    Two-stroke bike won't start - help

    Not my R1 as its a yamaha and they dont break down

    But the young fella brought his first bike, a moped a 2 stroker and today he finally got his license and is chewing at the bit to have a ride and the fucking thing wont start

    so far I have

    replaced the plug, checked for spark
    checked compression (finger over the hole method)
    checked fuel (its getting fuel as the plug comes out wet

    and now I dunno what to look at.

    Any ideas

    any keen mechanics want a box of piss ?

    thanks in advance for the help

    Im a retard when it comes to bike mechanics, butttt possibly a battery, I had a similar problem with my cb125 bucket, had spark but no fire, replaced the battery and it fired to life,
    that or give it the old school bumpy bump start

    If you've got spark and compression and fresh fuel then the only thing I can add is if it's been sitting around for a while is it's possibly flooded the crank-case.

    I don't understand these moped thingies but if you can push it around in gear then whip out the plug put it in gear and push the fucker around until you have a coronary.
    You should see a shit load of fuel get pumped out the plughole and when it stops...or you have a heart attack...clean the plug and try from there.

    Also adjust or replace fuel cock and/or floats.

    sounds good, but no gearbox its a auto thing, so guess just push it around ?

    The beauty of a twostroke Quasi is it's basically just a pump.
    As long as the crank/piston is turning over it will pump the fuel out of the crankcase through the sparkplug hole

    Auto gearbox's are the devils work and i don't want anything to do with em.

    ok, I actually did that and turned it over for a while with no plug in, I wonder if that was the solution

    You must spread some Reputation around before giving it to DrunkenMistake again.

    hahhahahaha

    i would go for the honda bit......

    helpful buggers eh matey...

    timing could have moved, but i reckon you should clean the carb, make sure all the jets are clear... it will be something really simple....


    and i bet it is for you ya pussy

    Well shit Bret, or Brent or whatever. Don't spare the detail will you?

    Are you a newebe here?

    A 2 stroke you say? geee well now it's clear. oh its a moped, whatever that means.

    So it was going before? or no idea? c'mon.

    So how does the choke operate? Does it start ok with engine start? (indicating a choke issue).

    what is it? history?
    Don't you look at my accountant.
    He's the only one I've got.
