when the ignition parts like the coil and the transistors in the cdi unit gets warmed up they dont work as well as when there cool,,,so a problem thats not there when cold will be there when its hot,,,,if the stator has a small fault in it when cold when it gets hot it turns into a big fault! the best way to find this fault is by swoping one part at a time till you fine the faulty part,,,or put it into the bike shop and pay through the knows for the fix? have you a friend with the same type of bike you could swop the parts with??? it a big big help if you have! i would start with the coil then the cdi unit,,,there the most likley parts to play up when they get to hot they go faulty!

I possibly have the same problem. I have narrowed it down to a fuel (lack of) problem. If you remove the seat and take off the vacum tube leading to the fuel tank cut off valve ( on the bottom of the fuel tank) you will be able to squirt a little fuel directly into the intake manifold,replace the tube and hopefully it will start instantly.no dought it will then stop repeat the process several times.
I suspect there is an electric soleniod system to deliver fuel on startup, I have dismantled the carb and am fairly sure the problem is with the electric needle system on the rear of the carb.
Hope it helps
