I changed the oil over the weekend, went with synthetic Liqui Moly, will keep an eye on the level.

Using an oil with a high Moly concentration will CAUSE the clutch to slip. Can can only assume that it has a high concentration given it's name. You need to use a motorcycle oil that is formulated specifically for wet clutches or Shell Rotella which has proven to be safe for wet clutches.

When you did your oil change, did you inspect the oil for clutch plate friction material? Did it look almost silver or like someone added sparkles?

Liqui Moly is the brand, its synthetic motorcycle oil. The clutch started slipping with mineral Suzuki oil in it.

I dont know if I saw any sparkles, but the oil was pretty dark, considering that I added over a quart and replaced it almost immediately after. I still have the oil in the drain pain, I'll shake it up and get a sample for a closer look, but either way my clutch is toast.

I am in US, NYC. Liqui Moly is a German oil company, they make a lot of different oils, not just motorcycle oils.

I'm not in a cult, I'm experimenting. Last oil change I did was at 5k with Suzuki mineral oil, and by 6k I got clutch slippage and was down over a quart. I am still trying to wrap my head around what the hell happened, the bike does not leak and does not seem to burn any oil.

Reply #50 - 05/01/23 at 20:07:50 Either way, looks like I'll be doing the clutch on the bike in the near future, i see there is Barnett kit on Amazon. I heard they are better than OEM? https://www.amazon.com/Barnett-Complete-Clutch-Suzuki-Savage/dp/B07YCVNZ2C

Can you guys recommend the clutch kit I should go with? There is the OEM part number LS650CLKIT2 - it has all the springs, clutch plates, and even a new gasket. There is also a barnett kit, EBC kit, and a bunch of very cheap ebay kits.

I read that barnett doesn't last as long as OEM?

There was also a thread saying there are different legths OEM rods, and a longer rod work better?

I have no problem getting the OEM, its not that expensive, its just a little concerning how my original clutch only lasted 6k miles. I really don't do anything that could potentially damage the clutch, other than once in a while cruising at close to top speed. I do generally run the bike pretty hard, but it shouldn't affect the clutch to the best of my understanding, as long as I am not letting it slip.

I read that Barnett springs are 13% stiffer than OEM, so I imagine if I was to use oem plates with Barnett springs, they should be locked together tighter and so there will be less chance for slippage and the clutch should last longer. What kind of adverse effects can I expect from stiffer springs?

And I am trying to get an understanding on the clutch rod - Suzuki sells three different size rods. What does the rod do, what are the benefits of a longer vs shorter rod?

slightly stiffer clutch lever, just lube the cable good and you won't notice it.

the 3 lengths accommodate clutch plate wear. choose the right one for the amount of wear.
Pick the one that sticks out of the spider about 12 to 12.5mm.
at 13mm, the clutch is pushed in and won't engage.
I imagine this varies a bit from engine to engine, but it's always worked for me.

I think I will go with the Barnett clutch over OEM, if it bites harder it should technically last me a longer time than OEM. Versy, I'll need to also get your tensioner while I'm at it, I'm just not ready to plunge on the clutch and the tensioner just yet.

Essentially you just weld on a piece of plate to it? I can probably do it myself, I have a tig welder, if you share the template.
