Hi All In need of some assistance please. I had a rectifier fail and it fried the PGM/ECU on my AR 1998. I have had the PGM repaired by Nick in Greece and ready to reassemble and also have a new rectifier. This occurred some time back and I did not take pictures of the rectifier loom routing. As the...

That's the listing for the guy in Greece!!
Where?

Thank you for your reply. I have taken the power valve cover off along with the cover for the PV motor. The PV motor is not responding. However if I rev the engine towards full throttle to the point it bogs down and then manually operate the PV via the motor it overcomes the bogging down and is as s...

Carb off again and cleaned including fuel tank and filter. Main jet replaced with 150 as fitted before (premix). Pilot jet std. Check for air leaks completed and all reassembled.

Gammakeith Now run the engine to running temp. The engine still dies/bogs down from 1/3 to 1/2 throttle. Manually turned the power valve and engine revs much higher. So my thoughts are 1) test voltage to power valve motor 2) assume PGM unit faulty Any other thoughts? http://www.crm250.com/forum/mem...

Thank you Keith. The volt meter seems a good idea

Thank you for your info. Much appreciated.

I guess connecting up and testing the voltage max output runs a risk of potentially damaging the unit if quality is an issue from the start.
Im not sure if the PGM/ECU is already damaged from failure of removed unit. We will see!

New rectifier now arrived and earlier than expected. While trying to fit a pattern part I notice the cable is a lot longer and the protection shroud around the cables is larger and therefore doesn't fit in the area alongside left hand side of air box where I think they were located! Help please 1) d...

No I haven’t.
Tested rectifier and it appears faulty.
New one ordered and arriving early January. Once replaced I’ll be checking power valve operation mechanical/electrical.
In the mean time I have replaced pilot and main jets.

Well this looks like an interesting site to belong to with lots of info! Having searched the site for info, maybe someone on here with some technical/diagnostic experience can help me with my current technical woes. Recently took the bike for MoT. En-route I noticed that when accelerating beyond cir...
