Try it with the kill switch disconnected or at least removed/hanging from bars (if you havent already!)

Sounds like most things have been suggested and checked, the only thing i'll add is regarding the reeds.
You say in your opening post you changed 2 of the 4 petals. I recently had similar issues where it wouldnt rev out cleanly in the powerband / sputtering at higher rpm. I changed and checked a few things, but it wasnt until I changed reeds (all of them) that it went away. Not sure why you only changed 2 (perhaps the other 2 looked ok?), but apart from a tiny little chip in the corner of one petal on mine, they all looked fine. Maybe the two you didnt change are giving you problems?

If your compression is low, the bike will not rev into the powerband.
Have your checked piston and rings |

Regarding piston, its a 15-25h old piston, clearences are good, piston-rings are well within spec (<0,30) and the problem was also with another piston. Going to cut open the electrical wires from stator and up, order a new coil and disconnect everything but stator, coil, regulator and CDI. Also going to add a new sparkplug and clean the carb, for the 103th time. Better safe then sorry. Thanks for the answers! Ill keep you posted

The voltage regulator should have no effect on the ignition system; it only clips peak voltage for lighting.
For sparks: 1) Single exciter winding on the stator plus wires 2) Pulse trigger outside of the flywheel plus wires 3) CDI plus wires 4) Ignition coil plus wires 5) High tension lead plus spark plug 6) Grounds for the engine and coil etc. The flywheel magnets could be weak if the flywheel has been smacked or otherwise beat up by a previous owner. Breaking up at high RPM suggests a bad wiring connection or corroded wire or shorting out due to bad insulation. There's got to be an answer somewhere.

You said the bike runs fine for 15 minutes then bogs? Then it can only be electrical. It's a very common symptom of a failing coil somewhere or cdi,run well cold, but something expands and shorts or disconnects the circuit somewhere...

Is your gas cap vent clogged with dirt? I Had a similar problem with a bike before with this issue. Same symptoms as u described.

after the rebuild, I fired up and took it on a 45min run. 15min out of the 45min, it started to bog as usual. As Neil said, I am guessing its a bad connection somewhere. Does someone have a picture of the wiring to the cdi box / ie. from the stator? As I said in page 2 here, I think previous owner had it wired wrong. Fuel runs freely, and nothings clogged. Ive got a lot to do these times, so i am going to the shed when I got the time for it.
