I am in the process of restoring my '71 R60/5

Frame and tank are finally painted. Tank needed far more body work than I expected. I am pretty happy with it but noticed a couple small imperfections once the shiny black top coat was applied. Going to have to do. I will not be repainting. I left the fenders alone. They look good, not perfect but I like the character and the rear fender still has the factory sticker on it.

Couple simple questions: I hope

1) engine badges: I have seen these badges painted with the raised parts clear. Mine are not painted. Which is correct?
2) Carburetor Intake tubes: Again, I have seen them painted black and I have seen them bare plastic (or whatever they are made of). Which is correct?
3) Was the solo seat available as a stock option?
4) I have been using a soda blaster to clean up the hubs and other cast metal parts. It isn't working as well as I had hoped - especially on the motor. Any suggestions on how to clean that up would be appreciated. Jugs and heads (but not the valve covers) were media blasted by the shop I used for a valve job. The rest of the motor is pretty dirty.

I am not attempting to make this a show bike - just wanted to bring it back to life and looking good.

Thanks in advance for your sage advise. This is a great forum.

After some research I found a bunch of restored /5 similar in age to mine. It seems we do whatever we want. I am going to leave mine as is. No paint on either engine badges or carb intake tubes.

Is blasting the cast metal parts with a different media the only option I have for cleaning up the motor?

There can be some concerns

There can be some concerns about media blasting engine parts, especially the internals like heads, etc. And it depends on the type of media. If bits of the media are not flushed out, they can do internal damage. As for the outside, I suppose it's more common to use media blasting as long as passageways to the inside are blocked off.

If the engine is removed from the frame, using some elbow grease is effective for cleaning. You could still do that in the frame, but it's more difficult of course.

Have to be careful with the type of cleaner. Some have a mild form of acid and will stain the aluminum. WD40 is a pretty good cleaner.

The engine is eventually going to get dirty again...sometimes it's a losing battle!

Rub n'Buff

Degrease the casings and once dry and clean apply a TINY amount of Rub n'Buff in Silver Leaf colour very sparingly. An old toothbrush is perfect for the job - work the stuff well into the alloy, but do not polish or the whole thing will look too shiny. Rub n'Buff is a coloured wax used by picture framers, and their Silver Leaf is the perfect match for airhead castings - engine, gearbox, final drive, fork legs and hubs etc.

I was given this tip years ago by a Guzzi guy, and everyone I've passed this information on to has been blown away by the results.

That's sounds pretty awesome.

That's sounds pretty awesome. Can't wait to give it try. The engine is sitting on my bench so it should be easy. I'll try it first on a cover that isn't too visible so I can get the process down. I'll try to find it on line.

After all the work to get the rest of the bike pretty again, I don't want to have the engine looking dirty.

Here is a photo of my R25/3 gearbox with Rub n Buff applied.
Like Dan I am a great fan of the product!

Another option is vapour blasting if you are completely stripping the engine.

Wow!

That looks Great! My engine is on the bench but complete with the exception of the jugs and heads. I have no plans to take it further apart. The transmission is separated from the engine, of course.

This is a wax based

This is a wax based coating

Does anyone have any experience on engine casings? Concerned about standing up to heat...

No worries about withstanding

No worries about withstanding heat - I've put this stuff on cylinder heads with no issues.

If you find you've been a bit overenthusiastic with the application, a wipe with a solvent will remove all or most of it and you can start again. As mentioned earlier, moderation is key and the toothbrush application is the best way I've found - literally a match-head sized blob of Rub n'Buff, worked well in, will cover a huge area . You'll figure out what works best as you go, but start by doing a less obvious bit of engine etc. to get your head around the job. Another tip - wear workshop gloves or everything you touch after doing the bike will have silver fingerprints... and I mean everything.

Toaster stripes

Is there anyone who had an original non restored Toaster R 75/5 that can tell me if the original tank panels and side panels were painted or filled in with stickers?

panels

On my '73 LWB R75/5, they were painted. The battery panels were original, with some discoloration, adding to the patina of the bike.

Stickers would probably look fine though.

My bike had an original

My bike had an original sticker on top of the rear fender under the seat. It was beyond being legible but it was a beige -paper color with black print. It looks like it was closest in size to the tire pressure sticker. Can you tell me what sticker is supposed to be there.

Your web site only gives an option to buy in english currency.
