    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.

          @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 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 I believe itโ€™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 ๐Ÿ™‚

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

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