Sleeping Beauty , how could you????!!!

[made2care]

Took her out for another "TEST" run today. Wanted to see what she could do, was going 55mph and opened up her throttle , she took of nicely up to 80mph real quick, let off of throttle and she died. I coasted and pulled to the side of the road. Put her in neutral and tried starting her, she would not start. Remembered reading on this forum somewhere to open the gas cap when this happens, not that it would get her going but I thought I would try it. Started her without gas cap on, no luck. Tried again, no luck. Placed gas cap back on and tried again. Shazzaaaaaam!!! She started up!! What just happened?? Did it have something to do with me throttling up to 80 mph?
Thanks for helping.

I can't remember what you've already done to the bike. It sounds to me like either a weak or non-functioning fuel pump or a plugged fuel filter or plugged fuel line.

How full is/was the fuel tank at the time of the episode?

My uneducated guess is you are getting a sufficient amount of fuel to operate under low-load levels of operation. When you throttled up, you used up the available fuel in the carb bowls, causing the engine to shut down. Fooling around with the gas tank gave your pump enough time to refill the carb bowls and re-start the engine.

Of course, everything I wrote is pure speculation.

You probably starved the fuel system.Plugged gas cap.remember the fuel pump only operates as the engine is cranking and if the system were empty,it would take quite a bit of cranking to get enough fuel to fire it off.You probably put the cap back on just about the same time as the carbs got gas.
Run the bike with the cap loose to test the put it back and see if it quits again,just to verify its causing the problem.

Will try gas cap trick.

Why not clean the gas cap anyway? Turn it upside down and fill every hole and crevass with WD40 (I use Walmarts Tech lubricant) let it soak over night, blow it out with compressed air. You won't believe the amount of gum turned to hard lacquer over the years that blows out of there. Change your fuel filter too. If you have changed the fuel filter it could be clogged already because of the bike sitting with fuel gum and rust, change it again, and again.

I soaked it last night in CLR . Lots of gunk.

It wont be long till Sleeping Beauty puts on her ball gown, and really shows you how she can dance.

Good job with the CLR, another awesome testimony for the stuff (sarcasm). I've bought the stuff, used the stuff, it has never done anything even noticeable for me, CLR does not like me. Gunk came out? Good job anyways.
