LFRPerformance Posted March 13, 2021 Report Share Posted March 13, 2021 Replaced the basket and cushions with a Redline Billet, Brand new EBC Plates and Fibers, New HD springs. Running Matoon Lockup & Cover. I am going to order a new inner hub and pressure plate and thrust washers. Clutch was together correctly per Yamaha diagrams and manual, plate springs torqued to 7ft lbs, thrust washers in correct place, rod and ball new. Clutch slips no matter how I align the pressure plate or adjust e pancake bearing and cable, am I on the right track? Lol Quote Link to comment Share on other sites More sharing options...
Keno Posted March 13, 2021 Report Share Posted March 13, 2021 Can you post some pictures of the assembly?Take the ring cushions out, part 17. Do not use them. Clutch slipping just at high RPM?Post motor mods, how much weight on the lockup.Is there slack at the clutch lever? Quote Link to comment Share on other sites More sharing options...

Post motor mods, clutch springs, how much weight on the lockup. Clutch is slipping as if it has a burnt clutch, won’t pull itself and acts as if clutch isn’t engaged. No ride on clutch just assembly and test. Seems to me that the clutch pack isn’t holding pressure, when completely assembled I can jack up rear end, put it in gear and roll the tires and watch the pressure plate slip against the fiber. Hub and pressure plate have slight grooving on the face at which the fiber rides against, which leads me to thing the two do not hold enough pressure between the clutch pack.

Keno Posted March 13, 2021 Report Share Posted March 13, 2021 The inner hub is trash, but you already knew that. It shouldn't prevent the clutch from engaging though. The pressure plate only seats all the way in every other hole. The pressure plate will sit away from the clutch pack of rotated 60 degrees, then if rotated 60 degrees again will sit flush againt the clutch pack.

seansy007 Posted March 13, 2021 Report Share Posted March 13, 2021 when all assembled do you have play on the actuator arm or is it tight all the way? Quote Link to comment Share on other sites More sharing options...
Keno Posted March 13, 2021 Report Share Posted March 13, 2021 Brand new clutch kit? And you have 7 frictions and 6 steels? With the pressure plate on, do any of the frictions wiggle? I'm starting to think there is a ridge preventing the pack from compressing all the way. Quote Link to comment Share on other sites More sharing options...

I'm starting to think there is a ridge preventing the pack from compressing all the way.Leaning towards the same conclusion, that the steeles are getting hung on the inner hub and not compressing the clutch pack fully, I can move the frictions but it does take quite a lot of effort. From all my digging I just seem to believe the clutch pack just isn’t compressing fully, and yes all new fibers and plates 6&7.

Oh, good point. There would still be friction on the other parts. Disconnect your clutch cable, and rechech the pancake adjuster Quote Link to comment Share on other sites More sharing options...

Disconnect your clutch cable, and rechech the pancake adjuster thats what im thinking it has to be something with the pressure plate not seating correctly either because the pancake and rod arent set right or the plate isnt slotting into the hub 1 Quote Link to comment Share on other sites More sharing options...

Lol i have yet to assemble my clutch with the pancake and everything but I'm pretty sure when putting in the pancake you do not include the ball in the assembly just the rod and pancake. correct?
