Make sure you're using a resistor type plug cap. Killed 2 CDIs before I learned that one.
Check the power valve too

Going to check out the powervalve close. New reeds made better throttle-respons and better bottom end. What symtoms on faulty CDI Did you have? Thanks!

I know you said it should be electrical but i had a similar thing on my ttr230 where it would start to bog at higher revs. It ended up getting so bad we had to leave the trail and i would stall. The problem was as simple as a pebble in the fuel line. But since the gas gas has a built in fuel filter maybe flushing the tank is a good idea.

Well, took a look at it today. Bearing on left side (gear pedal-side) has alot of play, the bellcrank-arm or actuator-arm has had a beating, will not rest against stop-screw, also there isnt tension in it, so it will not get back in closed motion.
Anyone have blueprints of PV and the inside of it? Ball bearings, 6000Z and 608ZZ? I have a fastener on the RHS pv bolt. Is this normal? Its not a fastener in the manual Does anyone know who sells new actuator-arms?

I've had the power valve actuator arm come off before and it was very similar so thought that would be it again, but arm all ok. |

I killed the RM one too eventually, really shows not to use non resistor type plug caps, I got one of the cdis from eBay in the end.

I did have an issue that went away which I believe as the ign coil which I replaced as I had a spare of an RGV250 road bike which was the same as many others will be. I retest with that coil inconclusively but seemed to happen occasionally or when hot. I don't want to spend your money but if there is a similar 2 storoke coil about it might be worth a try.
Obviously try another plug for giggles they can do weird shit like that and clean out carb jets and check something embarrassing like the main vibrating out
