Desmonto (sp?) engines

[idb]

what a waste... send them to me, I'll give them a good home!!!

One each eh Blakamin?
Which one do you fancy or should we have a toss off?
now....I'm sure that doesn't sound quite right but I can't put my finger on it......

So why do Ducati engines need to have cam belts replaced at such low mileage. They should be easier on belts than spring operated valves.

toss off?

Where I come from that phrase means something totally different to what I think you mean! <<< the phrase, not you!

I'm from the provinces - we do things differently out here (hillbilly smily)

[TLDV8]

Desmodromic also allows aggressive opening and closing values with no chance of valve collision on overlap...the hairclip springs aid sealing at cranking RPM,you can run without them but it can have an effect on harmonics with a street engine (imo)

Vee Two SD905 13.7/1 CR .. 41 FCR's etc etc .... still making HP at 9300rpm went 20000kms without needing a valve adjustment.



TL1000 cam on the right

That TL cam actually looks harsher than the Duc.
My understanding is that modern spring technology has virtually taken away any advantage that desmo had - certainly as far as street machines are concerned.
Let's face it, it's largely a marketing tool now. Much like Guzzi's transverse V or Harley's tassels.

sounds good... without the toss.... we'll just decide somehow....


The TL has to look like that coz a spring closes it.....

The ramp looks steeper on the Ducati cam. Generally I think ducati desmos do open the valves quicker which gives them that exhaust note. TLs always sound 'soft' to me.

All that metal flying around. Pneumatics such as the F1 cars use should be better - the perfect spring that weights nothing, has no harmonics, and the spring rate could be adjusted on the fly if required

And they were also playing with electromagnetic valve actuation as well,but so far no one has managed to make it work
