Soon, Nigel, soon;). Making front brake lines and junction for brake light switch at the moment, as well as oil tank mounts and wiring in Motogadget M-unit Blue.

Got sidetracked by sale of three bikes and a massive amount of spares and tools. I actually have some open space in shop and container. No Nortons were involved in the sale.

Phew…

Was worried there for a moment !

No worries, Nigel. This is a picture of the bikes waiting for the transporter to arrive, and some of the boxed parts.

Did one of those for my very last client ('78 Suzuki 750) and it seemed to me more trouble than it was worth (never mind the cost), by a factor of 10.

Sorry to hear that. Well, if I'm not happy with it, I can always go back to a conventional wiring plan.

It just seemed to involve more wire than a hand-wired harness, and then you are adding an expensive electrical/electronic part that can be a severe point of failure.
 
The Wood Rotax is pure motorcycle porn. Very envious.
Yeah, I think Ron made fewer than 20 of them in total. I'd like to have kept it, as well as the Gilera Piuma, just as art. But my road racing days are long gone, and letting others race them had lost it's appeal, so it was past time for them to go. They went to an AHRMA racer who was really happy to get them, so I'm content.

Hard having to make the decision to let something like that go. Nice that it went to somebody that will appreciate what they have, and not just flip it on ebay.
 
Finished up the front brake system today. The front fender is just a place holder. I'm planning to eventually use it as the basis for a suitable model, then pull a mold and make one in carbon fibre. But not until after I get it running. My plan is to get it to a rideable state to make sure it all works properly, then finish up the details later.

I did not read all 14 pages of this thread. If I felt shame this is where it would go.

Are those Ohlins(?) kit forks? What bike were they designed for originally?

You have a lot of unobtanium.
 
The first post in the thread mentions that the forks are Ohlins Superbike Forks, but not much else. I think I explained their history somewhere else in the thread, but I'll repeat it just in case. The forks are the ones Kenny Dreer used in his prototype bikes, the basis for the current 961 Commandos. I bought them from Kenny when he was selling off surplus parts after the design was sold to Stu Garner and the new Norton company in the UK. Kenny told me that he encountered them on a modern Japanese custom superbike, and decided he wanted to use them on his modern Norton update. When he asked Ohlins, they said they were custom made for their Japanese customer, and weren't available as a stock item. After Kenny got permission to use them from the customer, Ohlins was willing to supply them. I'm not sure how accurate my memory of that story is, but it's entertaining. In any case, Ohlins did eventually sell them as type FG 43 RWU. There were at least two versions made. The FG 433 was an off the shelf universal use set, while the FG 333 was the OEM fork specified by Norton for their 961 Commandos with RWU (right way up) forks. As far as I can tell, the only differences are that the in the overall length, plus any internal valving differences. Neither of them are supported any more by Ohlins. Their current version is the type FG620, which Ohlins refers to as their Retro 43 RWU fork. They are the latest cartridge design, with rebound damping in one fork and compression in the other. The ones I have on this bike are the FG 433.

Thanks for taking the time to put that information together and the fork model numbers. I apologize for not looking at least at the first page.

No problem. I'm a little embarrassed at the length of it. I've been working on this build now for a little over 6 years, but I've let myself be distracted by other projects too much. Time to finish it while I'm still able to ride.:rolleyes:

Awfully nice project bike...

Still kicking myself for passing on the forks that were on the original prototype, more like Cerianis...View attachment 82966

Were those Forcelle Italia (follow on company to Ceriani) forks? They look a lot like the ones I used on my PR. They have 5-position adjustable compression damping, and worked pretty well on the track. I still have them, and thought about putting them on the MK3, but then Kenny offered the Ohlins, and I couldn't resist. This is a picture of the FI forks on the PR.

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.
