so i was to meet a friend of mine about 15-20 miles away. i take off from home on a cold bike,make it to my friends about 20 minutes later. we decided where to go and that we would stop at the gas station to top off tanks. i pull in and top off my tank,talk to another friend who also got gas and got a cold drink. we then got on the bikes and my buddy's statrs his and takes off to the stop sign.i turn on mine ( wait for the little engine light to go off) and then it happened!!! all it did was crank and crank and crank... and so on. i let it set for about 15-20 minutes and just when my buddy was on his bike and heading to his house to get the truck and trailer i tried it one last time and it fired right up and ran perfect all day long. my issue is it has done it before several times and left me settin til it cools off...but it wasnt even hot.WTF!!! any ideas... anybody else have this happen? thanks for all input guys.

 

Are They Friendly Spirits ?

 

Sounds like vapor lock. Not sure, never has happened to me, YET?!

 

bad switch?

 

a couple posts in here about bad thumb switches.

 

Look for the service bulletin posted on 2007 big twin starter issues.

 

well guys idk myself i dont think it could be vapor lock i had just filled it up, could be bad thumb switch and doubt its FRIENDLY SPIRITS!! haha good one though

 

Several posts on here discuss bikes with tuners, do not wait to hit start once bike is warm. Turn on switch, crank her over.

 

well last time it done this i finally got it to fire up after waiting an hour for it to cool off then rode it to my dealer 60 miles away and they did alot of diagnostics on it and finally got it to do what it did to me and they ended up replacing the crank position sensor and all was good til the other day..surelly its not that again..

 

Sure it could. It could also be a coil goin' open when it's hot. Got spark?
