O.K another try. (dont mind it at all Brenton)
Hello Tony, is this the once started Vtwin (crankcase) from Adrie ?
I remember that one.
Herman Noort & me also made one.........1st of April front cover of the Cheval, way back then!
Anyway, yours is the real McCoy, very good looking !
How did you 'solve' the problem of mounting the belt when both mainshafts are in place & fixed ?
Old Britts made up a belt tensioner to overcome mounting problems. (see pic)
I want to do it like you have in your picture, is it just a case of patience when mounting by wiggling both pulleys home ?
Featherbed on the picture was made by Old Britts for Billy Joel, his got the starter canted forward.
At first I wanted to do the same but found that a elec. connection got in the way of the top gearbox mounting lug.
So I put it on like you have (Old Britts relocate this connection)
Behind the clutch basket I fit a reworked Steve Maney outrigger bearing.
It's turned by 25° to make way for the bendix arrangement, it's welded by now.
Old Britts have the outrigger bearing incorporated into the starter cradle (see pic)
