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

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....

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.
