That'll do it! 
I've got the Tony Foale software if you want any calcs done on the geometry Yazza. It's a useful tool when swapping out front ends.

Didn't know that existed, can you just add in what bike the frames from and what the front ends off or would you have to measure it all?
From what I can find on t'internet their rake and trail is vey similar. Obviously the forks might need soft springs and lighter oil but at least I'll have a proper adjustable setup with twin calipers then. Probably overkill but will look nice anyway

I need to get that myself, handy for the modern classic grid! I've got the Tony Foale software if you want any calcs done on the geometry Yazza. It's a useful tool when swapping out front ends.

The version I have requires measurements but it is a few years old. Not sure if a newer version has a bike library.

Yep it does fit, it's not that big the tyres a 160. Think the wheel is 4.5 inch, only prob is it needs some work to get central but it's do able, there's another mito knocking about with one fitted.
I'm probably not going to buy anymore bits now unless a bargain comes up, need to focus on making this collection of parts I already have fit together!!

Dry build coming up?!
Going to focus on getting it rolling as soon as possible. Hoping to get the rear wheel/spacers modded and the front end fitted up then next month or so get a shocker and the mount kit bought. Gonna take longer and cost more than putting the mito stuff on it but that's not what I want at the end of the day. 
Little update..
The real engineering is starting now..At the moment I've got the sprocket carrier for the Rs250 wheel at the engineers for some machining, this will basically bring the offset for the RS250 wheel right for the mito swing arm to bring it central so I can spacer the other side. Theres one other guy who's fitted this wheel to a mito and he machined all the cush drive out deeper in the wheel, cut his rubbers in half and all sorts, didn't want to do that and had a eureka moment last night there's more to it than a little machining but I'm not giving everything away
The frame is going to another engineer on Monday with some larger equipment to bore the headstock out slightly to take RSV mille taper roller bearings, lots of meat in it, and it's only slightly larger so no worries there. The only bugger with it then is that the Mille steering stem is too long, so I'll either have to shorten what I have, or press it out and have a new one made. Both do-able.
Before anyone says why not use the mito stem, yokes etc. I've thought about it and don't want to. Once the stem and bearings are sorted I just want to bolt the whole mille front end on, no f
king about with wheel and caliper spacers etc. Infact I think with the mito yokes it'd be too tight anyway.
Obviously shortening it by cutting, pressing a centre piece in the welding it all up will be cheaper and I can just crack on with it, it's been dne quite a lot from what I've researched too. But it might always be in the back of my mind that I should've just got a new one made...
Anyway, not many updates but still lots going on

Ryan,
Good luck, it's going to be a cracking project, plenty of hurdles to overcome, although theres a ton of info out there.
One thing to check before you press on is with the front end change, double check the Mito and RSV steering geometry before you go too far. Rake, trail, offsets etc. You might find a combination of the parts creates a poor front end set up, so you might need to retain some parts over others. For example, if the RSV triples have a smaller offset, you will affect your trail dimensions massively, as well as possibly causing the wheel to hit the rad or overly shortening the wheelbase etc.
