Can you guys please help me..
i got a 49 cc mini dirt bike auto of course, and everytime i ride it and i rev it all the way it turns off, but when i let go of the throttle it turns back on and when i rev it and hold it, it turns off fully.. can you guys please help me and tell me what's wrong with it, thanks alot.

What happens if u gradually build the revs?

 

[anthonee]

it turns off after a certain point..

Probly something to do with petrol/carby

 

[anthonee]

so if i don't put the right amount of 2 stroke oil into the petrol does this happen ?

If your running to much oil it can bog down a bit. What mixture are you running?

 

[anthonee]

im running 155 mLs for 5 litres

 

[anthonee]

does anyone know what the problem is , my friend fell off it a few days ago but it looks normal..

30mil to a litre, might have a air leak, check your nuts and bolts..

maybe you twist to far and the Carib opens up to much and chokes the bike

i found on my pocket bike (same engine) that the spark plug was loose, and it would idle, then cut out if i rev it... try tightening it up, if not that it could be the choke as these lil ones allow a little bit of air but not enough if you rev it

 

[anthonee]

what do you mean by that

 

[mattbombers]

umm, tighten the spark plug...

and make sure the choke is off...

 

[anthonee]

anyone else got any ideas !!

 

[anthonee]

aww.. none of this is working, anyone else out there that can help me

 

[anthonee]

LOLOLOL

Yeah, it should have a lead hooked onto it..

i'd agree with that, sounds like she's bogging down. maybe in the crash there was a pull on the throttle cable, or a dislodging of the carbie throttle cable?
