Ballacraine Posted May 17, 2005 Author Share Posted May 17, 2005 The difference is important and thanks to lower inertia, accelerations are much better, especially at low rev. 51967[/snapback] That is one of the characteristics I really like.

al_roethlisberger Posted May 17, 2005 Share Posted May 17, 2005 Conversely, the additional mass of the DP unit smooths out idle and steadies the revs.... a trade-off. After all, flywheels do serve a purpose But I suspect the tradeoff, while probably noticeable either way, is not huge anymore between the SP and DP versions. al Link to comment Share on other sites More sharing options...

I suspect you are quite correct, Al. There is quite a price differential between the single plate unit & the dual plate. The dual plate is considerably more expensive. I do not want to lay out on it & wish I hadn't, if you follow me? Nige. Link to comment Share on other sites More sharing options...

Baldini Posted May 17, 2005 Share Posted May 17, 2005 ....It would appear that they have quietly redesigned the profile of the flywheel. It seems to be more substantial around the boss area.... Ballacraine, What knowledge do you have of this? Have you seen both types? I heard the same, but don't know it for fact. KB Link to comment Share on other sites More sharing options...

KB 52034[/snapback] It was on a thread on this board somewhere. Some kind soul posted a comparative pair of pics showing the old and revised design. I'll see if I can find it, but don't hold your breath. Nige. Link to comment Share on other sites More sharing options...
Ballacraine Posted May 18, 2005 Author Share Posted May 18, 2005 The DP is more expensive? That's interesting. al 52024[/snapback] Considerably so. Nearly double from some sources. Nige. Link to comment Share on other sites More sharing options...
jrt Posted May 18, 2005 Share Posted May 18, 2005 close to double sounds right if I read your discussion correctly: comparing a standard (mostly Tonti parts...) dp clutch to sp clutch: $66 for one plate (need 2) $40 for intermediate plate $95 for input hub $1.25 for one spring (need 8) flywheel lightening services are $275 for the cheapest I found in 5 minutes, but you have to provide a flywheel. I couldn't find the cost of a flywheel or ring gear. RAM clutch: $500 even if you HAVE a flywheel/ringear, then all the rest is still $550. bottom line- it's expensive to change the style of clutch that you have.

Mike Stewart Posted May 19, 2005 Share Posted May 19, 2005 Ok, Are the Ram clutch setup low inertia because it has a single disc and or because of the aluminum flywheel? How much lighter are we talking compared to the V11 S which already has a lighter flywheel than the early spine framed bikes and Tonti framed bikes. Also, I like the fact that the assembly has been balanced which would most likely be better than the Guzzi way. http://www.mgcycle.com/clutch.html Mike Link to comment Share on other sites More sharing options...

(Pete Roper has my old one and may confirm). The replacement Ram was approx 1.5kg. Spins up a fair bit quicker. 6000 kms with the new one and no problems so far !!!!!!!!!!

Obviously it is a different design. Did you get the chance to do a visual comparison before the new unit went in? Is the new one strengthened around the boss area? TIA Nige.

The spare parts guy told me it was about 1.5kg. I weighed the old one later to compare. I'll see if i can find the paperwork as it did have photos of the unit.

jrt Posted May 19, 2005 Share Posted May 19, 2005 1.5 kg sounds awfully light. I put a RAM clutch into my Eldorado and it weighed in at 10 pounds (~4.5 kg). That includes everything, including the transmission input spline. FWIW, the Eldorado stock clutch assembly weighed 26 pounds (12 kg). Unfortunately, I don't know the weight of the 'new' sport clutch assemblies, but it is waaay lighter than 26 lbs Link to comment Share on other sites More sharing options...
Guest rosso mandello Posted May 19, 2005 Share Posted May 19, 2005 Has anyone experienced a Clutch, that does not rattle, my ROSSO MANDELLO sounds awfull, but the function of it is OK. I hope it exists Link to comment Share on other sites More sharing options...
Guest ratchethack Posted May 19, 2005 Share Posted May 19, 2005 No. Dry clutches rattle. Think of it as another instrument in the percussion section of the grand orchestra of Guzzi music. Link to comment Share on other sites More sharing options...
