how do i open my powervalve fully?

in the photo the red sealer you see the allen cap bolt that is in the middle you undo this then take the exhaust off then get a pair of long nose plyers and then turn the ypvs spool but at the same time you need to put your finger up the exhaust port chamber and when the top of the ypvs spool is flush with the top of the exhaust port chamber then this means the ypvs is fully open then you still need to keep your finger up the exhaust port while you do up the allen cap bolt but remember to reseal again as in photo

as above

thanks alot mate!

You need a full licence and a couple of hundred quid to make it a 'full power' model.
