    So, been hankering after a "proper" trick framed bike for some time now...... And as a dedicated Kawasaki fan - Big Zeds, when this bike turned up I just had to go for it...... :evil

    In the latest issue of Practical Sportbikes they make a mention of the Harris frames and quoted them as "sited in many divorce petitions." :rofl

    That looks really light and zippy. I'm not a huge fan of inline 4s in general, but that thing looks like stupid amounts of fun.

    Nice frame and components, now ditch the John Deere paint and the IL4, find a H2 motor and Bobs you uncle. :evil

    Right then chaps - as you know the Harris is all about HANDLING - so I shall not be tweaking the motor too much, I've a set of slightly "lumpier" cams and some VM29 smoothbore Mikuni's :evil

    Here's a period write up for the Magnum 2, from Nov 1982.....

    So far I've sold the GSXR USD front end and the Ducati 916 rear end - as they are the usual suspects for modded bikes :huh My plan is to keep it looking a bit more Old Skool.

    I have a ZZR1100 RWU front end and have tracked down a loverly JMC, double braced swing arm, and some 17" DYMAGS :clap

    Let the DIVORCE PROCEEDING's begin
    :huh

    One of the standard discs has a bent rotor, so I have got a nice new front set, to compliment the rear disc...

    [​IMG]

    The JMC will need about 10mm removed from the frame pivot point - which will also mean the needle rollers have to be recessed accordingly. I have pressed the stem out of the ZZR tripple trees and will get a new one made up to fit on the Harris headstock.

    Got a bit of frame brazing to sort out too - the lower rear engine mounts have been removed - but they came with the "box of bits" so just need cleaning up & sticking back on :lol3

    Good call! I hate the single sided swingarm conversions. That JMC arm with those Dymags will look freaking sweet.:beer

    Well done, laddo. :thumb

    Would a J motor suit that chassis? :scratch
    Period correct and a better donk, no?
    :dunno


    I'll be watching this one with interest.

    The later "J" is a bit "fruitier", but I prefer the older (more original) kickstart motors & round cam covers :D

    The engine mountings are different too - and this frame is made for the older model. Once I fit the lumpier cams & VM29's she'll go fast enuff for me........ If I do need a bit more squirt I'll take the motor out of my Sprint bike.... :evil

    I've now had the lugs brazed back on and took the frame and swingarm to TALON for an estimate to trim 7mm off each side of the JMC & make a spindle sleeve - as the Harris spindle is 20mm & the needle bearings are 25mm :shock: They said it would be about a days work (setting up the machines takes a while) and £250 max. I could get it done a bit cheaper, but I want this work done right!!!

    [​IMG]

    In the mean time I've made some card board templates of the lower rear engine mounts, to line up with the lugs..... I had some 10mm ally plate which I'll cut out for the brackets.

    [​IMG]

    I also took Mr JigSaw to the Zed Butt unit & hacked a bit of fiberglass off....

    [​IMG]

    [​IMG]

    The JMC is sitting ON the pivot in those shots and the rear end is sitting rather low.

    I'll make some brackets and make surethe seat is nice and firm to support the rider :??

    I dropped a few bits off to Mikey on Thursday afternoon and took the cam cover off - so I could get my first glimpse of the motor internals....

    [​IMG]

    ..... as luck would have it, the top end looks good, the cams are mint and the clearances are spot on :twisted: As you can also see, the cam caps have the standard bolts fitted - so hopefully no surprises there!

    I think I'll be doing the minimal mechanical work and just give it a thorough service, a bit of a clean up and run it

    That sure is nice, indeedy-do :evil

    I will need to get a lug welded onto each of the ZZR fork legs to fit the Harrison calipers - I don't know what they were made for, but at least the lower lug is in the right place.

    In my stash of parts I have a rear caliper off a Kawasaki ER6N - commuter bike which I'll adapt to fit. I have to wait for a call from Mike at TALON Engineering
    ( http://www.talon-eng.co.uk/ ) and drop the JMC s/arm off for him to machine and make a sleeve to match the spindle & bearings (20mm & 25mm respectively). I could get the work done for about half the price, but I want this bike to be "spot-on" so an estimate of £250 for a days work is what it'll be :eek1 Most of the time is setting up the machinery. Luckily a mate is making the new stem for the yokes (triple trees) :clap

    I managed to strip the Harrison calipers down and give them a thorough seeing to with brake cleaner, at least that didn't cost me anything!!!!
