    aprilia sr50 wont start

    hi there i have an aprilia sr50 injection
    now the bike dont start
    if i take the airfilter off and put my hand in front of it
    it does start, and keeps starting
    but the next day it doesnt start anymore
    i just put in a new sparkplug
    anyway could this be injection related?
    thanks

    50cc's can generally be shit for starting, especially aprilia! 2005 aprilia - brand new, 1st day, wouldn't start for shit, and now, its doesn't start sometimes when its warm! i aint got a clue whats wrong there!

    I have put in a new sparkplug, and it did work ok for about 1 week. my mechanic says that it could be the carburator being dirty or something.
    It does start, but as soon as i go over 50 km it just doest want to go.My mechanic told me that it would happen within 2 weeks after putting the second new sparkplugg in.Any suggestions?

    maybe the gap in the spark plug is not the correct size...

    well sorry mate but to my knowledge (i hope im rite) your mechanic is talking shit.

    i thought that INJECTIONS didnt use a carb.

    did anyone else spot that flaw???.....

    Did it not cross anyone's mind that the air filter sponge could be clogged? if it doesn't get enough air, it won't start. if it gets too much air, it won't start. It may splutter a bit if you put your hand over it though.

    More than likely air-filter related. Check it for blockages, etc.
