Clutch Springs

I wouldn't dare because I'm rougher on a clutch than most, but that would probably still be better than EBC or Vesrah's "HD" set of springs. I'd just have to wonder about different pressures around the plates though, like if it would let it somehow flex against the three weaker springs and not hold the plates all level? I couldn't answer that.

Well this comes from working on XS650s, clutch starts to slip under load, 3 alternated Barnett springs solves the slippage, so 1 stock then 1 Barnett and 1 stock etc.. Should I put in all six or give this 3X3 a shot ?

Depends how much your time is worth. If it doesnt fix it you'll be going back in to add 3 more. If you use all 6 now your left forearm will eventually get bigger and match your right and your buddies will then only be able to pick on you about your harry palm.

In all reality, after I put my 6 Barnett HD springs in it only took a week or so to get acclimated to the additional force and has never been an issue. No fatigue from stop and go traffic either.

I have roller bearings that can be installed to the clutch lever and if you like, the front brake lever too. The levers need to be drilled out to allow room for the bearings to be installed.
I'm going to put all 6 Barnett springs in as the 11 has much reduced clutch pull than the XS650, we shall see soon.
Thank You ! Done };~)

I think you're making the best choice. The only time the stiffer clutch handle has been an issue for me was the last two years going to XS Southeast, I-40 traffic jams moved along at a slower than walk pace. So idle speed with the clutch out was too fast, but it wasn't stopped either. That being said, after an hour of feathering the clutch handle, it'd be an issue with even stock springs.

Barnett springs are in, now for the cover. Can't seem to figure how it actuates the clutch release ?
I had a time back in 76 on a 75 RD350, stuck in traffic for about 10 mi. on I 94 coming back from Eleva, Wi. to Milwaukee about 240 mi.. Traffic came to a stand still then moved so slow I turned the bike off and just footed it, hours. Then traffic started moving and around the corner motorcycle parts all over in the grass, turned over trailer and a truck, I saw a yellow tank in the grass with Norton logo. Stopped at the next rest and there were 20-30 HDs parked there, went to the far end away from the HDs, got off started walking around and here comes 3 big HD guys looking the part. They came right up to me, I stood my ground, they asked did you see a trailer full of old vintage bikes, yes I said but I hate to tell you they are scattered in parts all over the freeway. They said thanks and sent some of the group to go check it out. I split as fast as an RD350 can go, home !!!!!

Hey Done,

Okay, these aren't all of the photos I have, but they are all that I have on Photobucket right now, and I'm at my laptop, not my desktop where I have others I could upload, but oh well, here goes.

First, start with the actual clutch bucket...the frictions have tabs that engage the bucket. The Steels have teeth that engage the clutch boss. The 6 shafts are attached to the 2nd pressure plate at the bottom of the bucket, the boss and #1 pressure plate goes into the plate stack, and the star plate/throwout bearing is bolted to the #2 pressure plate with the springs in between. The #2 bottom pressure plate is squeezed against the plate stack by the Springs and the Star Plate against the clutch boss/#1 pressure plate.

Now look at these photos. Below first is the throwout rod/pin and round housing that fits against/into the Star Plate/throwout bearing.



Below just shows the 3 large bearings/and slotted/ramped clutch case housing, and the backside of the throwout plate/pin that also has ramped slots. When you pull the clutch lever, it rotates this throwout plate/pin assembly which makes the pin push inwards towards the star plate/throwout bearing as it rides up/out of the slanted slots on the 3 BEARINGS.



Below just shows this throwout plate/pin and how it fits into the star plate.



When this pin/plate pushes against the star plate it depresses the star plate evenly, which compresses the springs and separates the #2 pressure plate away from the plate stack and the #1 pressure plate of the clutch boss. This allows the frictions spinning in the bucket to slide past the steels also spinning in the bucket but attached to the clutch boss which is attached to the primary shaft.

When you release the clutch lever, then the #2 pressure plate is allowed to squeeze the plate stack against the #1 pressure plate/clutch boss and so the engine spinning the bucket can then spin the clutch boss which then spins the primary clutch shaft which then spins the shafts in the transmission and sends the power to the middle drive and rear wheel! Phew...hope this helps your understanding of how the XS11 clutch works!

Thanks T.C. !!!!!
Still don't get how the springs pull the top and bottom plates together as they seem to push them apart, and the bolts seem to pull them together ?
But put it all back together ( had to the adjust the actuator for the thicker XS650 friction plates ).
Rode around the hood and shifts so nice, just snicks into gear ( all 5 ) but I did not exceed 35 mph.. Getting cold here but they say a warm up is coming, ( 40s-50s ). Carbs need sync, valves need checking. a few more parts are getting painted. I'll try and get a video of before or after the tune. Cost more than expected. Thank You Andreas for all the parts needed !!!!! And thank you all for your input !!!!!
