Hi, The oil cooler from the Hypermotard 1100 Evo is much bigger, both rows and width. Also the Scrambler 1100 have a oil cooler that is bigger.
I wouldn’t be too concerned about using the earlier style oil cooler. When I last change my belts, in removing the oil cooler to facilitate removal of the horizontal cylinder belt cover, I snapped the “L” bracket off of my oil cooler. The rad specialists next to Baines racing couldn’t help and neither could the guys at Bicester Heritage who make oil coolers for Spitfires. The bracket looks like it is riveted to the bottom gallery but it’s spot welded. So I had a nice 4mm hole in the bottom of the bottom gallery. OE parts price was circa £250. My solution was to remove completely and drain and clean the the cooler with brake cleaner. Find the biggest steel pop rivet I had, 5mm, drill the “L” bracket to suite and also the hole in the bottom gallery plus the top of the bottom gallery. The pop rivet then goes through the “L” bracket and through the bottom and top of the bottom gallery. Before riveting I applied Araldite to the bottom and top of the bottom gallery. So, the point I wish to get over is that even with the bottom gallery severely restricted or possibly not functioning at all I have never seen the oil temp any higher than before the mishap. I know the DS is a bigger lump by 10% but don’t see that as a concern. I will be over at Silverstone in the near future and will ask Geoff Baines about their twin cooler mod which I suspect was developed for their project Imola. Finally, congrats on a superb thread about your conversion of the DS and your meticulous attention to detail. As to aesthetics, we appear to see things slightly differently.
Thanks for the input guys. I’ve been looking at Different Ducati Oil Coolers on EBAY, which if nothing else is a great resource for finding images of specific parts, and have identified that yes some later models have a similar style Oil cooler with a couple of additional rows. Those fitted to the Multi 1200 appear to be priced a little better on the used market than others. The more I look at this I’m thinking the 1000SS Oil cooler is in completely the wrong place above the Horizontal cylinder head as per the early Monsters, it interrupts the airflow to the rear cylinder, and because of a build up of pressure behind it possibly also has a lower volume of air flowing through it. The Baines solution for the Carbie 900 utilising two coolers, one down either side is a good solution which I might be able to replicate. In the spirit of this being a Ducati ‘Bitsa’, a couple of Scrambler Coolers which are quite small and mounted vertically would appear to work. The earlier SS models had their Oil Cooler below the Horizontal Cyl head, and it was a common mod on early Monsters to replicate the SS position to keep them cooler. I don’t have any experience of 916s etc, but the 999, 1098 etc have nicely tapered Oil Coolers that fit even lower down in the V of the fairing, in fact I fitted one to my old Carbie 900SS project a few years ago. An option is obviously to source and fit one of those, stupidly I sold the one I had recently thinking I’d never use it. I’m wondering though if I have a ready made solution already sitting in a storage box in my workshop. The Multistrada 1000DS used the same engine as the 1000SS but the Oil Cooler was mounted up high in the nose cone under the headlight on much longer Hoses. And I just happen to have a complete set up ready to try. The Oil Cooler itself is just a little smaller, but the longer hoses and better air flow up in the nose should make up for that. Combined with the better airflow around the engine because it’s not being interrupted by the Oil Cooler in the original position could be a good solution. I have already mocked up the actual Oil Cooler into position and it fits really nicely ½ behind the bottom vents in the nose cone, and ½ below it. I’m hoping tomorrow to get time to try the hoses and see if they could be used. Another option is to try the SS Cooler up in the nose, but that would definitely require custom hoses. I do have a concern though. The Multi Oil Cooler is fed and drained from the bottom, not the top, so is reliant on the viscosity and volume of the oil to ensure it fills the Cooler under pressure rather than just flow across the bottom gallery. The angles of the ports and hoses mean it wouldn’t be easy to flip it over. I think it will be OK, but I’m sure others will have a view.
Hi, If you need bigger oil cooler in the nose cone check out the Multistrada 1200 oil cooler. A total different approach is found on the MotoGuzzi Griso Which uses a sidemounted oilcooler with a airscoop. On Ducati 1000/1100 we could mount it low on LHS. https://www.motorcyclespareparts.eu...2005-griso-v-ie-1100-motorcycles/oil-radiator
Hi Nasher where did you find the info to convert the forks? Is it an easy swap or do you have to change all the internals? I was thinking to fit a pair of 848/1098 forks on my 900ss i.e. as I have already the radial calipers.
I worked it out for myself, with a few trials and examining various disassembled forks, and have posted how to do it on here somewhere in the past.
Does anyone have an image of a Multistrada 1000DS with the front fairings removed so I can see how high up the Oil cooler is mounted. As mentioned above I want to mock up a Multi 1000 Oil cooler on my 1000SS but want to ensure I don't mount it any higher in relation to the engine than it would be on the Multi. I don't think there is much danger of me doing that, but want to be sure. Thanks
I also managed to have another play with the Multi 1000DS Oil Cooler and Hoses. NOTE - Please excuse the state of the engine/bike in these images, it will be cleaned up properly and painted at some stage. The standard Oil cooler in position does block airflow to the centre of the V and Vertical Cylinder: It's easy to see how much better the flow of cool air would be with it out of the way: So I fitted the Multi 1000 Hoses and cooler which was just cable tied in place to see how they sat. What I stupidly hadn't thought of until it was in place is that it needs to be high enough to allow full fork compression without the Mudguard touching it. So it ends up tucked right up behind the nose cone: It needs to come forward about 1/2 inch from where it is pictured to give better clearance to the forks on full lock, and in this position I could probably just get away with refitting the standard nose cone and headlight, something I think I'll end up doing at some stage. But, it would only really be fed with air by the two small slots in the nose cone, and I don't really want to cut any more and ruin the look. I could add some mesh and spray it White, but I wouldn't be happy. So need to cogitate on it a bit more. Although, looking at the images the airflow looks a lot better on screen than it did in the flesh.
Have you considered feeding the hoses through the slots and mounting the cooler in front of the fairing?
Thanks Borgo. I think if I was fitting the Cooler 'outside' I'd want to go aftermarket so it looked a bit better, and it would also need longer aftermarket hoses. But I really don't think I'd like the look. I know a lot of 80's/90s Endurance bikes had Oil Coolers exactly how you describe but I don't think it's for me. I need to spend a bit more time looking at the nose cone. Your images have made me think. Perhaps I could make the two slots a bit taller but keep the same style. Increasing their height by 50% would increase air flow massively. And perhaps some ducting. Anyone have a spare fibreglass Race nose cone with no headlamp opening I could buy to play with before cutting mine up?
I know Ricambi make a race nose cone, and it's cheap: https://www.ricambiweiss.com/en/ver...-front-fairing-ducati-400-600-750-900-ss.html But I'd rather cut up a used one.
