Given the sheer quantity of information in Palmer, and the nature of the subject, a few minor inconsistencies are only to be expected. The trick is to find them before they find you!
I'm hardly surprised that a minor part made in fairly small numbers is probably a variant of another, more common item.
I don't doubt Cotten's comments either, as far as they go; I'm sure the small number of possible buyers capable of constructing a manifold from scratch, would find this a straightforward, if time-consuming task.
It sounds as though the conclusion is that
1) any such item would need to be offered in conjunction with a suitable manifold so that the buyer can obtain a complete set of parts to build a functioning top-end
2) a buyer already possessing one of the possible variant manifold/ nut combinations will be able to identify whether their one fits or not, and why
3) there probably needs to be an additional component in the range, an adapter or alternative manifold to fit a modern carb, since 1 1/2" Linkerts don't grow on trees and aren't available in repop form AFAIK
4) item (3) may be common to BTSV manifolds, if they have 4-bolt carbs? YES if it us an adapter, NO if it is a separate unit
Repro cilinders for WLDR will mostl ikely need special manifold, WL will be too small, BTSV will be too big ( the cilinder intakes are further apart on the engine in case of a BTSV)
So yes, we will have to make those too.
About carburators: We have made reproductions in the past of the linkerts ( exact copies, so be carefull what you buy!! over 400 were made) and will make them again once we have someone that cna do it for reasonable price. Currenct problem is that the guy that made them wants sick money for more castings.
Secondly, Mikuni carburetors with conversionkits are sold by us for WL, and will therefore also fit WLDR applications. Available at any dealer of our parts, shitloads of these carbs go to germany for some reason..
To the matter of pistons: Use standard pistons, they will suffice, there are good japanese and indian ones in circulation, we are working on our own productline that will be based on the legendary TOTO pistons. Obviously pop-up will require modification.
About the UL/WLDR nuts, yes they are the same, but the manifold will differ.
About intakevalves, there is a special WLDR intake valve, people use it on WL cilinders (with increased intake bore) to emulate the WLDR cilinders ( without the bigger fins though) They will fit to WLDR cilinders without a problem, for WL cilinders it requires modification of the cilinder (also boring out inlet nipple to accomodate larger manifold)
