Not sure if this is any clearer but this is with the valves in. Shame the transfer ports don't match the valves very well but at least it steps up to the powervalve window. Still tempted to try and get the dremel into there though
Well the barrels have been put back under the bench for a while, bit more progress on the bottom end to get it sorted just about ready to wrap it up and stick it under the bench for a while.
Looked at matching the valve windows up. I can't match the transfer to the valve with the kit I've got but as the valve is bigger and it's a step up for the gas flow so it's not all bad. Then I noticed I can match where the valve meets the exhaust casting, top edge had about a mm step that the gas coming through the valve would hit and the bottom edge was a bit out so at least I think I did a little bit of good..
side I haven't done yet hopefully shows how badly the valve meets the exhaust casting
side I have done, pic isn't great but top and bottom do match the casting now (honest!)

I'm stuck on the engine build again, waiting for some bits to arrive so decided to dig some other bits out.. forks legs needed some "refinishing". One leg done, one to go..
The original paint/lacquer finish was shot so I took it off with some thinners and really fine scotch bright. Then evened out the alloy surface with emery (some surface of the leg was machined smooth, other areas were still rough cast), took the scratches out with a graded polishing mop then I wanted a brushed finish so more scotch bright (tricky to get an even finish on it). I've used a silicone surface spray and I'm going to see how well it lasts, I'm hoping not to lacquer them again if I can keep them looking right.
There has been no degradation of the polished finish on any of the bits on my bike (hope it stays that way).
I used to use an abrasive impregnated rubber block (called a Loybock) to get a brushed or even a polished finish to quite badly corroded alloy.
I usually finish the surfaces off with a coat of canuba wax, I just wipe the surfaces clean
The Canuba wax was simple enough to find. Both forks need some more attention but I'm happy with them so far and handy to know I've got a good chance of keeping them right.. wasn't in the budget to pay for them to be redone
