Hey everyone, I’ve been tossing around the idea of a doing a full fiber mod on my 09 raptor with the big 3. It has close to 10k miles on the factory clutch, and it’s still working great. Never slips. The only thing I ever do that may stress the clutch is climb coal hills. I was planning on just buying a single fiber from Yamaha and keeping the rest of the clutch pack original (assuming it looks good upon tear down)

My question is, how do you guys like the clutch feel? I understand it will be a harsher engagement, but how harsh? If I rode sand dunes all the time, it would be a no brainer. But I don’t want to have to fight the clutch on hard packed surfaces. I am a very experienced rider, so I can deal with man handling the clutch as long as it’s within reason

Clutch control over technical areas is another concern, because I do deal with rocky terrain and things like that here in PA

Any thoughts from people that have done this mod?

My 700 has the stock clutch, but I have ridden others with aftermarket ones(same aa full fiber mod), and they work great, no issues at all.
And 10k miles on your clutch...I would just replace the whole thing.

Its the heavy duty springs on the clutch pack that make the difference in the feel on the clutch lever, engagement is no different. Its nothing that will make it feel like you have to man handle it and worry about getting sore. As @Sixpack577 stated, replace all the fibers with new and soak them overnight before install. I suggest getting with Cuervo racing or look on his store on Ebay and get the reuseable gasket for the clutch side assembly. I went with an OEM once and it leaked on me, no issues with Cuervos version.

Thanks for the replies, I’m going to go ahead and do that. I already have an email into Cuervo to find that Cometic clutch cover gasket. Is this the right one? I’ve heard you can’t find them anywhere but from him, but it looks right



I just had an issue with my 07 raptor where the factory gasket tore internally (never was opened up, failed on its own). When I changed the oil, none came out when I took the filter cover off. So this mod is worth it on my 09 just for piece of mind for that reason

I think I’m going to stick with stock springs, I’m not pushing enough power to merit stiffer ones, and I want to keep clutch pull pretty easy

That link you posted was not the one I received from Cuervo. You might have to call him direct from his FB number and ask for the gasket you need.

Is there any kind of break in procedure for a new clutch? Maybe changing the oil at a shorter interval after install? I’ve been changing my oil every 30-40 hours. Ok to go synthetic right away?

Yes and yes
Change the oil sooner and synthetic is fine, just soak the fiber plates in it.
