Machined Clutch Casing
 

The machined open clutch casing (casing not clutch cover) on the corse bikes look great and expensive:(

Please can someone tell me if it is possible to get the standard item machined? If so is it expensive:puzzled:

Is there any downside to fitting this to a road bike?

both my 890 and baby R have machined primary casings,not sure of total cost because both were done during full rebuilds,i think the machining costs were about £80 ish

Contact Neil748R; he's done it for his own bike and a couple of others and is very happy with it. He's a perfectionist so it must look good!

Downside is a lot more crud to get into the clutch

upside is a lot more dust can get out :P

JHP used to do an exchange. I remember paying £60 some two years ago.

As to crud... well I guess you let crud out (have you seen the inside of closed cover?) as well as risk crud in. However, I ran a 996 for over 20K miles with a machined casing and had no problems. It is arguable whether it is worse than a vented clutch cover. I am not sure it matters. It looks good and will ventilate the clutch better.

I was thinking of doing this over the winter to my 749.

Anyone got a decent pic of a machined casing ?

True, but lets say you hit the gravel trap;)

there are lots of what if's on track.
like what if some plonk takes you out your bike flips 10 times and ends up in a pile of bits the other side of the track then catches fire.
I don't tend to think about these possibilities that much.
maybe I should maybe I shouldn't :eureka:
:P

The clutch cover on Logyk's FWR 888 is machined...there is a pic in the 13th post down on this link here

Probably the easiest way is to get another cover and get that machined, keeping your std for the day you sell........Dont forget that the testastretta covers are different to the older engines!

Thank you for all of the replies.

Just got a casing off ebay last night for £ 19.00 inc postage:D

Fitted a red 48 tooth basket and speedymoto face plate last winter (from cornerspeed).

The fully vented casing looks great so I will let you know what it costs once I have asked about.

Thanks again Mike

If you still need a pic of a machined casing, have a look at the Magnesium section on Tecmoto's website, there's a clutch housing on there.
I've been considering machining the one on my bike, easier said than done though, as the remaining sections of the housing are tapered. Not too difficult on a C.N.C. mill, but a bit fiddly on a manual m/c.

You get the right one?;)

This is my original Ducati cover after I machined it. Much tougher than carbon and have never had any problems with muck and bullets - AND as Jon will attest I have visited the gravel trap with it - admittedly not as often as him tho.........:sing:

John......I think it is the machining of the casing which is under discussion here not the cover :)

It looks like the right one

Can this be done in any machine shop?

Anyone know someone near Cambridge?

The difference is to do with an oil gallery that will sieze bearings if fitted to the wrong engine. what engine do you have and whats the cover from?

Bit irrelevent as I forgot to post the bloody picture!

You can get the older version altered Andy. I got hold of a mag one and didn't realise there was a difference. Trusty old Johnny hackett made the alterations for me.

I might have seen the gravel more time than what I would have liked, but you are the grass king thats for sure:D

Its planned that it will go on a 748S 2002.

When it arrives I will compare it with the one that comes off.

Cheers for the advice:o

Why not go the whole hog,both my bikes have had the magnesium DP items machined & fittec by JHP,they look really trick!!

PS John Hackett said they were a pain to machine,they destroyed a number of machine tools in the process!!
