    right....

    haynes doesnt give a rod length,

    just has bore/stroke,clearences etc etc

    all crank selling places. (pm, donotlink, scooter centre/attack) none of them tell me a rod length for a standard stroke crank. (check for yourself if you dont believe me)

    closest info i have is that a 55 stroke crank has a 110 rod.

    yes i did check all these places before i posted this question, yes i did double check it when you bitched at me, yes i did search,

    yes i asked a question as im finding it hard to find a answer myself, and as you know the answer it would be nice if you share that info with me.

    no thats the 37 degree crank... wich has a longer rod..

    the stock conrod length off the top of my head is 105..... i think.... i thought the manual did have it.. along wiht all the toher info on the engine (gudgion pin dia and the like)

    hang on i'll just go whip my crank out to have a measure up......


    or not.


    con-rod kits should have a length listed on a scooter site. most the 52mm cranks will have the same length rod unless they have a barrel spacer needed.

    erm m8, i dont build pipes, i dont do crank rebuilds.. so why the fuck would i remember somthing off the top of my head somthing i read what, 9 years ago?

    as for you sending me your barrel.. i do work for people i like, not just people with money.

    That's just the kind of knee jerk reaction i thought i would get from a fool who did not understand my response, to calculate any piston port time area, and the basic fundamentals of any two stroke tuning you need to know the rod length
    its call trigonometry go look it up if that word is too long for you. He said he never takes much notice of it for his work.
    for the guy who asked the question its 105mm for 52, 54, and 55mm stokers
