    Hello everyone

    I have a Yamaha TZM 150 CC with single CYL 2 stroke engine
    I want to do some hardcore modification on it
    my plane for the modification is

    1st step Replacing the cylinder component
    Re-Ground the CYL
    Forged/custom Piston
    Forged/custom CON ROD
    Forged/custom CRANK


    2nd replacing the carburettor with an electronic fuel injection kit, made specially for the 2 stroke bike, My carburettor ID is kind of small the inner die is 28/mm
    I will be replacing it with a bigger throttle bode size 34mm
    this kit can be supplied with 1 or 2 injector, but the company support told me that for my engine RPM one injector is ok (my RPM RED LINE start on 10K)2T_EFI_Kit_mid.jpg

    3rd install cold air intake with K&N sport filter

    4th upgrade is the exhaust system, since my bike sound is really damn high, so i will be installing a branded silencer from FMF, and will try to do a custom silencer for the whole exhaust pipe - like this one . ( the pipe will be wrapped with silicone sheets and rubber/truck inner tube )

    That is it for now

    So guys, and suggestion or idea will be much appreciated

    Do you guys now where I can re-ground(re-bore) my Cylinder !!!

    Regards
    Hany

    Thank you Zhu for your replay and advice, yes i mean Re-bore the Cylinder, coz i think it might not be soft from inside, so probably this will cause leaking and it might be one of the reason that my bike is super noise
    BTW while i was googling about this i found one of the Chinese forum show the progress of the re-boring for the same bike, but there was not info about the location where this progress has been done

    the photo shows a company in wuhan which is a specialist cylinder boring company
    and the phone number should put you in touch with them
    looks like they did a pretty nice job of that cylinder as it obviously had a fair bit of damage

    good luck with your project hany and keep us updated

    I have checked the link, looks professional, but i have question related to my case if i re-bored the CYL, will i have a problem when fitting the con rod as the diameter of the CYL will bigger..
    will i be able to find 0.10 piston rings set for my CYL or what shall i do !!

    Also about my bike model i think its kind of known in china as ZF150-2, also i can find in Taobao many parts for it, but all standard

    Guys, does any buddy now if the FMF silencer is good enough to silence my super noise bike, of course this will be after wrapping the hole exhaust pipe with silicone sheets and truck inner tube..

    Any suggestion will be appreciated
    Thanks
