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. -

@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?

@thechompster it’s possible the the teeth on the cogs may have snapped it worth taking a look

@declan cogs are fine as just changed the chain so checked them both.

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?

@thechompster It's a motor on these. So could be the brushes.
Are you sure the valve isn't just gunked up.
Would be worth dismantling the assembly and cleaning it thoroughly.

@calum it could possibly be gunked up but would it not move when you turn the ignition on?

@calum do you have a link for how to remove power valve at all?
@thechompster No, just take the two powervalve end caps off. The offside powervalve housing has a bolt to keep the two pieces together, make sure you don't lose the locating dowels as they're prone to falling out. You'll want to lubricate it with WD40.

@calum ok thanks for the help. With give it a go.

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.
@calum yeah I guess they are.apart from that it runs lovely. Will change the servo. If that doesn't do it just the cdi left I guess.

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.

@jens-eskildsen ok thanks mate. Very helpfull
Will try another servo then and see what happens. -
