Wet Clutch Wear

I have removed the wet clutch from my 2011 700 in order to slug it. I noticed some shallow grooves in the drum and I am unsure if this is normal or not? I have never had a wet clutch out before or have seen a new one to compare it too. I am looking for some opinions on to whether or not I should replace the wet clutch before I reassemble everything? There is only 100 hrs and 728 miles on it. Does this look normal for something with this amount of hours and miles on it? Thank you in advance!

those look pretty deep...I'd say replace it . I don't think mine looked that bad whenever I done mine.

thats alot of wear....not normal for that many miles...what oil you run and what size tires

The tires are stock and I run Mobil 1 4T 10w40 for wet clutch. The motor is all stock and my clutching consists of gold spring, 18g greaseless weights, and a .040 shim between primary sheaves (will be machined sheave and OD weights once it comes in). I was surprised to see grooves with that low of miles too and thats why I came here to get confirmation to what I was thinking. I bought the unit new and broke it in on regular yamalube then switched over to amsoil 0w-40 atv oil which I was not impressed with (ran hotter and did not seem to shift as smooth). I have been running mobil 1 4T for a while now and have no complaints. What do you guys recommend or use for oil in stock units? I have ordered everything to replace the entire assembly including oil seals, gaskets, and oneway bearing. Hopefully I will have better luck with the new one! Thank you all for the help!

i run yama lube and my clutch looked new after 2000 miles with my big motor

yamalube..its designed for it. ill never switch. ill know how mine looks soon. hopefully as good ,as yours sounds james.

Looks like I will be going back to yamalube! Does anyone know what the diameter and length of the kms slugs are? Are the 660 and 700 slugs the same size? Thanks!

I was on Royal Purple,the wet clutch did not last. Replaced the wet clutch assembly added Yama-Lube 10w-40,the clutch holds tight now, I won't go back. My drum had lines in it I used some 40grit paper and reused it.

I almost ran whatever oil i saw wasn't gonna be yamalube until i spoke with james and saw pics like that yamalube and oem filters is what James recommended to me.

This clutch has around 3 -3.5k miles on it. The coloring in the housing is just a little glazing and not ridges. Yamalube only!

looks like you need to replace wet clutch how much wear did your clutch shoes have

The clutch shoe was micro metered and has around .2mm of wear, the best we could tell. Better than half the wear shoe is still left on the clutch pads. And this is after 3k miles.

i just installed my slugs and im all good. Just regular wear. Yamalube oil only. and i also greased the "greaseless sheave" since i was in there, again yamalube sheave grease. yamaha know what there stuff does. i dont see a need to change

Bravo, I agree totaly!!!
