To go on the 888

marvin

I'm sure that I have some. Let me check and get back to you.

I've got a pair of grey ones. I think they are for an 888. The rear is slightly modified to fit under the RR tank. See what Marvin turns up first.

BABA

These are 851 engine's version (machined to cut the rear belt cover part)

888 version is slightly different (here std uncutted)

The left side part was also used on the belt side with a plug screw on 888 R to replace this part.

Hi Baba

So not a part number then? Just what teams did?

R91 was delivered with standard and uncutted black road parts (24710061A).
When you see cutted parts, it is not a "special" part made for race bikes (except magnesium version), it is just a modified road part (as I did for my Racing 91).
It was made by the factory or team/tuner directly (it's very easy to do, you just have to have a milling machine).
Even for magnesium parts, the mould was the same as the road part, and only material injected was different.
Sometimes you find uncutted magnesium parts for sale too.
They were in magnesium only on Factory bikes at the begining (and probably on some customers bikes if you pay for it).
They were already machined in 1988 on Factory bikes, but still in aluminium, not magnesium.
It seems on pictures that they used magnesium parts first on the last version of 1990 factory bikes (the first version with higher exhaust pipes and X ram air in carbon fibers, appeared for Monza 90),
R93 had 24710701A parts. On the scheme, it looked that they were uncutted too.
But probably they used a previous drawing to illustrate the catalog. On pictures of R93 assembled in the factory, they were already cutted.
They were in magnesium in 93 on customers bikes.
I'm not sure how it was on R92, I had no pictures enough detailed to see if they were machined and in magnesium or aluminium (I haven't the catalog parts to compared references too).

I misunderstood, thought you wanted belt covers. 😄

Now I'm confused. Do you want belt covers or those plate covers?

851 Plate covers, I can machine as per Baba's post.

Thanks Marvin

BABA

So here are dxf file for machining them if you have access to cnc machine 😄

You have the drawing to make a block for fixing the part and the outside line to cut it on the same dxf file.
I gave you the plate and the camshaft cap if you want to cut them too.

I have a pair ff of a later engine(just like the one that BABA posted. You will have to machine them. They are silver, not black.

You can have them if you want to pay postage. If so PM me your mailing address (I may have t but not sure)

marvin

I just found a set of 851 heads that I forgot I had. They have those covers on them too. Just like the ones in your picture. Either will work. Your choice.

Thank you everyone as luck would have it I sourced some less than 10 miles away.

Baba, thank you for the files, I'll see what the local engineering shop can do.

Thank you again everyone.
