Muller Power Clutch

[MMARVINxb9]

anyone ever heard of the muller power clutch for the 03 buell xb9r, it allows 30-40% easier clutch pull or have it on there bike? Is it worth the purchase?

it's a well done piece....have sold and installed a few...but never on an XB.....only big twins with heavy clutches and sportsters owned by women battling carpal tunnel problems. not kidding.
in all honesty an XB with the stock diaphragm clutch, amsoil in the trans/primary, a well lubed and properly adjusted clutch cable, and a factory perch/lever that is lubed and adjusted properly has a very light and nice clutch lever pull. no need for a muller IMO.

Thanks for that man.

What John said! :up:

I have one installed on my xb9r. I also have a brand new stainless braided barnett clutch cable (lubed) and stock lever (lubed.) I run Mobil 1 in both holes. Everything is adjusted properly--cable, chain, and clutch. I notice an estimated 10% less pull action. But, if you check off the things John said, then you're probably fine without it.

I ran one on my old 04 XB12S.
Did I notice a difference? Yes.
Was it 30-40%? Probably not. Felt more like 10-15% Maybe.

A well lubed and properly adjusted clutch cable, ...

I wanted to lube my clutch cable while i had it out, but the mechanic said the Teflon would swell up and the cable would end up pulling worse. Is there some kind of special stuff to use?

 

[rchuff]

^^^^ Never heard that . Use cable lube.

 

[34nineteen]

I'd never heard of that with Teflon. I'll have to check out that Inox cable lube, though.

I used grease for mine, not oil because it's teflon.

Exactly that. He said the teflon inside the outer cable will swell up. At the time I wanted to use cable lube. Especially for motorcycles. How did you get grease inside the cable?

 

[Simplymichaeljr]

Just grease the ferrules and moving parts, that was the directions included with my barnett SS braided clutch cable

So, I just replaced my cable with a new one, and put new OEM levers on my bike, running Formula +, and John is right, I can pretty much 2 finger this clutch lever. I guess all of that little bits of friction add up.

I've had pretty good luck running Formula + in my bikes, and I may have to try out AMSOIL. Maybe one day I can prove John wrong (but probably not!) :black_eyed:

lunaticfringe = spot on.

you summed it all up aaron. applicable to any cable operated cycle clutch. between the perch/lever....the cable...the actuating mechanism...and the pressure plate or spring....friction in ever increasing tiny increments all adds up. an XB with all the items checked/lubed/adjusted in the order that i mentioned always results when properly performed in a light lever pull with nice, smooth consistent engagement. a major player in the entire episode is the diaphragm clutch pressure spring. it's a very nice piece.

Its funny, as I can swear I can actually feel the "wave" as the diaphragm spring flexes.

Do you know if there is a suitable replacement bushing for the clutch lever pivot? It doesnt show one in the HD/Buell books, but I'd imagine that bushing may be available for some other brand who uses a lever from the same factory? My current bike had a set of CRG levers and the clutch pivot hole is all ovalled out. I think I may have found a nylon bushing to retrofit into alloy to steel pivot pin interface. If longevity of the nylon is poor, the upside is that they are inexpensive and easy to source, until I can find something else that could work.

I ponied up and bought a set of OEM black levers from Lance for now.
