I'm dreading pulling the engine down, not so much because of the difficulty but more of what further damage $$$ I'm going to discover, anyway I've made a start Camshafts are out, I've measured the Shims and thankfully there's enough margin to sort the ones with less than .03mm clearance.
I'll get the Head off tonight and maybe the Cylinder if my mate comes over and gives me a hand.

Meanwhile, new Meter Bracket and Blinkers have turned up from Webike, so thought I'd try and fit them up:
Rears - PO dodgy'd up some front headlight/blinker mount, so the only hole showing below the ducktail is the round hole for the headlight, do I try and dremel the diamond shaped hole in the bracket or grind away the plastic on the blinker to fit the round hole?
     

Fronts - Fitted the blinkers and attached the headlight shell, check out the gap between the meters and the shell, something weird going on here...Any clues??

Looks to me like the PO open the meters and spot weld the clamping rings together again.

Yeah I was wondering about that, not sure what he achieved as both screws in the Speedo and one screw in the Tacho are rattling around...
By cutting through the ring does that allow access to the screws?

Kia Ora Glen, the jointing ring can be gently eased open by going around the rim with a suitable tool, takes time and patience so not to damage it, then you will get full access inside the gauges.

These rings are available new for stupid money but you have to fab a bearing roll-on jig to get a good press fit.
Post pics later.........

Here is a pretty good tutorial on opening the meters. Sadly all the rather important picture seem to have gone to the Botophucket black hole.

Kinda rare those face screws would wiggle out on such a smooth running bike? I see them wiggle out/loosen on the Buzzy two strokes but never on a 4 stroke. These are the removal tools i've been using for years. A length of appropriate schedule 40 PVC, modified needle nosed pliers, modified vice grips for recrimping and an old Z1 sprocket clamped to the bench. Yes there's fancier ways, especially the bearing/roller recrimping tool but done correctly even with these tools ya never can tell the difference.

Hi Scirocco, good jig 😁 you should sell these in kit form, probably a market for them 👍
