inlet tract spacing

[Dav]

My verniers are at work but peering at a plastic ruler and measuring the engine side adapters on my 41s gives 52mm b/w adapters (outer surface) and 98mm centre to centre

[M.V.]

Lucky Dav is here!

I forget that my old barrels are still at the engineers

Anyway, whipped the tank & airbox off, getting a rough figure of 98.5mm, bearing in mind I'm not very good at math & I've had a few red wines

Thanks guys,

I will go with 98.25 and spread 'em to that.

A mil or so either way will be fine the rubbers are flexible after all.

Actually measured it myself today with verniers , as good as anything to 100mm flat.
attached is a pic with a plain ol rooola.
There would be a little to and fro availble but for reference, round it up to a hundred.

cheers

The pic with the roola didn`t happen!
