bike died out at 70mph, need advice.

Hey, i was doing 70mph on my runner 172 and the bike died, just like i ran out of fuel was verry werid then i tryed to kick it up, it wouldent fire. so i kept trying and it wouldent start, so i put the choke on and then it started??? the bike was red hot so why the hell would it start when the choke was on ? i thought maby the flot got stuck in the carb or something and starved it of fuel.

P.s my bike has a 25mm delorto carb on it


Thanks

 

running lean i would of thought...hence putting the choke on helped (richening up the mixture)

also remember a lean mixture burns a lot hotter, which could of been why your engine got real hot....richer mixtures burn much cooler....the temperature guage is a handy tool when trying to assess jetting you know

 

Well the temp was normal and i cant see why it would feel like it ran out of fule and then wouldent start if it was lean, it would siese wouldent it ?

 

that is what you said orginally, and that is what led Dave to say what he did. Besides partial seizes/ " nip ups," on bikes with automatic clutchs aren't so obvious or dramatic as with a locked/manual clutch.

 

my bad and it dident sises becuse it was like it ran out of fule, graguley bogin out.

 

if it was me, I guess given there is spark and compression, and the plug after cranking was dry, I would have the carb off for a strip and a thorough clean and inspection. Especially the float bowl and contents including the jets.

 

iv took the carb to bits, its all fine, the bikes running fine now, havent got a clue what happend

 

ok thanks for the help btw how reliable are temp gauges on old runners XD

 

haha good, cus mine hardley moves, thought it was broke! LOL
