Until the proper YZR500 Marvics arrive, I will have to make do with TZ250 Marvics and appropriately different spacers to fit in the guessitimated swing arm.

The spacers and different width carriers are to make up for the narrower TZ250 wheel hub versus the YZR hub.

Team Agostini OW86 YZR500 rear wheel has arrived :)

This was a bit of a surprise purchase sourced right here in the USA. Includes the rather interesting sprocket carrier setup - which when I drew from photos I got pretty darn close. Now I can get it perfect.

The wheel also included another magnesium rear sprocket carrier - so I haev 2 versions now.

I will use this wheel to get the dimensions I need to order the new Marvic wheel.

Speaking of being "on steroids", I suppose this is as good a time as any to let another cat out of the bag :)

Negotiations are underway.

Well, that is impressive. Looking forward to the details. It looks quite mean.

It's the real deal. Works motive power.

Details to now work out are the direction the engine restoration/revival will take. Essentially working out what is possible with this assembly.

This started as a GP clone but is now perilously close to becoming a real GP bike. A frame, swingarm and tank and you have the whole package. Difficult bits to acquire, but rare parts do have a way of finding their way to you. One piece at a time, but an honest to goodness GP bike.

Yes - this is probably the single most exciting (and intimidating) piece I have found and if all proves to be the way I hope.... its one of the pieces that may change the very heart and soul of the bike.
