@2stroketerry Yeah I just want to rule it out bud. When the valve is lined perfectly with the exhaust port (I recommend taking the exhaust off and double checking, disconnect the valve completely from the loom so that it cannot operate. Then go and take the bike for a blast up a dual carriage way. Should pull hard to the red line with compromised power below 6K. If that's the case, then you know the PV isn't setup probably.

Some upjet a lot with a different exhaust, eventhough its rarely needed.
How big is the mainjet? Try a stock sized. -
Hi @Calum when I turn my ignition on the powervalve goes through cleaning cycle then stops with notch in pully lined up exactly with the hole behind it. The bike is an import and supposed to be fully working powervalve, has plenty of power bottom end and can feel the powervalve come in around 7,000rpm. Just won't rev past 8500 or 65mph for some reason, don't know if silencer is holding me back and no idea what the silencer is just says 3MB on it. The hole in silencer is smaller than it looks from the side, should I get another silencer ?

Hi , yes going to do what @Calum said and remove the exhaust and make sure fully open then unplug my servo from the harness. Can't do it at the moment as my bike is outside and it's -4 and snowing so will have to wait for better weather, my girlfriend won't let me bring it in the kitchen to work on it. She went mad the other day when she got home and found the kitchen table and chairs all took apart, just need to bribe her.lol
