Removing Powervalve

[Arj256]

Would like to remove my power valve for cleaning up and inspection, as its removed when its re bored to have material taken off as far as I'm aware.
Looking at the diagram of it, it only appears to be held in by the clip and bolt under the cover? And once removed you should be able to pull the shaft out and the power valve can be removed? On a Mk2.

Mines not budging so just checking i haven't missed anything?

Once you remove the bolt holding the retaining clip it should just pull out.

Cheers for that, was hesitant if it was suitable for a little bit of force.
Had to make up a slide hammer for it and even that didn't work, meaning a few gentle taps of the hammer broke the build up of carbon to allow it to remove.
Its out now:

is it 100% necessary to remove for rebore?

I think i will make sure I do on my next one - but sort of curious for opinions.....

The PV needs to be in when the cylinder is rebored as it needs to be cut away or it will hit the new piston.

i think they just dremmelled mine in position,, cos I had to take it back cos when I fitted the piston the first time it did catch I bit as i slowly turned the engine over...

Fishtail,

Looking at the bore of your bike, it looks like they dremmeled the rebore as well, or maybe it was filed oversize by hand on Reclamation Street.

- mike is 20 sec in - actually I was searching for the episode where he does aerobics but didnt find it - that would have been soooooooooo much more suitable
