    my Zip is causing me grief again

    everything is back together and done right, just wont start any ideas on what could be wrong?

    Carb is clean and correctly jetted
    oil pump is fine
    variator is back together correctly
    battery charged
    choke plugged back in
    all wiring done
    compression is fine

    ?????

    kick your bike about 5-7 times with a bit of throttle and take spark plug out and if its wet thats ok ...if not you have a fuel issue somwhere.....alternitvly put about a bottle lid full of petrol into the cylinder through the spark plug and if it fires this means you also have fuel problem

    and check the earth to ur coil pack but if you have a spark the earth is fine ...and i would get a new spark plug because the plug mite fire when out the cylinder but add compression it mite nit be stronger nuff

    Does no one have a brain ? Never put raw fuel into a two stroke cylinder. Will wreck rings. It could be the cdi unit or stator.

    wen im doing a plug check, instead of pouring petrol into cylinder, dip end of spark plug in fuel and put 5ml of 2 stroke oil onto cylinder this way you wont ruin anything as jonny said

    Then how is anyone going to learn to fix stuff if they don't do it them self. Maybe just give Full information next time ?

    easier way to check if its fuelling is if the plugs wet. If its not, then with the air box off, hold your hand loosly over the end of the carb (allowing air in) and crank it over. If theres fuel getting to the carb it'll atomize on your hand leaving a covering of petrol

    Actually, if you put a bit of petrol in the spark plug hole it wont wreck the rings, surely it will fine as 4 stroke run plain petrol in the combustion chamber? It's only the crank that needs oiling really...

    Well concidering that it's changed to fuel vapour in the cylinder not raw fuel yet it will damage rings.

    How is that relevant when the bike is a 2 stroke?

    Would've thought that there wouldn't need to be any oil in the actual combustion chamber, but yeah, my bad.
