how to ease clutch pull

[Clb33fyxj]

ive got the magura on my 426 and i dont think its really worth the money. especially since i had the older style master cyl which was a total pos. the new master cyl is better. its nice to have no cable adjustments and the pull is very smooth through the whole range, but its really not much lighter than stock...

If your made of money you could get an adige slipper clutch. The inner hub is machined like a helix so it locks the plates together on acceleration, but makes the clutch pull super easy when you pull it in.

i still think the MSR is the best bang for the buck.

you can get either a shorty or normal. even though the normal one is slightly shorter than the stocker. but it comes with the mount and lever. up to 33% reduction

gbalias,

I totally agree. My buddy has an older 94 ktm 440exc. before it was like pulling in a clutch on an old harley or something.? he put that MSR clutch perch and lever assy on it was like i was pulling in the clutch on a 125.? soo easy. he didnt even clean the cable or nothing. just slapped it on. After that I was like that what im putting on my bike.

MSR pro raptor easy pull lever. $45.

ive got em on all my bikes and would never go back. it gives you 3 selections.

Yep! I went to that one years ago, really helped.

Go ahead and do a cable maintenance to (clean and lube). I like to use Teflon....can't remember the name of the stuff right now, used to use it on mountain bike chains, white liquid. I soak the inside and hang it up to drain and dry. Run a little don the cable, rub it in with my fingers, let dry and reassemble with the MSR lever.

Try a Motion Pro cable, or Sunline cable with teflon lining combined with an ez pull cr type clutch perch.

my 03 yz 450 clutch pull kills me I lubed the motion pro cable which helped a little bit. Is there anything else I can do ?

Hi. I just came across this thread. On an older bike like an 03 I would be looking at the clutch basket for wear/grooves. The plates wear grooves then get stuck in those same grooves when you pull the clutch, making it much harder to pull.

mine was hard to pull un till i filed down the notches on my basket,or if it is bad enough replace the basket

Sorry, but that has no effect on clutch pull. The manual linkage only moves the pressure plate. The plate stack separates itself from the lack of pressure on it. A grooved basket can cause a clutch to release poorly (drag, creep, hard to find neutral), slip, and/or chatter/grab, but there is no direct feedback to the rider.

Thats what I was told but yeah it would only make a difference to the lever feel when releasing the clutch.

What about the mechanism that pushes the rod accross to the pressure plate? Can that wear over time and become less efficient? I think there is a bearing on that peice aswell.

[Grizzalo]

Anyone know? Grayracer? Can the mechanisim that pushes the rod wear and increase clutch pull?

The "mechanism" is simply a cam on the end of a shaft. It's hard to imagine that it would.

The springs might be at fault, too, but it's more likely the cable.

The GYT-R plate kit for your bike includes a different clutch arm with an increased leverage factor. Mine had this, and I could never understand what all the fuss about clutch pull was until I rode one without it. You can also extend yours or modify the lever itself. Unfortunately, the arm is not available separately that I know of, but if you feel adventurous, you might try using the arm from an '05 WR450 (5TJ-16381-10-00) The WR uses a clutch cable with the same layout (runs down behind the engine) as the '03 YZ450 did. The arm has a different PN than the '03 arm, and may result in a softer pull. I haven't tried this; it's just a guess.

[Grizzalo]

Hmmm. OK. Im just thinking of all the possibilities that could increase clutch pull on a used bike. So basically, if you replace the clutch cable it should return the clutch pull to how it was on the showroom floor? The springs can only get weaker and the plates wear down so I would imagine they could only make the clutch lighter over time. Or can the plates warp and make the 'stack' of plates as a whole thicker?

The springs can only get weaker ...

You're certain of that, are you?

[TIG88]

Haha, when I opened this thread, I had the intent of posting a picture of those!

[Grizzalo]

You're certain of that, are you?

Not at all. Just assuming they would. Why would'nt they?

[grayracer513]

I'm not sure what's required to cause it exactly, and it doesn't happen often, but I've seen springs stiffen with age.

This is not to be confused with how a clutch that uses a diaphragm spring stiffens as it wears. I'm talking about coils and leafs.

If the bike is an '03, I would look into replacing the cable and routing it like the improved design of the '04. Yamaha made a change in cable routing betweeen those two years.

They did indeed, but the WR kept the old routing because of where the E-Starter sits, and you don't hear too many complaints about that clutch. That's what set me thinking.
