    Default Cd70 euro 2 carb on chonda 70?

    A.O.A
    Guys I m facing some problems with my default carb(dyl dhoom 70 2012) like poor mileage 40-42 kmpl and cold start problems..
    So I was thinking of installing cd-70 carb as my friend cd 70's average is 70+ with most of time in economy zone and 65-68 with hard acceleration...
    I want to know will it increase my bikes mileage and effect its pick n top speed?
    Your suggestion are appreciated...
    Thanks

    bro dhoom engine is 88cc and cd 70 is 69cc ..
    carb cd70 ka lag jaya ga laikin jetting karni paray gi .. and even then it wont be ideal situation ..

    i also faced this issue with my dhoom 2009 model .. and i replaced jets and problem solved .. but i got a dozen or so jets of same number because even number was same they were not precise in the specs ..

    first u should try a 100ml method to verify ur bike economy .. search on of my thread on this method .. only if u are getting poor economy then u should change jets ..

    buy 35 pilot .. but match both jets .. they should be ditto same on outside ..

    and 78 main jet ..

    what is ur cold start problem ?
    i also had this when i used stock carb and stock jets ..
    replacing jets did helped in cold start issue ..
    my issue was that it wont start in first kick .. it would take considerable number of kicks .. after jet replacement it would start within first 4 kicks .. also use 20w40 oil .. like havoline ..

    now since i have a bigger cylinder and qingqi carb .. it starts on first kick be it 5 in the morning ... if it doesnt starts on first kick it starts on second kick .... last time i did a piston swap and i havent checked its avg precisly ..

    It start at first kick but turn off within 10-15 sec even I have 1/4 race given... and after turn off it starts after 8-10 kicks..
    If I pull the choke then it starts after 4-5 kicks..

    Is qingqi carb good for avg? Are there any improvement in pick, top speed performance after replacing stock carb?
