SBBXX Posted October 23, 2004 Share Posted October 23, 2004 I’ve got a 97. I’ve been noticing the clutch slipping for a while. I changed my oil and it was better, but with less than 3000 km after the oil change, (Mobile 1), it’s gotten really bad. What would you do? Replace the plates? Replace the whole clutch? Is there a better aftermarket one I should be looking at? Would a post 99 clutch fit, and if so, would that be a good idea? and How easy is it to do myself? Finally, could it be something else? Thanks marty Quote Link to comment Share on other sites More sharing options...
Northman Posted October 23, 2004 Share Posted October 23, 2004 Really only a couple of things to check, Marty. Bleed & flush the clutch fluid, first. Pull the slave cover, and remove the clutch pushrod. Make sure it isn't hanging up, not allowing the clutch to fully engage. Other than that, sounds like you need clutch plates. I'd replace both steels & fibers, and go with stock. Replace the springs while you're at it for insurance. Why don't you PM me directions to your place? I'm leaving here in a few minutes with no destination in mind, so may head that direction :idea: Quote Link to comment Share on other sites More sharing options...
Northman Posted October 23, 2004 Share Posted October 23, 2004 Oh, not sure if the post 99 will fit or not. I imagine it would, as long as you're replacing the basket as well. Clutch replacement is easy. We could do it in less than an hour, if you needed assistance. Quote Link to comment Share on other sites More sharing options...
Northman Posted October 24, 2004 Share Posted October 24, 2004 97/98 clutches are very different from 99 and up. Nothing interchangeable at all. I thought the difference was in the basket. Could you not swap it out completely? (basket, plates, pressure plate, etc.) Any idea what the difference is, Dean? Splines? Quote Link to comment Share on other sites More sharing options...
Northman Posted October 24, 2004 Share Posted October 24, 2004 OK, so as long as he's using the basket and all pieces from the FI setup, it'll work. Thanks :grin: Quote Link to comment Share on other sites More sharing options...
Red J Posted October 24, 2004 Share Posted October 24, 2004 If all you need is a set of stock clutch plates, and want to futz around with it, I have a set from Paully's motor. Look fine, I haven't measured them. '97 XX. J. Quote Link to comment Share on other sites More sharing options...
Pete in PA Posted October 24, 2004 Share Posted October 24, 2004 This is the first clutch I've heard going out on the XX. On my Sabre I put in a Barnett at 25K miles. It's still in at 100K miles. I replaced the fibre and steel discs. I thought the 99 and newer dropped 2 discs and changed the friction material and leverage of the master cylinder.

Northman Posted October 24, 2004 Share Posted October 24, 2004 I thought the 99 and newer dropped 2 discs and changed the friction material and leverage of the master cylinder. 99-up uses 7 friction plates, and 6 springs in the pressure plate. 97-98 used 5 springs, and not sure how many plates. Leverage of the master remains the same, IIRC, as the master itself, and the slave are the same parts. Quote Link to comment Share on other sites More sharing options...

Northman Posted October 24, 2004 Share Posted October 24, 2004 9 is what I thought as well. Ron Ayers and Partsfish don't tell you how many plates you need, just the price & part #. :???: Quote Link to comment Share on other sites More sharing options...
Pete in PA Posted October 24, 2004 Share Posted October 24, 2004 You made me look it up. :roll: According to my manual, 9 plates in the clutch. According to my 99 Rider mag, "a newly developed clutch friction material, plus changes in the clutch ratio and master cylinder, allowed the number of plates to be reduced from nine to seven, which results in a 15% reduction in clutch effort." I personally would leave it at 97 spec. and just replace the plates with factory or Barnett stuff. Also check the springs for free length.

Pete in PA Posted October 24, 2004 Share Posted October 24, 2004 BTW Marty, how many miles on the bike, did you buy it used, clutch abused? Just wondering why it's out. Why the big desire to update to 99 spec.??? Quote Link to comment Share on other sites More sharing options...
Northman Posted October 24, 2004 Share Posted October 24, 2004 Confirmed with Ayers. Master cylinder & slave are the same throughout the years. The new clutch has less plates, but more clamping force (6 springs vs. 5). IMO, using the newer clutch will not be a problem, but not a necessity.

Red J Posted October 24, 2004 Share Posted October 24, 2004 I would not use Barnett over the Honda OEM. Not that I have any specific experience that says Barnett is bad, but that Mr. Stotz says he has tried about everything over the years on an XX and found that stock was just plain best.The list of things that aren't stock in his motor is very short. Rods, pistons, valves (head flowed/ported with 1mm larger exhaust valves), multi-stange lock-up. His tranny is back-cut but still the stock one. Crank?

blackhawkxx Posted October 25, 2004 Share Posted October 25, 2004 Most of the people at the track tell me that on mostly stock Hondas, the factory clutch is the best. The after market ones grab and don't let you slide it out of the hole. Quote Link to comment Share on other sites More sharing options...
