You kow it makes sense..............

You know that if you don't check, you'll never trust your bike again..........
certainly not enough to ride up to one of Pompey's meets

Okey Dokey, the clutch............
It seems to me that every SB6 I've had as let me down with the clutch, I'm now thinking that this is coincidence. It appears that every one has been affected with a different problem but all manifest the same result...clutch drag.
With this particular clutch I decided I was going to solve the problem permanently so started by taking plenty of "before" measurements to compare with the "After" measurements........


Free play on the pressure plate amounted to almost 2.5mm but that shouldn't cause a problem as the slave cylinder would automatically take that up.


Perhaps theres too much deflection at the slave cylinder causing too little movement on the push rod......No, deflection is less than 0.01mm.

Measure the movement when the lever is pulled in then....1.2mm doesn't seem enough

perhaps the push rod has worn.... No, still 108.5mm as it should be.

Out with the 50mm socket and air gun then and let's get inside the sucker........
It's nice when you find the problem staring you in the face and no longer need to scratch your head and your arse whilst puzzling of Suzuki Sans and Bimota designs...........
Seems some little monkey has been here before me(as they had on my previous clutch project) and replaced the clutch plates


Stripped down awaiting parts.......


This is some of the lumpy crud that came out with the plates. I presume that these lumps were wedged between the plates causing the drag. Also, cheap after market plates were used and the WP/WR set up was used(seems it always is with clutch replacement on these) as opposed to WS, WT, WV set up



Finally........
here's the reason you shouldn't use cheap after market plates in these big motors children. Bear in mind SWMBO was using this bike most week ends right up until the big bore was on the road. She complained about the dragging clutch from time to time and I explained that she needed to learn to "ride around" these small problems



This was going to be a downward spiral, as one lump fell off and got stuck between the plates, causing drag and heat, it was going to cause others to fall off and cause more drag and heat.
Looks like the sumps gotta come off when I can get at it. Deja vu.

In the WP/WR engine there are two different type of friction plates but in the WS> engines Suzuki San modified the set up and used three different types of friction plates. Just about all after market plate sets use the 2 plate system. Go figure.

New plates ordered so the engine should be back together soon(when I get an answer on this coolant pipe) and then onward and upward

Nice clutch.....

What have you been doing to that poor bike

The warmest November in 60 years and your moning about your cold garage. Wus

Thanks for offering evilchuck and Cbar, thanks for answering the question.

Now, where are the big drills.

PS......for the Bimota factory........If your not sure what a big drill is, just ask and I'll post a picture for you

[Evilchicken0]

Bimota should check the parts when they come in and before they're fitted.
Maybe it's a V-Due moment

Inspired by this string,all the beautifully painted brackets,clean engines etc,
I decided to start my own strip down/rebuild.

Dont know wether to thank or blame you, if I find any horror stories, will post them.

7 hours later, down to engine,frame and electrics.

7 hours

take your time, don't hurry Takes about 3 hours to take every nut and bolt apart but then again, I've done it quite a few times before.

I'm glad that this thread has had an effect on you Martin, good or bad. I was contemplating not bothering posting the rest of the re-build due to the poor response but if it's going to help you, I'll carry on posting
If you need help with anything, shout up.

PS....start your own re-build thread Martin, We can't have too many pictures of Bimota's in bit's (or post your re-build pictures in my thread) as it's probably the best Bimota reference place on the net

Absolutely agree,I am not a mechanic ( electrician to trade ) but my job
and my "hobby" make it all a learning experience. Seeing photos and reading
details of Bimota quirks help me to tackle what at first looks a mechanics
nightmare, unless they have really small hands, and three of them at that !!!

Keep up the stellar work, we do read, although sometimes not reply
