    OK Great, thanks for the clue...I sorta knew it was there, but I'm crawling at this point. I'll get better. Bike is in great shape mechanically, just needs a good going over, cleaning & a little new paint maybe...

    Not quite part of this thread, but it is sortof.
    What size front disc is on the GSPDs that have the caliper upgrade?
    My 1991 has a 285mm( 11" ) Looking at an article on what I believe to be 1992 or 3 model, looks like it is bigger?? I know it appears to be a floating disc.
    Is mine the wrong size for the caliper upgrade?

    All you experts, please help.:cry

    Iknow I should start my own thread, but this one has run off the rails, so I thought it wouldnt matter.:lol3

    I checked the Max site, and yes they are a different p/n. This could be because of one fixed, and the other a floater.
    Can someone "please" measure there later disc for size? Pretty please??:D

    Nothing like a little optimism? :D

    The electric start was an optional extra on the 80/81 bikes so I suppose 370lbs with this junked and a dry bike might be plausible.

    I think it's great the speed you're moving on that bike Solo. If it turns out anything like your Paralever GS it's going to be a great bike.

    One of the UKGsers put his siebenrocked 1000 G/s on the Dyno and It measured 43BHP at the back wheel. The standard bikes obviously going to be a lot lower than that. I've heard 37BHP quoted.

    This is it on the Dyno

    It was built by a Belgian guy and then bought into England by Johnny Boxer, he then sold it onto Wreford Miles (another UKGSer).

    Johnny posted a few of the build pictures here :- http://www.ukgser.com/forums/showpost.php?p=721309&postcount=10

    The frames been heavily reinforced round the cylinder head and swinging arm pivots along with a 4" extension on the swinging arm. It's a really nice bike when you see it.

    The European guys spend a fortune on their Airheads and never seem to hesitate to hack them about to suit their needs..quite an eye opener.

    Weissbeers (Danish GSer) mono is one of my favourites - http://www.ukgser.com/forums/showpost.php?p=1113501&postcount=54

    I enjoyed the video of the Dyno test, but correct me if I am mistaken: did that old airhead take a dump at :19 and :40.

    Sure looks like it. Check out the center of the engine under acceleration.

    :wink:
