    Hi there (again)

    Is anyone able to suggest what the symptoms would be, i'm not too sure how to check but i'm thinking my nrg issues (previous post) are due to this.

    Thanks for any help people

    sorry i don't think i explained myself properly. The bike seems to run okay and start ok. Just when you open up the throttle up fully it starts to feel like its bogging or running out of fuel.
    I tried it today with a manual choke and it ran ok. Started ok. When warm i turned it off and the revs evened out. But it runs best with a 65 main and std idle and needle in std position. So i'm getting closer but wanna burn the thing out somewhere. Getting really fed up with the piece of shit

    Im having the same problem with my choke, it starts perfectly, warms up great but one i open the throttle fully it just seems to be a bit jittery and sort of starts spitting im either thinking this is my jet been blocked up, air filter been too dirty or even my spark been too fouled, anyone have a good idea or should i just check the ones ive been thinking about :confused:cratch:

    Cheers anyway guys :good:

    I had the sam problem with my Yamaha Aerox 2000, its got a Manual Choke, and it werent running fine, so i took the jets off, cleaned them and blew them with an air line, took the reeds off, and blew them off, cleaned everything up, and put my old airbox on, it ran like shit with the other one, i took it off yesterday when it started playing up, and it ran fine, but sounded like the choke was on, and Hated Full throttle, so old air box on, and it run fine, i cant hear my exhaust much, but with the other filter on, she run like a good en, im going to upgrade to a 17.5mm carb instead of a standard 12mm, racing 50's kit
