whoop whooop whoooop ,stripped carby at track still no luck,gunna do it again at home but after 15 kicks i could smell fuel im hopeing it aint electrical ,its got a 2.5 hrs old iridium plug and on the way home i forgot to turn off the fuel and it was damn bumpy id expect it to overflow after an hour or more of drivin home{bike in back of ute) but absolutly no evidence of fuel leaking out overflow.What do u guys reckon fuel or electrical and by the way iv,e just rebuilt topend(resleeved)3hrs old and it had sat for 14months before i bought her.Any opionion would be f#*#*N great?????

Check for spark before you do anything. Sounds like a sudden failure? If so I would doubt fuel problem in that case.

Might help if you state model and a little more about how it quit.

its an ec 250 2001 , after a 1 hour ride it was missing in revs down low and up top i put it down to having the exspansion chamber ding removed(when i bought it ,it was smashed in)i presumed the old owner may have adjusted the air fuel mixcher,upon inspection i couldnt find the air fuel mixer?i let the bike rest for 30 40 minutes started it up for a mate to ride and in the next 40 seconds i could hear it slowly loseing power then just died.its got a brand new iridium spark plug which i,d thought would last more than 3 hours and i ran the engine in using the 15 minutes ride 15 minutes rest 4 times when i stripped the carby there was no rubbish in the float bowl and i removed the fuel filter as well i didnt check the spark plug and i had a quick look for loose wires and checked the spark plug lead .i hope this is enough information. cheers mate!

Was the spark plug dry? Was it black and wet, go 2 steps down in main jet and replace the spark plug (ordinary br8es)!
