Best powervalve setting for higher revs?

@scrimsmustang actually the dot in the cover is often way off. Exhaust should come off to make sure the pv is "flush with the exhaust port".

@scrimsmustang lol have you seen how far off those marks are I used to rely on them till I looked in the exhaust port pv wasn’t even close to being flush

@declan yes it’s pretty inaccurate. Perhaps on purpose as a power restriction
I remembered how it was when I was setting up my zeeltronic

@louis-james my thoughts exactly

I've never had any issues with the valve timing.

@calum shut up

@calum lol mines bang on too

[declan]

@finnerz89 nah your wrong

@declan jealousy doesn't flatter you

Maybe it has something to do with different years of PV having different drive shaft shapes (where plastic pulley slides on. Some are diamond and others are rectangular. 100% certain on my 2003 125 cylinder and my wr200 cylinder that the powervalve alignment marks do NOT align powervalve flush with exhaust port approx 8deg out from memory, best way to check is exhaust and head off with piston at bdc
