If it aint one thing its another!. Now that i got my headlight fixed my bike wont start It stalled out on me when i was driving and now it wont start back up, unless i push start it but soon after it will die again. Any help on what it might be? Would the Idle screws make it not start up? Oh yeah i would pull the plug to check spark and im really not getting any spark i also found out my electric start relay isnt there. So could it be my coils went bad? Both of them at the same time?

Considering you had an electrical issue, have you checked the charge on your battery and your spark?

I did and my battery was dead but i charged it and it held a full charge but the spark was not that strong i do know my petcock is messed it keeps leaking gas so i have it off the bike cause it poors the whole tank out so maybe my plugs are fouled? any other things?

Well, are you sure that it is the petcock that is leaking? It could possibly be a needle or float issue for the leak.

Might be a good idea to check that the points, condenser, and coil are all in good working order. That isn't really an area that I know much about though.

Yeah im sure its the petcock cause when i un hook it from the carb it keeps pouring gas out untill the tank is empty. ill check all the above.

yep, battery and flooding, that'll mess it up and even if the battery has 12v, the amps may be gone.

happened to mine in the pissing rain, it started missing and wouldn't run over 50 mph. new battery and voila!!

ill check that amps, But the thing is it will die after a coulple seconds of it been in nuetral than wont start back up again unelss i push start it. So i think my starter might be giving out since its not real stiff like my dt250 is but thats beyond the point of why its stalling out. But before i did the head light it ran pretty perfect.

also check you are charging. 14.5 volts @ 3k revs ( when it starts)

try disconnecting the head lamp and see if it works ok again!!

Ok i got some time to work on the bike and really got nothing done. I tried push starting the bike it turned on but was very faint and everytime i rolled the throttle back nothing, than it soon died i dont know what might be wrong with the bike. After i got the headlight fixed it wont start anymore. would a battery cause these problems? I keep getting it charged but they dont know how to test it and i dont have a muti meter. Any help would be great!!!

I wonder if the headlamp relay is faulty and causing a drain on the electrics?
