cutting out

[delbert]

had a strange one today, been for a run stopped after 50 mile for half hour and it was a real pig to start . once started she ran fine for 50 mile or so then every time i hit over 4000 rpm she cut out , just like someone had turned the key off , then would come back in with a bang. did this a few times then all seemed well. have had vapour lock issues in the past , any thoughts or ideas
would be appriecated

Is your kickstand loose? Wouldn't explain the hard starting, but could be the reason for the cutting off and back on. Hard start on a 99 could well be your fuel pump vapor locking.

I would suspect fuel pump in this case, but the details are limited. How many miles on that first edition ?

its just covered 40000, will check kick stand also

Check your tip-over sensor also. I had the bracket on mine break so it was basically flopping around and would sporadically shut off. It mounts to the pivot of the gas tank underneath the seat.
