As some of the bevelheads know, this is the little cafe racer I'm working on. Just roughed together for fit at the moment and most of the fasteners will be replaced on final assembly. The area of the side badges on the tank had chunks of steel brazed into a perfectly good steel GT tank... I may have to bondo over it again (not happy about that) as it won't be easy getting it out.
Leave it as a 750. It is a round case engine which obviously never
came out as 860cc (900) so if you bore it out and add desmo heads you'll
spend a lot of cash but it won't be worth anything to anyone (but you).
The performance difference between a 750S and 900SS is very
marginal. Of course it could always be resleaved I guess but I just don't think it's a good thing.
Why not if you wish to gain performance, start with some
hi comp pistons, some 36mm carbs and improve the breathing in and
out? Later if you want, you could split the cases, add the right
conrods and anything else that you choose at that stage. Just don't
wreck a good roundie for the sake of extra capacity - you won't see
enough improvement to warrant it and these machines are becoming
very collectable in stock condition. Whatever mods you do, try to
ensure that they can be reversed in the event you wish to go down the
"original" route at a later date - or you may sell it to someone
who does. The other advantatge of valve springs is far less regular
maintenance than desmo heads - something to consider.

There a few other things to consider with this bike. Originality will be questionable at best. Frame has been bastardized by PO, but could come back by welding stuff back on. Tank I believe is hooped for life - that brazing is likely not reversable. Cases will have to be split next winter for transmission problems. I expect that the internals will be thrashed as the bike obviously has had a rough life under the PO's. One cylinder and one head have broken fins. Back to stock would require these bits replaced. On a whim I picked up 860 barrels, pistons and rings in excellent stock cond with little wear for dirt cheap.
I am 50/50 wether to build this as a 750 GT cafe racer leaving the possibility (although very unlikely) someone would want to attempt to return to stock, or build it as a 860 sleeper cafe. (I know, not much of a difference to warrant "sleeper" status)

ah, fak it. I'll figure out another way to get pics posted somewhere. Right now I only have this one. When I take a bunch more I'll set up an account with somebody...
When you post an image, it has to be a file, not a link to a webpage. If the link you put in between the image tags doesn't end in .jpg or something like that, it isn't going to work...
What you've got there is a link to another forum... put it between URL tags and you should be able to click on it to view it:
