Must be one powerful 916 to pull 15/38 at Donington and 15/36 at Silverstone, mine just about gets away with 15/38 at Thruxton |
I understand the gesture to offer gearing advice to a fellow Ducati owner based on your own experience, but some of you are missing an important point. Different Ducati models have different different red-lines, primary drive ratios and different transmissions. So they require different sprockets. First, 916’s and 996’s both have the same standard-ratio transmission, but the 916 has a 2:1 primary drive ratio where the 996 has a 1.84:1 ratio. So the answer to the initial question about the best gearing will be different for the 916 and the 996. Which model is it? Second, (if his profile is correct) dave w drives a 999 that has a 1.84 primary drive ratio and a close-ratio transmission, which is a set-up that has a different overall gearing and gear spacing than either the 916 or the 996 in question. So a positive result with a particular sprocket combination on a 999 doesn’t translate to a model other than a 998. If you convert his 999 recommendations to a 916 set-up then the recommendation become 15/37 to 15/42. For the very highly geared 996, the closest you can get is with 15/42 to 14/42, but I strongly suggest that you not use 14-tooth sprockets on 99s’s, 998’s or 999’s because of higher chain tension. |
Can someone PLEASE post a tricky question to test our self-appointed panelists? I'm gonna resent awarding the prize for a half-arsed contest. Doesn't anyone have a really tricky techncial question to ask? :puzzled::puzzled::puzzled::puzzled::puzzled::puzz led::puzzled: |
My question before logoff Why is it that Ducati still insist on producing red and yellow bikes when we all know that Blooo is a much better colour? And Ruthie Babe, I'll open the box please what ever the prize rgds mort |
ok - in for a penny...and its one I'd wondered about for the desmo boys as well.. I have my 93 900ss turning quite nicely after dropping the forks though the yokes some 20mm (serious I know but, I had to do this to be able to fabricate my own hi-rise bar kit) and fitting a Magnesium Marchesini front... But....for the track wouldn't a combination of mild head dropping AND raising the rear ride height be better. Finally - does anyone actually make a proper rear ride hight lifter/adjuster (eg - BLOCK OF METAL) seperately, to do the job - I have not found any yet. If my feeble memory still serves me only Ohlins shox actually have real height adjustment built-in? Ahem - I thank you all in advance.... Frazzeled Franko [Edited on 5-2-2005 by Iconic944ss] |
Not technical questions but ones I keep asking myself Why did Ducati replace the 998 with a 999. Why did Emmett and Chilli both struggle so much with the 999. How many miles should I expect my 916 to go on for considering the constant abuse it gets. Why would somebody want to paint a Ducati BLUE :frog: |
ok heres one-- is it possible to fit 600ss crank barrels and heads to 750ss bottom end(gearbox/crankcases) this will enable a six speed gearbox and the use of an oil cooler/oil temp guage would it not?or is it possible to fit oil cooler and-oil temp guage to 600SS crankcase/gearbox and then fit ducati performance aftermarket six speed gear cluster?-- just thinkin of next years project |
I thank you boys. Keep it coming, Iconic, Skidywids and Monstermob. Especially Skidywids as you are actually a panellist. :bouncy::bouncy::bouncy::bouncy::bouncy: |
Frank your memory still works the Ohlins shock for the SS range (DU235 I think) does have a ride height adjuster built in so that you can increase the rear rideheight by making the shock longer than the standard 328mm. I am currenty working on a solution to jacking up the back end of my desmo Due 600SS, an couple of hours ago I picked up Senna3's spare shock to take measurements and have also measured a couple of shocks I have, I now have a little drawing of a block that should fit in between the swing arm and a suitable shock. Currently working around a Paioli shock off a Laverda, it has a ride height adjuster built in and if I get things right I should be able to vary the over all length from the standard 328mm up to around 340mm. i did think about popping into work this evening and knocking out a prototype. The Paioli shock has about 12mm of adjustment and at its shortest is 280mm, giving me 48mm between fixing centres for my rideheight adapter |
For anyone interested in how it's done... The 900ss Ohlins units are adjusted by winding out the bottom mount point. There's 2 options for the 900ss according to ohlins catalogue... the DU235 (as skidywids says cos he da man!), or a DU245 which has a remote preload adjustment. Adjustment range on the Ohlins is also about 12mm. ![]() |
