Went riding this weekend and my buddy owns a CRF450R and my YZF426 clutch is so much HARDER to pull in than his clutch. What's up with that? I am thinking of doing the clutch mod on the assembly by the engine. Anyone have success with this? Does it work? If not is there another way to decrease the pull on the clutch lever? It's just hard because I have to feather it a lot around corners and such to keep it from stalling and after about 2-3 hours of trail riding it gets to my fingers. I know I probably need a heavier flywheel which I am going to look into. But in the meantime, any suggestions??

You can improve things by lubing your clutch cable. Use a cable luber like this one.

Also you can use the CR perch and lever or something like the ASV levers that use the CR pull. It is a different ratio than the stock YZ

You could get a Rekluse Auto and ditch the lever completely!

you could add 1/2 inch to the clutch arm. I did it to my '03 and it is pretty good (it's also pretty cheap).

Can I ask how you did this? Also, any pics? I'd like to do this mod as I see it as the only option to get that "CR" feel. :thumbsup:

Ain't gonna help much. The cr pull is like butter. Not sure how they do it, but pull any new CR or CRF clutch and it's like butter. The YZ/WR's just don't do it. The option I'm considering, which someone also recommended in this thread is to extend the actuator. I WISH Yamaha would address this one of these yrs. :thumbsup:

Anyone have the link to the directions on how to extend the actuator?? I know I have seen it on this forum before. :thumbsup:

BTW, I have lubed the clutch and cable but still harder to pull. :thumbsup:

Maybe softer clutch springs would help? I know, my 02' yz250f & my 03' yz450f have stiff clutch pulls. I was going to post on this issue too. I appreciate others feedback.

does anybody know the diameter of the crf450 clutch? (and the yz450f?) ...

its all a matter of torque, and a larger diameter clutch would need less spring force for a surtain torque ....

without knowing the diameter of the yamaha and honda clutch its impossible to say something about why one is easier than the other ...

On an '03 YZ450, I would tell you to get the GYT-R (Hinson) clutch kit. Mine is a two finger clutch that will work beautifully all day long, no matter what.

I know there are things you can do to get this kind of performance from a 426, but the particulars escape me. Either search for the '01 clutch mod, or PM to Cowboyona426 and ask him to respond to this thread.

I pulled the actuator arm out of the cases and gave it to a welder friend. He had already lengthened his on another '03. He added 1/2 inch of thin plate in the middle of the arm. Pretty simple mod. The clutch pull is lighter but the lever pull is longer as well (which is a downside to some.)

I have also seen/heard of guys just redrilling the lever hole (where the cable attaches).

Run a search, there must be better posts from people that know more about this.

Pick up a new clutch cable and you'll be suprised with the difference. I have a 05crf and a 03yzf, wacked the new cable on and it's better than the crf.

I have a new 06 and while it's smooth, it's too sprung. A new cable isn't what this thread is about. Try a new CR and you'll see what I mean.

Thanks, that's what I figured. I didn't think that while solving one problem, it may create a new one - the lever pull. hmmm...I'm really thinking the hydraulic clutch option sounds nice.

I've seen these GYT-R clutch kits on the Yamaha site and they are very expensive.

On an '03 YZ450, I would tell you to get the GYT-R (Hinson) clutch kit. Mine is a two finger clutch that will work beautifully all day long, no matter what.

What year 426? If it's an '00, do the '01 mod and install a new cable.

I have an 01. I don't think the cable would make a big difference. Maybe the way it is routed? Not sure what you mean by the 01 mod? Is that the drilling of the lever or the extension of the actuator? :thumbsup: I would like to hear from people to see if both of those together work well or not.

No, the " 01 clutch mod" upgrades the 00 to the 01. Since your bike IS an '01, nevermind. Try drilling the lever. That will be the easiest and cheapest to do first.
