As I have searched, I have had some mixed results on Syn oil, but that's not what I want to get into to.

This is my experience... I bought the bike with 17,600 on her and the clutch did not slip, BUT it did seem to catch early with a really long friction zone... i.e. I let the clutch out about 1'' and the engine would start to bog a tad and the bike would move but I could freely rev the bike. I would not be fully engauged until almost the last part of the clutch throw was fully released.

I figured grooves in the basket maybe giving me a bit of fuss.

I read that it may be the spring plate under the paino wire in the drum could be the culprit.

I decided to switch to Rotella 5 40 in the blue jug. Clutch operation seemed better after a few rides, wasn't grabbing as early and engauged smoother. Well a few weeks ago she decided to slip on a second gear blast and I thought well maybe in the excitement I rode the clutch. So I made sure to be completely off of the clutch and went WOT only to find more slip so I let off right away. I went home and checked the free play in the lever, cable operates very smooth, so I figured chaulk it up to running syn in an old clutch and/or weak springs. But wait, there is a rattle as well.

Findings

Hub nut was a tad loose, but when I bent the safety washer straight I could no longer turn the hub nut? Was I imagining that I could turn the hub nut because I sure as heck couldn't get it to move after straightening the washer and had to get a big wrench out of the tool box.

Measurements

Sping free height 38.85mm across the board

These will be replaced with Suzuki OEM springs, bolts, inner spring guides

I measured an average of 1.97mm on the steels... aren't blue, warped and look brand new with the perforated holes in them

drive plate (frictions)

I measure 2.97-2.95mm on them as well.

I have no intentions of replacing the steels, figured a good cleaning and scuffing would bring them to reusable condition

The drum does have the three big springs a tad loose in the back. I am sure some will say that I could get away with it and some would say to send it of to one of the two reputable guys and another would say order Suzi OEM which is what I plan to do. The drum has ever-so-slight markes in the splines that you can barely feel with your finger but they are there. I understand that Suzi has supposedly made an update to their drums according to Falicon (read from a post on here)

I have also read that Suzi has revised frictions and APE still has the old style although it was a bit nebulous as to which style is the better style.

Some would say that because the hub nut was loose to get a hub... I am still wondering if I was imagining that darn thing being loose or if it was the washer that moved, but here is another debated topic.

Suzi oem nut, used by many for many years, replace it as you take it off along with the washer VS. datada DAAAA APE's manly hub nut in which you could take out Superman with it and then reinstall it back on the ol GS.

I definitely can NOT say that money is no objection...wish it was. More like biting the bullet.

I was thinking new frictions 12.78 each x 9 for a 115.02 total
For all new springs, bolts, washers and spacer 6.4 x 6 for another 38.40

Which would be order number one to qualify me for free shipping.

Next month grab the :edited: (I meant to say basket) for 174.33
Nut and washer ___ to go APE or not

And a clutch release bearing... But wait there's more

Bike needs tires... expensive
Fork seals cheap
Gotta check the shims hopefully won't need too many

Borrowed time components

Stator
regulator
coils
____________

not cheap ^^^^


Any thoughts or opions are welcome.

I did think about just replacing the clutch springs for now and order up new parts for it over the summer and do the rest next winter, but if she still slips, I suppose I could go to non energy label castrol GTX 10-40 as my dad has never had any problems with his bike and that's all his bike has ever used. I'm just the person that knows either you pay now or pay later.

If money is that critical, just get a gasket, don't worry about the shipping costs. Place a washer behind each spring as a shim to add just a bit of pressure.

Bike needs tires... expensive Look at the Cheng Shin Hi-Max from Tires Unlimited. Decent tires, long-lasting, good grip. Most expensive front tire is $55, most expensive rear is $65.

Fork seals cheap
Gotta check the shims hopefully won't need too many Shims are available from Z1 Enterprises for under $5 each. Send me an e-mail (click on my name for address) and I will send you a copy of my valve adjust spreadsheet to help inventory your shims and determine which one to use.

This is a bunch of words to make the system think I have typed something here.
 
Doubt all of this trouble was caused by oil. I have run; Royal Purple syn,(ok) Amsoil syn, (very good) Honda GN4 dino,(good) and Honda HP4(way pricey).

These were all run at different times, but with the original stock clutch.
I have an '80 GS1000G 40K mi. lightly modded which I ride very hard. I haven't had any slippage issues. Though I have heard that certain aftermarket fibers may work better specificaly w/dino or syn depending on if they were organic or kevlar.
 
You have to be careful adding shims under the clutch springs since it can cause the springs to coil bind. Check first to make sure there is clearance before adding springs.
 
Man, are you overthinking this...

Put the bike on the kickstand and replace the clutch springs and clutch cover gasket. (No need to drain the oil, since it's out of the way when the bike is tilted to the left.)

This takes about 15 minutes, and there's about a 99% chance new OEM springs are all you need to eliminate the slip.

Use whatever oil you want -- synthetic doesn't make clutches slip.
 
Springs will fix it usually.
If not, do it again, it takes less time than it took you to type your first post.
 
heheh maybe even faster than it took tKent to post his post two times...lol
 
The spec for the fibers is 2.9-3.1mm and I measured 2.95 to 2.97 on mine. Basically means I have .05-.07mm of additional material on the fibers.

I would go with new springs, bolts, guides so as to not worry about coil bind or old bolt failure... I can afford these items.... Christmas funds will allow \\:D/

The fibers were on the low end, but maybe I am over concerning myself? I ride about 1G-2G miles a year, and while the quick blast is had once in a blue moon I don't forsee any drag strip time in the near future.


I figured the oil probably didn't have squat to do with it other than expose weak springs.
 
Criss cross the steels with 220 wet-sandpaper. Those fibers should go another couple of years. Put in new springs even though they are in spec. (38mm?)
Make sure you have play in the clutch lever when cold and down right slop when warm.
 
I just wanted to follow up:

New OEM springs, double stacked washers, criss crossed steels with 220 and reassembled.


Used NEW OEM hub nut and washer


NO SLIPPAGE.
