Duc peoples..a belt question

[backMARKr]

Thanks Gino.  Hey, whats your take on that DS? I have been thinking about retiring the aging 996, and going that route. I hear the reliability is better, and I can run more classes, but I also hear it is a beast to get the suspension dialed in.... thoughts?

Cheers,
Chris

Chris...I have a plan for you......


(1) get in car
(2) drive to Ben's
(3) buy SV Superbike (pretty sure he still has one of Hernan's sitting over there)
(4) ride bike for two to three seasons in the 3-5 classes its legal for each weekend
(5) No more EYEtalian bike problems
(6) Check the "unique" box, in that the only thing "normal" is the frame --- the rest of the thing sure isn't run of the mill

damn Gino your right on top of this thread lol.  i've been thinking about a 749r as an up grade from my 748r  would be the ticket in Tbike and f40 if your that old . they have all the good stuff from the start and there fairly reasonable. sneak in some big slugs and ride the middleweight classes

Chris,

I have a 996 track bike as well, and love it. Problem is it's not competitive anymore.

The 1000DS is a great racebike, very reliable, handles well and not many bikes are faster for the LW classes, unless you are going to drop $30K on a Bimota.....

I kept mine stock so I could race LW SuperSport, I put slip ons, GP chain and sprockets, STM breather (requires some kind of custom breather box or your airbox will get coated with oil), a K&N air filter and made 92 HP on the dyno with the airbox opened up. With the stock (SS legal) airbox cover, it's more like 88HP.

I raced on stock suspension for years, all I did was raise the rear to the max (if not the stock exhaust collector or pipe will drag). As I got faster, I had the shock and forks re-sprung at GMD, and added the longer end to the stock Ohlins shock to raise the whole bike.

All I have done in 5500 race miles (6 years) is 4 valve adjustments, 3 or 4 sets of belts, and one exhaust valve guide. I added a power commander a few seasons ago, it smooths out the powerband a bit.

Handling wise it's no 996, the chassis flexes more and it requires some more effort, but mine has never been crashed and handles very well. Fast enough to win at Daytona!

If you decide to go the 1000DS route, let me know, I can give you my geometry measurements so you can have a good baseline setup to start with.

The shop I work with, Moto Corse Performance, has put together about 20 of the things, and a bunch of 800's too, so I've benefited from all the tricks. You can go crazy with these bikes and easily get 100+HP, but I always figured there  was more time to be made by improving my riding so I left well enough alone.

Others on the board recommend alot more maintenance than I have done, but my experience has been that it's just not necessary. I can only give you my experience which has been very positive.

SV's can be made to perform pretty well too, and I've heard they handle just as well. My brother had a pretty well prepared supebike SV and I prefer my bike. Faster and well, it's a DUC after all!

I would love to campaign a 748 or 749, but they are really only good for one class, Thunderbike and LW F40 so I prefer the 1000, I can ride in 5 classes and be pretty competitive in all of them. My SS legal motor makes it tough to compete with the fully prepared superbikes and such, but a better rider could keep up....

I'm with you Mark, sounds like a cool idea. But I wonder how much better it is than the 748R? And the 748/996 is just the coolest looking Duc IMHO of course....

Me I'm going to hang on to my 996 until it's legal for MW or 748 is legal for all the LW classes, then I'll hunt down a 748R motor. I just love that chassis I guess.

Then again I rode Chris' 1098R, that's no slouch either.....

[Ducmarc]

i think the 749r motor in my chassis would be the ticket  but as much HP Chris gets out of his I'm not sure it's Worth it. i can't out ride it now anyway plus it's paid for sometimes though you want something new, then  the boss brings me back to  earth

Hey Gino,

How did you have you SS set up?  Are the fork flush or dropped in the triples?  Is the shock length fully extended?  I have heard different setup stories where some people knife them out and some people raise the whole bike.  What's your preferred setup?

I'm with you Gino, I like the look of the 748/996. And yeah Marc's 748 is one fast bike producing some 120hp as tested at MotoCorse. I must say that it is as quick as that fast Bimota and the last I raced it at Homestead it gave that rider some fits of anxiety with that much power. Sadly I did not have the skill to unlock all it's potential.

Chris has told me that he gets some 130+hp out of his RS and I believe it. I think the 996 is a great ride and with some performance mods could give the competition something to think about.

My 800 was set-up using the measurements taken from Gino's bike. What I have is essentially the 1000 adjustable forks and Ohlins rear shock with the shorter extension. The forks are set in the sotkc location with the clip-ons above the triple and pretty much flush. I can take more measurements if needed. The rear shock length measrues around 13 3/4"  from eye to eye with the weight of the bike on it without bodywork. I hope that gets you in the ballpark.

For me switching to the Marchesini aluminum wheels  translated in a big difference in turn in and just seems a lot better overall. With the stock 800 wheels I had trouble getting the bike leaned over onto it's side and thereby missing my desired turn-in. There are many that raise the whole bike or raise the rear but I find this geometry desirable. I did notice that with the ohlins shock the rear was taller by about one inch over the stock Sachs 800 shock.

read my lips, monster triple clamps  and mr boy's makes over 140

[majicMARKer]

I'm only going by what he tells me. Well I have some changes that I am making to the 800 trying to get into a more comfortable position on the bike. I don't know if I need the monster clamps because the handling is great.
