Well, I didn’t have a lot to start with but very pleased to say that the only thing stopping me getting this yellow desmo back on the road (since 1981 apparently) is a numberplate and knowing what the fork oil capacity is? Can anyone here advise?

Congratulations, that's a really nice job I think everyone on here knows just how hard it is to get a Duke single up to the standard you have achieved here, now take it out and dirty it .......I think the forks from memory hold about 170ish mls.
Cheers,
George

Thanks George, I be happier with it if I could find a Desmo head (original is missing in action) but the springer will do for now.

So apart from my 250 desmo my other Ducati is a 1974 350 Mk3 which I bought new, nearly 50 years later I still have it and its still my favourite bike of all time ( and I have had many) when I bought it I wanted a 350 desmo ......but such a thing could not be got so the Mk3 was my second best. Over the years I had slowly gathered together all the bits except 'the head' to convert the Mk3 to a desmo look a like but never actually did it because I didn't have the desmo head. So with years of watching Ebay it became obvious that fairly regularly desmo heads turned up in America and I eventually carefully purchased a totally bare 350 head casting for not a great deal of money and then subsequently acquired all the bits to make it complete at quite a lot of money. During this process I noticed that in the States I never once saw a 250 desmo head.....I only ever saw I think three maybe four 350 D heads, but I have seen dozens of 450 rt heads I presume because the Americans bought loads of 450 rt off roaders and wrecked them.... I saw so many rt 450D heads I seriously considered buying one welding it all up and re machining it back to 350 spec as a viable way to get a head for my bike .I might have mentioned in some other post re your bike to go for a rt head I think that's maybe the only way you will get one without spending a fortune.

I can’t even seem to find an RT head George

Are not the 250 and 350 desmo heads identical?

Pretty much the same ....but I believe the squish profile is different between the two...or so I was told??

The same part number is in the factory lists.
0609.92.350 for both 250 and 350 Desmo heads.

heads are the same . bevelshaft is longer on a 350 .

the only head that has a different squish band angle is the 350 Sebring

Thanks all, that's another little Ducati urban myth (in my head only) dispelled.
