bogging past around 4500rpm. 06 EC300

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

Check the power valve too

Using BR8ES. Non-Resistor plug is B8EG/S? My plug-cap seems to be for a resistor plug due to large cap-hole inside. May because of resistor cap on the plugs.

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?

Oh bugger! My EC250 sounds exactly like that
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.

What year RM 125 CDI box?

[motopsycho87]

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
