Quite the education on O-rings. And I know that in high-reliability environments (mining, aviation, etc.), a mistake can be costly or deadly (Space Shuttle Challenger explosion). But for hobbyist like me, seems that just ordering from MG Cycle or Harpers is the solution. That said, I accept the challenge of finding the correct O-ring for the driveshaft. I have a spare with a broken O-ring, so will order all the O-rings that are close to its size and see what works. Seems like Nitrile would be fine for that application, FKM might last longer.

Wow - should be able to find anything there... but I was kind of hoping that most O-rings on the bike would be a standard size and that I could order an assortment and be likely to have whatever sizes I would need in future. Do you think that's realistic? But there is one very thin O-ring I would like to find - the one that seals the two halves of the driveshaft. Parker looks like a promising supplier.

I'm tired of buying one O-ring at a time and the associated hassle of finding the correct one. So I am hoping to stock up and save... and more importantly have them on hand when needed. As I understand it, Nitrile is most commonly used, but it degrades quickly, which is why many of have replaced the timing sensor o-ring on multiple occasions, and why we constantly lose the little bugger that serves as a brake pedal bumper. And Viton is a brand name, while FKM is the generic name for material used in Viton O-rings. And apparently FKM lasts longer in chemicals and sunlight. This is what I think I know, so please feel free to correct me. I'm looking at this set of 386 O-rings in 30 Metric sizes. Amazon link here. Does this seem like it would cover the majority of O-ring needs for our V11s? Any other recommended sets or sources that would be better?

I just sent you a PM. Hopefully, you will get that and be able to reply.

Good research. If you have a moment, maybe you could list the Moto Guzzi and Aprilia part numbers in the Encyclopedia of Compatible Parts.

Well... I am certainly not going about this project in the optimal order. After getting a lot of stuff "finalized" on the bars I remembered to check the steering bearings. They had a spot where they settled. The bottom bearing was almost totally dry and felt crunchy rotating it by hand. And look at the wear pattern in the race. New bearings, along with a better steering damper, should be a big improvement for handling and safety.

Visited the MEBC today (Moto Euro Breakfast Club). Check out the lovely new MV Augusta Turismo Veloce Lusso. Bodywork is the same color as my Scura's frame plate. And let's not ignore the Brutale 1090 hiding behind that...

I have a tool like that. Took out the gaskets in 5 seconds each. DONE.

My thought was that since I am switching headers it might be a good idea to replace the gaskets. And for some reason, I already had a pair of gaskets on hand.

Small update. Getting the Rizoma tanks, Spiegler hydraulic lines (black, of course) and Pazzo shorty levers installed. Speedhut is redoing the gauges... still waiting. I managed to destroy one bolt (and damage the other 5) on the cush drive side of the rear wheel and rounded 4 out of 6 on the brake side (despite plenty of heat and penetrating oil). The bolts that did come out had heaps of loc-tite residue - so I got help at a local machine shop. Now the wheels and bunch of other stuff are at the powder-coaters. I think I will have some play-time this weekend. A question: How important is it to replace the exhaust gaskets? I ask because I recall them being devilishly tricky to remove. I have new gaskets and I have a set of older pipes without the front crossover. Any tricks to getting the old exhaust gaskets out?

The Ram steel flywheel and clutch is available from MG Cycle. That's what I have in my Scura. But the 6-speed version is NLA and I think (always dangerous) that the 5-speed is identical with the exception of the transmission input hub, which is already installed on the Scura. I would talk to the guys at MG Cycle, or try to find a write-up on this site where somebody installed the 5-speed kit in a Scura (pretty sure it has been done). But gosh, there's nothing wrong with the double-plate clutch and that lightened flywheel. I'll send you a PM re the spring.

So you bought a Scura, brought it home and ripped out the flywheel? Next you'll be replacing the springs and stripping the crinkle paint from the engine, transmission and rear drive. This is the rite of passage for Scura owners. What flywheel and clutch will you install?

I've never had that experience on any motorcycle. I usually replace both tires when the rear is worn, because there is only about 20% or so remaining on the front. Maybe have a think about your tire pressures (I run 34 F and 38 R) or check your suspension or steering bearings. Or maybe you are doing a lot of hard braking?

Welcome and congratulations. May as well post up in the Scura registry too.

You can also use rattle can paints for plastic. With something that faded and with that much texture, paint might be worth considering.

That gear looks like a transmission input hub. If so, that one might be worth trying to identify.

Oh - that looks like only a paint problem. The fairing on mine had been ground flat in that spot, (but on left so maybe I have a good RH mirror). I sold the fairing to somebody who wanted to paint it to match a greenie.

That looks like a worthy project. If engine paint isn't bubbling now, it was probably redone by Moto Guzzi. The oil on the final drive is likely due to over-filling. From the pics, I'd guess the breather vent is the source of the mess. Those foot-forward, highway pegs? Wow. Personally, I'd remove those immediately. If you decide to freshen it up, I have a lot of stuff from a Champagne LeMans that I ended up stripping. The frame plates and rockers covers look fabulous in candy-apple red next to the champagne paint. If the fairing damage is more than you want to deal with, you could convert to a sport headlight with or without a flyscreen.

I would love to get back to the Alps. I had the opportunity once and made these videos. I was riding a BMW GS, so I thought it appropriate to use Scorpions songs instead of the GS sounds.

Setting sag correctly (assuming you have the right springs) makes a big difference. Now that it's set, you may as well ride the hell out of it till it sells. I recommend highway 33 out of Ojai... Best wishes for sorting out the other issues.

Why have you decided to sell it?

For powder-coating the rear wheel, do we remove the large sleeve? Bearings and inner spacer are out. The sleeve has a big spring clamp on the other side, which I removed, but the large sleeve seems to have been pressed in. The parts diagram shows it as a separate part, but the shop manual does not show how to remove it.

Wow - it looks perfect and all original. It should make somebody very happy.

FYI - I just pulled the bulb out of the headlight of my 2004 V11, and I found the spacer installed inside the bucket, exactly as you described.
