    Slow progress at the moment........ Now the 5/8" off-set drive sprox are done & collected from Talon......

    [​IMG]

    Whilst there I asked them to make me up a special sprocket adaptor coz I need a total of 28mm off-set for the 190 section tyre fitted on the Dymag.

    [​IMG]

    I need to set the rear wheel sprox in by 12mm, so they will make a plate to fit where the sprox should live and then I can fit an "off-the-shelf" item to the inboard side of that - and voila, sorted !!!!!!

    Once thats done I'll get some 530 H/D chain and the drive line will be complete :evil: All in the c&s effort will be just over £200 :huh


    I've contacted a chap who powder coated my Mk.II Sprinter and he can do me frame, yokes, s/stand & mounting piece for about £150, so should get that down to him next week - 7 - 10 day turn-around :D

    Quick question Pigford, if you offset a sprocket like that (ie move it out) doesn't it put an eccentric load on the output shaft and bearing?

    YES - but depends on what motor you're running........... My (K)Z1000A2 is only 1075 Wiseco, making 90 bhp at the wheel amd I've run loads of 1/4 miles & about 10k miles with no problems :D

    [​IMG]

    My Mk.II Sprinter on the other hand is 1392 & I'm running with a D&G outrigger :evil

    But the motor is only gonna be 1105 Wiseco, but I think I'm gonna make my own outrigger plate for this bike :clap

    Got the sprocket adaptor from TALON this afternoon..... to be polished within an inch of its life :evil

    So thats brung it in 12mm - and the drive sprox is out by 5/8" - Jobs a goodun :clap

    The adaptor allows fitting of a standard "off-the-shelf" sprox - in this case one for a VRF800

    I finally got round to drilling out the broken/rusted bolt remains & re-tapping - this is to hold the side stand kaboodal :D


    [​IMG]

    Next is fitting the brakes.... I've gone thru' a few options, this being one that I've now rejected.....

    [​IMG]

    It's a proper MICRON adaptor - converts the forks to use common Nissin 4-pots, etc.

    I'm gonna use the lower caliper mount as a direct fit - just need 5mm shaved off the inside to align it - then make a small adaptor lug out of 10mm alloy plate, then JOB DONE :clap I had wanted to get a new lug welded on, but the chap reckons alloy fork sliders will most likely deform/shrink if welded and the fork action may suffer

    That stuff is more common in Europe because people build sportbikes a lot. Over here most people build choppers and bobbers and other such BS...

    Nearly - but not quite :huh They match better in "real life" - me camera phone is a bit naff :lol3

    Must admit, there's plenty of quality "bolt-ons" to be had over here - but you American lads have access to the top notch engine kit :evil

    Has been a bit quiet recently - but finally got the front end sorted, Harris clip-on's & brakes all plumbed in, etc......

    I've also mounted the fiberglass electrics tray & covered it in hi-tech heat reflective tin stuff....

    [​IMG]

    Next on the list was the rear shock.....

    [​IMG]

    ... turns out its an old SHOWA unit - so I sent it off to an old boy who has a few years of experience and he's re-furbished it with a new rod & seals, plus fresh oil, reduced the rebound damping and re-charged with nitrogen (or summink like that). Have to sort the mount to the swingarm now :huh

    At last - the Rolling Chassis is completed (more or less) :clap

    The chaps at Faulkner Springs measured the rate of the one me SHOWA had fitted and sure enuff it was a 450lb effort - what normally gets fitted to a Harris Mag 1 :evil I contacted Harris for a bit of advice - and Lester himself called me back for a chat :victory: 450lb is right for a 2:1 leverage ratio, but with the JMC its just over 3:1, so I ordered a 650 lb spring to try...... Anyhow after weeks & weeks of trying to suss out sorting the shock mounting to the JMC - I finally decided to uses some M20 studding, knocked up summink to fit the shock and made an alloy block to fit to the top brace.....

    [​IMG]

    [​IMG]

    [​IMG]

    A local bike Engineer cut & welded it for me.... This friggin' JMC has cost me an arm & a leg :doh:

    SO, fitted it all together and it's looking OK....

    [​IMG]

    You can see the typical adjustment range as it is at the mo' - but I can lower it another 50mm by taking off the backing nut if needed .....

    LOWEST:

    [​IMG]

    HIGHEST:

    [​IMG]

    Also got hold of a proper Harris seat unit......... just gotta decide if I'm gonna use it :shrug

    [​IMG]

    Finally checked on GROUND CLEARANCE for hacking down to the chippy on a Summers evening :freaky
