Power valve issue
-
Hi peeps. I have A 2006 dt x sm. The issue is the power valve does it's cycle when ignition is put on but when I start the engine
it goes to the right slightly as it should I think but from there on it doesn't move at all even when revving it high. Any ideas? Havnt had the bike long. Did work well for a few weeks then occasionally but now doesn't work at all in high revs.wrote on 16 Apr 2018, 15:03 last edited by@thechompster check for corroded connections or loose connections

@thechompster check for corroded connections or loose connections
wrote on 16 Apr 2018, 15:11 last edited by@declan I did go over the connections the weekend. Some were a bit crappy so wire brushed them unless the connections are a bit dry. Didn't have any maintenance spray but will give them another clean now I have some. Would the servo make it go like that do you think?

Forced the valve open while engine running and goes like stink top end. Have noticed since I done that and tuned the ignition off and on and start engine it starts to move as it should for a few revs then stops moving again. I'm taking a guess it's the solenoid?

Are you sure the valve isn't just gunked up.
Would be worth dismantling the assembly and cleaning it thoroughly.

Took the exhaust off. A bit dirty in there but rotates easy enough. Goes through the cleaning process nice and easy so all I can do now is change the servo and hope it sorts it.

Odd that it'll do the cleaning cycle fine but not run right.
I'd be more inclined to say faulty CDI more than anything. I guess these bikes are just starting to show their age.

A friend had a faulty servo, sometime during a ride where the PV was open, it would leave it open. Other times just seem erratic. I believe the gears in the servo was toast.
