Didn't BMW say it was for safety in the event of an accident the rider was less likely to get brake fluid on him
Or something like that

In post #11 I said “I might stick a bore scope down the bores”.
Scope creep already…

No, you are doing it correctly. Look now and know rather than know after you have a problem and the work is the same anyway.
What is sad, is this head should have been on the twins day one. Nothing technically would have prevented it. Imagine it on
the Trident. Hey, don't trudge it Rudge it!

Well I must say, it’s lovely to work on. After all it is actually brand new !No, you are doing it correctly. Look now and know rather than know after you have a problem and the work is the same anyway.

I decided to strip the top end for a few reasons.
Main one is the powder coating is so hideously thick on these things. It’s like wrapping an insulating jacket around the head and barrel! I’m planning on stripping it and getting it re-done in something like Cerakoat.
And I know a racer bloke who makes nickasil barrels, excellent things, so am thinking of putting a set on.
These subtle mods combined will make a huge difference to cooling. And not having the liners removes few potential TSS known failure modes.

Flow porting it?

IF applied correctly!
I would agree that a like for like thickness would likely give like for like results.
But it would be IMPOSSIBLE to apply paint as thickly as it is on this head and barrel !
Look at the attached pic, and this is just the front of the head. How thick is it gonna be where it’s welled up in between the fins etc? In between the fins on the top of the head is where I saw it the thickest when I stripped the powder off of my old TSS head.
Some TSS’s have been known to drop valve seats. My hypothesis is that insulating the head in plastic may well have caused unduly high head temps which contributed to this.

I don’t think anodizing is the answer, but there are a number of specialist ‘heat dissipating’ coatings available these days which I will be exploring for head and barrel.
I stripped my old TSS engine of all powder and left it like that, it looked great, but I want to keep this one looking more close to factory spec.

I will not be doing anything heavy, but it would be rude to put it back together without tidying things up in there a little bit.Flow porting it?
I have decided not to use the Bings, so am now trying to decide between 30 and 34mm Amals. They had 34 as stock, but the inlet stubs narrow down to 30 to match the head, after which they open up to split into two ports, and I’m thinking that keeping 30 all the way through would aid charge velocity ?
But, on the other hand, Triumph had use of an engine brake dyno, so it’s just possible that they put the 34s on for a reason !?
