thanks!

Did a bit of painting and polishing today… painted and lacquered the clutch cover, and rear spring, and put a coat of lacquer on the cam belt covers which I had decided to carbon effect dip… not everyone’s cup of tea I know, but I like the look… The silencers came up really well! there were a few marks on them that would have niggled me so I decided to polish them.

as an aside, while the spray gun had some lacquer in, I finished off some cheese boards I have been making as Christmas presents for friends... its got me a few brownie points.. the fruit and spices are encapsulated in clear casing resin.

Lovely! You can't beat a bit of shinola.

I bought a (cheap) set of cored and polished silencers shortly after buying my 900, but chappie had polished off the anodising from the start with a mop and the result is not only hard work for him but as soon as the mop penetrates the hard anodised surface it digs in the ally. They were quite rippled and I could never flatten them out.
I've recently done another set and started with an orbital sander with a flat pad to get the anodise off. This left them flat and polishing was a doddle.
The easiest way to core them if you want to go that way is just to drill holes in the end plate between the inner and outer tailpipe. Much easier than chopping the cans all up, you just keep adding holes until the required tone is achieved.

Chopping boards will be Elm?

that's exactly what I did! I used a DA with 320 grit discs on and sanded them first... they came up really well...

not sure what the wood is, I found it in a mates loft while I was helping him do some ducting... he said it had been there 30 years!

Darkness · 12-12-2020, 06:14 PM

Looks a lot like Elm, but most of that came down forty five years ago.

Started the rebuild… first job was to put the frame on the engine, easy job, I held it, my wife popped the bolts in! I then fitted the headstock bearings, which I have replaced as there were small sighs of pitting, and they are cheap. I pulled them in rather than use a hammer, which also means you can give them a good tighten and bed them in nice and hard against the register. Its starting to come together… Was also playing around with the image of the engine…

anyone know what those forks are and how much oil I should put in each leg?

That engine deserves a coffee table all to itself!

I'm no expert, but they look like early M900 Showas. If so, then the workshop manual recommends 457cc with an oil level of 79.4mm.

Luddite · 15-12-2020, 12:18 AM

Just had another look at that picture of your forks - are they the adjustable ones? If so, they may be from a 900SS and, if that's the case, then the oil capacity/level would be different - 440cc and 108mm respectively:

Are there any model numbers stamped into the bottom inside edge of the forks perhaps?

The coloured nuts on the top of the forks suggest Marzocchi to me rather than Showa? Marzocchi were standard fitment to some of the Monster range in the mid to late 90s.

The Showa forks I’ve seen have ‘SHOWA’ cast into the ally fork bottoms, next to the wheel, so easily seen when the wheel’s out, but less so when fitted.

Thanks guys, here are some close ups... any idea what they are?

Well I did say I was no expert!

Darkness is correct; that logo shows they are, in fact, Marzocchi. Unfortunately, the only data I have on Marzocchis are for my Evo. I'm sure someone on here will have the info. you need though.

slob · 15-12-2020, 10:16 AM

They're Marzocchis from the the line and circle (fork and wheel) logo above 'CA.'

this might help

"Haynes says for the Marzocchi forks it should be:
90mm air gap and SAE 7.5 Oil"

I think Flip has the Marzocchis on his Monster and he's done lots of work on the suspension, so he may have the information you need*. (By the way, aren't the Marzocchis the ones where one fork controls compression damping and one rebound?)

*Or, indeed, slob!

Definitely adjustable Marzocchis, I have the same on my '96 900 monster.
