    Hi Lonesome Twins,

    during our Summer Party I have started a new project.
    It is a B1, engine was “running” last year, unknown history.
    Needs the typical inspection, cleaning and new parts (tires, battery, fluids, etc.)
    In addition it should be a mild Caferacer, but Clip-Ons are a must !
    I want to keep it as original as possible, but front (lamp, meters, etc.) and recessed footpegs need extra attention.
    A new seat as well and I want to keep it suitable for two persons.

    Downpipes are already individually made from stainless steel and exhausts are Louis universal long. It is very likely that our TÃœV will approve that.
    K+Ns instead of airbox are on the list as well.

    Ok, some pics of this very early stage.

    Cheers, Michael

    Your summer party looked amazing. I am so jealous. I wish my garden was big enough to host one.

    That looks quite a nice project too. It will be interesting to see how you modify it but keep it kind of original.

    I await . . .

    Ok, next idea is to change the rear frame while keeping the stock rear light.
    The upright metal plate that holds the rear light needs to go inwards a few centimeters (approx. 5 cm / 2 inches)
    Needs some cutting and welding 😉
    Will change rear light holder to US-version without flasher holder (already in stock).
    Rear flasher will be mounted at the stock frame position.
    The Clip-Ons change the silhouette significantly !
    Cheers, Michael

    This is how the rear end may look like when changes are done.

    Tinkered a bit this weekend 😉

    Rear light holder plate already cut off.
    Needs some preparation before welding to new position.
    Rear flashers in new old position 😉
    Fitted a pillion grab rail.

    Recessed footpegs and their holders are a challenge. Needs repositioning.
    Will do the rear brake actuation similar to Beachcomber has done it.
    Thank you, Sir, for that example !

    Removed the airbox out of the frame by cutting it into pieces with a grinder.

    With the clip-ons I need to have a different front master brake cylinder.
    Must be much more slim than the stock one.

    Cheers, Michael

    Managed to adopt the cut-off tail end to slide onto the rear frame tubes. Can adjust the depth of the tail light to desired position.

    Already modified rear plastic fairing got a further cut out at the inside to allow the new position of the tail light.
    Got a modern front master brake cylinder (5/8″) with external fluid container.
    It is a large round one, similar to the stock one in 1977. We will see if I keep it.

    Removed the cover and the “mouse-treated” foam rubber padding from the metal seat plate. This allows me to optimise the form/shape of the seat plate.

    Found a nice aluminium chain guard of a Zephyr model. Front mounting hole matches perfectly, for the rear a new holder needs to be made.

    Cheers, Michael

    The natural curves on these bikes lend themselves to many custom modifications with style.

    I had Tango at mine again today while we put his back end on again. It just flows with the curves.

    The way you are doing yours Michael is making the bike look big.

    … is making the bike look big.

    Is that meant to be good or bad ???
    (Sorry, I don’t understand the intention of this sentence)
    😉

    Hi Michael

    It is not a good or bad comment. It is just an observation. With the changes that you have made the bike looks larger. That to me is a nice thing.

    Hi Andy,

    thank you for explaining that to me 😉

    Well, it is a 750 ccm motorbike.
    In the 1970s that was a “Bigbike”.
    That suits me fine 😉

    Looking forward to shape the seat plate to match my “design” concept.
    Then moving forward to get the right upholstery and seat cover done.

    Front end with headlight and it’s holders plus instruments (speed and rev counters) needs more attention, too.

    But this is going to be my winter project and hopefully it is finished next summer.

    Cheers, Michael
