineering yesterday. I needed to up the main spine for the chair hub from 1 1/4 to 2" so machined a plug to fit the inside dia of the tube bored the centre then used a 2" hole saw boring each intersection then removing the tube to the next one. Life can be much simpler when the science has been removed, all done within the hour.
