Power valve issue
-
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.
-
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. -
@thechompster just out of interest, what spark plug are you running??
-
@mitch_350z iridium spark plug
-
@thechompster does it have the resistor in it the 'r' in the spark plug type as this can cause issues with the operation of the valve
-
@mitch_350z the one below. Br9eix.
-
Me too, br9eix
-
@thechompster my mistake, I meant without the 'r' lol if it hasn't got the resistor in it the valve finds a mind of its own. You can hear the exhaust note change as you ride
-
@mitch_350z I see. Where is the resister?
-
@thechompster I believe it’s built into the core of the plug
-
I guess it's ok as it ran great with the power valve working spot on for a few weeks. Just got a cdi off eBay and a servo so will try the cdi first and see if it fixes it.
-
Problem solved. It was the cdi unit. Changed that and it runs like a dream. Thought I'd let everyone know as sometimes people get it fixed and you never hear the outcome
-
@thechompster Glad you got it working bud, as I said previously, I guess these bikes are just getting to that age now unfortunately.
-
@calum thanks. Yeah sad really. Won't be many around after another 10 years.
-
@thechompster Zeeltronic make ignitions for these bikes so there is an aftermarket solution.
