hey guys i got a 2002 speedfight 2 50cc AC and when i got it the exhaust was fucked so got a new one on it yeasterday but atfer i took the old one off a friend started my scoot got the new exhaust on went to fire it up and its not starting anyone know whats wrong with it?....btw i dont got a kickstart only button and it is sparking fine. Oh and another quick question can i jumpstart it using a car battery?
depends what sort of exhaust it is, what pipe did you have and what pipe did you swap it for? i suspect its possibly the back pressure difference of the new pipe, either that or jetting or some other fueling related issue but as youve only changed the exhaust id start there first :thumbsup:
when i got the scoot it had a tecnigas next R on it but it was rusty and had some holes in it do got a Giannelli Extra Exhaust With Carbon Can, could it be anything to do with my friend starting it up when it had no exhaust on?
could possibly be caused by starting without exhaust on, did he rev the granny out of it? if so there could be your problem. is the plug wet when you take it out after trying to start it? if its wet then fuel is getting through and theres no reason why it shouldnt start or at least fire a few times, unless your down on compression (piston rings gone) if the plug is dry then no fuel is getting through so try squirting some fuel down the sparkplug hole, if it fires when you try and start it then theres your problem :thumbsup:
did you change the jet when you fitted the new exhaust? and the rollers.clutch springs. try cleaning the plug make sure it isnt fouled up.check and make sure you havent caught anyhting when you were fitting the pipe and broke it.could have pulled a fuel line or somthing off.(you never know) or as someone allready said could be back pressure difference. hope this helps. cheeers ricky
Thanks guys kinda new to this and know fuck all atm my mate didnt rev it when there was no exhaust on just started it and then switched it off right away, gonna try jumpstart it tomoz soon as my booster pack is charged my old man thinks it could be cause my battery is low but gonna try all what you guys have said and see if i can get it started up and maybe take it on my first ride since i got it
starting it without the exhaust shouldent cause a problum.i have started bikes with out exhaust before in a garage i used to work at and they were fine. try jumpstarting it and let us know.
Used my dads booster pack thing he uses when his car is flat and nothing it turned over once and just sucked all the power out that pack so gonna get a new battery when i get paid and see what happens
Ok guys got it going today works fine now.... it was a blocked fuel line and low battery, thanks for all the help guys.
