hey if i have to crank my bike many times really quick to get it started with full throttle but once started i can start it no probe for like 24 hours and yesterday full of gas started coming out of the expansion chamber near th cylender? what would you say that is bad fuel mix or spark plug?

[banfordg]

@davison1021 Every time you kick the bike though you're cycling unburnt fuel through the system, sounds like this is building up in the crank case hence fuel coming out of the expansion chamber. Get a wiring diagram, a voltmeter, and a service manual and check the output from the stator when you kick it over. If it's not what it should be then get yourself on ebay! Tip: Remove the plug and the tank off then flip the bike upside down and crank the engine to clear the old/unburnt fuel. ;)

@banfordg well i found that their was supposed to be a spring that holds the fleng and header together their was no spring and i had flodded it to the point wher the expansion chamber was full first time starting a dirtbike i fixed it since i welded the flenge and header together i dont think thats bad now it starts one crank thanks for the help tho i subed

@davison1021 Nice one, glad you got it sorted. Hey, best piece of dirtbike advice is to always wear a helmet.. Enjoy!

I think it's so funny that English people pronounce "Z" as "Zed".

You say "A" as "A"

You say "B" as "B"

In-fact you pronounce that whole alphabet just as it appears.... except "Z". Where or when on earth did you decide... Hmmm... let's add an "ed" to the end of "Z"?
