    right i will give you a spec list so far

    endy power pipe
    5.5g rollers
    yellow clutch springs
    polini foam air filter

    all was well with the bike without the filter apart from a leaky exhuast gasget (which i need a new one so if anyone knows where i can get one would be good). But now i have put the air filter on its running like poo it boggs out on full revs and before the speedo needle used to go off the clock on a flat road but it says at 40mph some people i know are saying a 80, 82 or 84 jet and ajust the scews on the carb to suit but i cannot find any where sell delorto jets.

    any help i good


    plus this is a 04 neos so how do i derestrict the cdi unit as im not shure how


    thanks

    re-fit the airbox and burn the filter.

    like wobbly basicly said refitt the airbox filters are only suited to some 70s (and 172 etc) with bigger carbs and good pipes

    if you insist on keeping the freeflow then u will have to upjet by about 5-8%

    your plug colour should be a coffee brown colour after a normal run.

    the bike should rev to it's peak power band when you open the throttle all the way no matter how fast it's going.

    right i have put the old air box on and set up the air screw but it still is not how it was. It REALLY slows down from 50 to about 40-45 how can i get it to keep the speed on a slight uphill, where as it used to just go up it without losing any speed at all

    oh and should i put the pin back down in the carb as i moved it up a notch when it was running really bad??

    right ive put it all back to what it was and it is still doing it i will try to explain best i can

    all is well on a flat road up to 50mph and then it runs out of puff BUT before all the running probs started it went off the clock

    what can i do ive tryed letting mor air and petrol in but still no good does it need upjetting

    it is really frustrating as it used to be the fastest ped out of all my mate now they blat past me please can someone give me a clue as to what to do next

    air leek mabey, but im deffo guessing worn belt/roillers aswell. just because it was fine befor doesent mean the belt is in the same state. rich jetting and heavy rollers make for some seriouse belt ware (remember the belt is under more tention as the variator is comming out too quickly and squashing it)

    as belts start 2 ware they become thinner thus causing them 2 be looser....

    has the belt passed its cell by date??
