That's normal.
With the engine running, the free play will tighten up.

Have had the powervalve rebuilt with new plate/bearings etc after finding the original was totally butchered.

Still have, what I would describe as, a loud ?clacking? noise.

Is this the noise the pv tension fix should stop ??

Person who did the pv rebuild has stated he left a bit of ?tolerance? there which may account for still having the LOUD noise.

IME, these engines make noise.

The powervalve flapper has a heap of tolerance in it, if it didn't it would bind up and need cleaning more frequently.

The clutch packs can make noise, the pistons can slap around a bit too. An alloy bash plate will redirect everything back up at you.

Add in a few vibrations, sloppy plastics, rad braces, a slightly misaligned pipe, and you get a symphony of sound.

Loosen the chain a bit and hear that slap too!

Don?t forget the clutch squeal. I have a rekluse clutch with a rekluse basket in my 2011 gasser. If I am a gear too high it will squeal like a pig. I have been riding it since 2011 and I have never ever had the slightest problem. I rode a 2018 gasser with a rekluse clutch, when I was a gear to high it would squeal exactly the same way as my 2011,otherwise in the correct gear the gassers never make a sound. My 94 CR 250 has a Rekluse clutch with the torque drive plate system and a Rekluse Basket, it never makes a sound even if I am two gears too high. Go figure.

Yes.
It is done at the governor, or bell crank which controls the pv movement as the revs rise.
The proper procedure has been described in detail on this forum.
You can find it with a search.
