    Wasn't exactly straight forward repower & the xj550 wheel was awkward. 50kg lighter than a std H2 & double the power the 350lc etc.
    It is a remarkably straightforward operation to adapt the Kaw mill to Yam chassis, & the XJ wheel mod is likewise not moon rocket stuff..

    The extra power from more than doubling the capacity is expected, but the improved steering/handling/roadholding is a bonus..

    The larger Kaw mill means the 'flighty' light feel at the front end of the RD, that makes nervous people want to fit a steering damper, is gone..

    you got some pics of the H2 / RD ????? Be interesting.

    You'd never go hungry with Nigella Gaz.
    If it weren't for flashbacks...I'd have no memory at all..

    Yeah, ta H, I put that heap on a weigh bridge.. 160kg drippin'.. with all the road legal shit you see there, on board..
    Dunno if its the gyro forces from the big triple crank that settles the 'flighty' feeling RD high speed steering down,
    but, for sure, its a significant improvement for ~15kg worth of extra mill weight..

    These days it is regarded as a criminal waste of 2 valuable classics! Hah.. bullshit..
    & I still run an RZ 350 as a bloody commuter..


    As for the 500 triple, I 've owned/operated most of the variants.. the eariler - the quicker they are in stock form..
    ..but its not difficult to make 'em all run harder.. ..as stock, a good`69 H1 will speed-wise whip any RD 350 Yam earlier than an RZ..

    See here, 12.8 @ 99mph 1/4 mile, & 125mph top end speed.. http://www.kawtriple.com/mraxl/reviews/69h1pg7.htm

    One RD LC 350 I owned was an ex-production racer which had various 'naughty' components ( inc TZ rods),
    & it was a quick one, but still no match (in a straight line) for a similarly tricked-up triple..

    \ yes I agree, i had an H1a {UK variant with the 'coil' ignition} was only slightly slower than the mach3, and agreed quicker than a 350LC, but as I said my 350LC was a stephen's {the yam guru} tuned one.... and it was quicker than the kwaka, in fact in the early years of LC production, there were two 'club' tuned?? stephen's 350LC's at boxhill surrey and they took immense delight in chasing/beating CB900's. CBX's. Kwak 1000's round the 'circuit' and were incredibly quick on acceleration.

    Ta , never seen one of those ! Must be a great with the H2 torque ? From memory the stock H2 was finished at 7500rpm .

    Yeah, stock H2 is really a bit of a 'Clark Kent' in standard form, soft-tuned from the factory, but like most 2-strokes a bit of tuning
    wakes 'em up nicely.. if you check the dyno charts in the 1973 Superbike Shootout thread elsewhere in the classic section, you'll see..

    Yeah I have a mate who had one same as mine, the first blue model.
    But when I rode his, he had another 1000rpm to make it 8500rpm !!!!
    " Production" don't you know !!! haha.
    He won on it as I remember at Gracefield Wgton but sold it shortly after (probably before the protests started ??? lol)
    But yes stronger down low than the CB750 Honda of the time.
