I'm with you bud.  Who can ride a desmosedici to it's full potential on the street?  I'm also not a fan of electronic controls... it's cheating.

Itís just so raw and visceral.
A Desmosedici is like Dwayne ďThe RockĒ Johnson soaked in perfume.
The GRISO/MGS is like Mike Tyson soaked in sweat.

Earlier the year I bought a Racebike Chassis and tank that was built by Andy Sidlow from the UK in the late '80's. It was raced for the '87 or '88 season before it was retired in favor of a spine frame. It was an impulse buy.

Fascinating. What provenance do you have to positively track it back to Sidlow? The brazing certainly looks like his trademark work, but the stuff around the swing arm pivot is not brazed. I see you have a different swing arm to that in the first pic which shows a floating  FD.
Regardless, it is an interesting frame and I will follow with interest, good work so far.

Provenance came from the fellow I bought it from, and Confirmed by pictures and Amedeo from raceco. From what I gather, it was a raced for a season and was a testbed. It was abandoned when the spineframe became available. It was twitchy and the second owner performed the rear swing arm was change. Some or the rear work will be revised. This is not some world championship winning racer. I had a Lemans 1000 motor with a hot cam in it, a tranny, forks and wheels. This frame became available and it was really different.

I'm not disputing it for a moment, in fact I think its a cool project & I would like to follow it. I met Andy when he passed through NZ a few years ago, he stood in my workshop and gave me great advice regarding mt replica Egli Vincent frame. By all accounts, he made more than a few, & I have seen one which arrived here about that time. We were surrounded by Guzzis in my shop but I dont recall Andy mentioning that he had ever had involvement with a Guzzi frame for anyone, but then we were engrossed in Egli talk at the time. :laugh:

I didn't take it that way at all. I had no clue who he was until after I bought it. As far as I'm concerned, it is a weird one off race bike frame campaigned by Raceco UK. for a short time.  I still don't know much about him, there is not a lot of info about him on the net. I'd love his E-mail to send him a picture when it's done. You wouldn't happen to have that, would you?  :grin:

Maybe he can be located through this Facebook page?

https://www.facebook.com/raceco.uk/?__tn__=-UC*F

I really know nothing at all about him other than what I'm learning from this thread, but I would like to know where those cool Astralite wheels went and if I can have them  :azn:

Yes, he is very elusive. It took a considerable amount of time & effort to track him down 7 or 8 years ago. Then he passed through NZ and returned to the UK and disappeared again. I havent heard of him since. He chooses to live in the shadows.

At a point in the bikes history, the frame was modified poorly. The Original frame was made from thin wall T45 steel tubing. All the recent stuff is being cut away and tossed. Everything will be put back as originally intended with Chrome moly 4130 tubing. My Buddy Tom Hull is on the job!

I'm lucky. My buddy Tom Hull ( local euro bike fixer ) really likes fabricating and the creative process. He saw the two distinct types of welding and said that shit has to go before I had a chance to open my pie hole. I'm more of the vision / parts accumulator. My last project and a lot of these parts came from his Dad who was THE guzzi dealer here in phoenix up until about '97 .

Triple clamps with short head stem.

I like the work on the triples, As you may recall, I've had my eyes on those for a while now, so I like to keep track of them - I want them now even more than before :-)

Which fork/fork tubes do you plan on using? Are there ones like the LM1000, but shorter?

Good to see progress. I was informed recently that T45 tube is European mm sizes, have you procured 25mm? (or was I given duff gen?) It will be great to see it repaired with the same material that Mr Sidlow used to build it.

So, assuming the battery won't go there, where will it go?  Is there enough room in the seat hump for it?

under the seat hump is one possibility, and building a box for the electronics under the tank is another. I'm leaning towards the seat. That's where it originally lived.
