    I have a ZX Pipe, and my main jet is a 72 WITHOUT THE 70's I KNOW. WAY TOO BIG. & I will probably have my rollers about 4.4

    what air filter are you using the stock air box ? or open filter ? you only need a stock air box the open filter will just drink fuel. a 72 main jet on a 50 with a zx and air box is WAY to big you only need a 60-62.
    With the 70 fitted a 70-72 is about right but if its a new kit your best of running it a bit rich for the first few hundred miles to avoid a seize. and like i say ive put 5.5 in mine ytou might find 4.5 a bit light your best getting it on a dyno to get it set up perfect

    Just a thought bud but did you read through the info that came with your kit ?
    If you did please say you washed your new kit really really really good with clean fresh petrol i mean all of it and poured petrol in all the ports i just washed a brand new one that looked really clean out the box but once it was washed you should have seen the crap in the bowl all tiny bits of metal like sand trust me you dont want that in you nice new 7u0 kit ripping it apart

    yeh every kit ive ever bought weather it be a big bore kit or a stock part for a ped or bike has always been in a sealed box and every one i have washed with petrol trust me a brand new kit is far from clean they look clean and feel clean but you wash one in petrol and see how much crap comes of them.
    If you wasnt supposed to wash them with petrol why does it say that in in the paper work for most kits you buy to wash them in petrol thoughly before use

    the metal dust that is left over from manufacture is so fine like grains of small sand it will work like a cutting/seating compound and cause damage to not just the bore but the crank aswell once it gets into the moving parts it will just rub away its probably why most peaple who fit 70 kits not long later are on here saying my crank bearings are fucked
