Power valve issue

[Jens Eskildsen]

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??

[thechompster]

@mitch_350z iridium spark plug

[Mitch_350z]

@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

I've always ran br9eix on my bikes with no isses.

I think that's the one at least.

[thechompster]

@mitch_350z the one below. Br9eix.

[Irongamer727]

Me too, br9eix

[Mitch_350z]

@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

[thechompster]

@mitch_350z I see. Where is the resister?

[declan]

@thechompster I believe it’s built into the core of the plug

[Mitch_350z]

@declan yeah it is

[thechompster]

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.

[thechompster]

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

[Calum]

@thechompster Glad you got it working bud, as I said previously, I guess these bikes are just getting to that age now unfortunately.

[thechompster]

@calum thanks. Yeah sad really. Won't be many around after another 10 years.

[Calum]

@thechompster Zeeltronic make ignitions for these bikes so there is an aftermarket solution.

[thechompster]

@calum that's good. Glad someone does

[Calum]

@thechompster And ignitech
