    Some more pictures for the followers ..
    The Speedometer sensor is mounted to the stock (rear wheel cable) lug on the swingarm so no ugly cable to the front.. The sensor gets its signal from a magnet in one of the Allen bolts



    All Allen bolts were/will be milled on a lathe to get a conical look..
    Some nice spacers were made for the front wheel as we no longer needed the speedo drive..



    Trial sitting to check on seating position, we ended up with FZR600 clipons (I guess) mounted on top of the triple tree.









    Our first try to finish the electrics was a homemade (cut up stock) wiring harness…



    …but my pal wanted to install a Motogadget M-Unit and that is why everything slowed to a halt… The M-Unit recognises negative pulses from push buttons but I wanted to use the stock switches and was convinced I could get them to work with the M-Unit. I tried everything using relais and so on, called with the fabricator who agreed my thinking was correct but every time we ended up with the brake light glowing very dim after power was switched off. I suspect the connection to earth staying intact after the obligatory pulse messed up the M-Unit . So, after a very long stressfull time I decided to f*ck it and change the switchgear to push buttons …





    Off course cables will be cleaned up later ...
    Some more detail pics …











    Here is the definitive look at the front.. some yellow foil on the inside of the glass …



    Last summer we started the bike for the first time in maybe 15 years and it ran lousy…. until the exhaust spat out two cleaning cloths (one left, one right) which my pal put in before sandblasting … and forgot …. hahaha what a DICK.. Then after half an hour the bike ran nice except fort he right cylinder which could not be synchronised. Turned out one of the stainless bolts from the right intake boot in place was 0.5mm too long leaving a gap between cylinder and intake boot. After correcting that the bike ran like new within minutes…. ! The sound is SWEET! Not loud at all and way nicer than stock..



    The seat bottom was made of a surf board and different types of foam were glued on and cut and cut and glued on again He will not be riding solo as you can see, but I still like the looks. The seat is now with an upholsterer who will finish it in two colors..



    At the moment we are working on a new battery box. After trying several sizes and locations like this one we now decided for a fairly large battery in a hinged box. Trial fitting it to the left of the engine messed up the seating postion so now we are looking to fit the battery under the swingarm, behind the engine.…



    Will be continued …..

        This guy rides an almost 100% stock bike, but, I must say I like how your bike is taking on a unique form and personality. The attention to detail is pretty sweet. Looking great so far.

          That valve cover has unusual knobs on it. Are those supposed to be hand-tightened instead of using the allen bolts?

            Do you mean the engine that is lying in the foreground? That is from a Benelli Sei, the knobs are finned covers for the valve adjusters. Finned for extra cooling, was an accessory in those days (for Honda's).

              OK, I thought you had a tricked-out head or something.

                      Good to hear from you Mathh! Your progress is lookin' good! Some more of those interesting pics that definitely had some forthought is ALWAYS good!
                      One other thought...............think you know, but I'll cut you some slack pertaining to that twin-sparred framed XS11 you were working on getting those outer tube spars correctly/evenly around the xs11's outer two cyl.cooling fins.
                      Anyway, more pics of current project would be most interesting.
