They do look similar, but I'm trying to get more of THE parts that were on THAT bike (original prototype).

I could MAYBE be persuaded to install a pair of those white cast wheels, but it would take having a working 961 engine and those forks to make it happen.

Have you asked Kenny where the forks were sourced from?

You probably know the details of Kenny's development of the modern bikes better than I do. But I'm a little confused on which bike you are referring to as the "original prototype." This is the earliest picture I have of his modern Norton "prototype", and it shows the same Ceriani style forks as the blue Commando in your picture, but maybe a little more detail. They are a bit different than the old Forcelle Italia forks I have, but could just be a later version.

The only other of Kenny's modern Norton prototypes that I have a picture of is this one that he labeled as a 952, and it has the Ohlins forks.

If it's the Ohlins forks you're looking for (and It doesn''t sound like it is), Ollie still had a set of good used ones for sale not too long ago.

Actually, I suppose "prototype" may be arguably incorrect, but it is the FIRST rolling mockup of what the new Norton was based on, basically a VR880 chassis with a dummy 952 lump in it, shown in New York at the announcement (last photo I posted).

He sold me the bodywork, box-section monoshock swingarm with rising rate linkage, "big bearing" transmission cradle, "tight tuck" pipes, most of the parts to build a VR880 engine with Spyke E-start & one of 3 CF primary cases he had made, a VR front spool hub for dual discs, a set of FCR carbs, and I forget what else. By contract, he couldn't sell me the dummy lump (even though it wouldn't have done me any good), ALL of that stuff went to the biggest motorcycle world rip-off in our lifetimes.

Anyway, this is the bike I built, that represents the largest collection of the original new Norton's parts, in any one person's possession...

If my memory serves me, that Oil-In-Frame idea came back to bike Kenny pretty hard around that time, and he reverted at least two OIF VRs back to "standard tankers" for his clients in-warranty.

He gave me a pretty stern warning that rebuilding old bikes for people, and including a warranty, could cost me a lot of money. As it turned out, it cost me SOME money over 100+ major client builds, but not a net loss on a single one (only two failures of any significance, neither one major).

FWIW that's a plain MkIII engine that i reverted to right-foot shift, and I've since installed Amal 932 Premiers, as they actually work better. Notice the FCRs intakes have VERY TIGHT clearance to the frame web which I didn't want to cut out.

That's about enough off-topic discussion unless you care to @lcrken; after all, this is your thread...

Observation, not looking for trouble, but feel free to tell me I'm full of crap: ;)

Sure looks like the intakes used on that Blue 880 are at too steep (straight) an angle for that series FCR, and the frame used. An intake with a little more curve angle like what CNW uses and JS Motorsports sells would have given better clearance. Even a modified MkIII spigot manifold would have been better for clearance. I'm not sure if that would have helped with the performance, because there are too many other variables.

Only issue I have with FCR carburetors is I have to adjust the idle up on cold starts, and turn it down once the motor warms up. The warm up period gives me time to get my jacket and helmet on.

I would avoid using that steep straighter angle on the intake manifolds, if the same series FCRs are going on the project bike.

Ken, sorry to steer this thread off track again, but does that bike on the bench have Isolastics?

Not exactly. It is rubber mounted, but the mounts are not isolastic design. And the swing arm is mounted to the frame, not an engine cradle. You can see the two rear mounts a little better in this picture.

In this picture of an even earlier engine configuration, you can see the rear mounting holes that are large enough for a rubber mount, but not for the isolastic design.

And this picture of the earlier engine in the same frame shows the rear mounts from the other side.

The 952/961 bike went through several design iterations before it was sold to Stu and company.

This last shot looks like an almost standard set of power unit cases, but with a cutaway for whatever they were studying.

Lots of monkey motion with all those rear plates and stuff...
