Muller Power Clutch - First Impressions
« on: December 21, 2017, 09:21:45 PM »
My dealer installed this for me yesterday. I could have done it myself, but chalk it up to laziness. The reduction in lever effort is quite noticeable, and the action is smooth. The adjustment is a bit tricky, but it is now where I like it. I haven't ridden it much, but I think I'm gonna like it. Someone asked for a clutch pushrod movement reading. I'll get to it one of these days. The unit is pretty pricey but worth it in my opinion.

What bike ? Ive installed several of the HD reduced effort kits ( ramps and spring ) on twin cams , everyone has liked them . Only worked on two bikes a Sporty and an Evo soft tail with the longer arms, both had adjustment problems .

Will it work with the HD hydraulic system and a VPC?
Can the friction zone be adjusted?

My bike is a '15 RK. It replaces both ramps only. They are differently designed with a slightly longer arm and bearing dimples that are closer to the center of the rotation. It makes quite a difference in lever effort.

I really want to try those ramps as my left hand locks up, especially if it's cold. I wonder if SE spring with the muller ramps is as easy as the stock ramp and clutch spring. I should put the SE spring in my '07, but haven't because of the arthritis and i'm thinking it might be just the thing. :scoot:

I have a SE spring with the Muller ramps, and I compared it with a hydraulic clutch with a stock spring. I could feel very little difference in lever effort.

Sounds good, I was wondering what to get with my "survivor" pool winnings, and what to do to the bike this winter. :up:

Like the reduced clutch effort but am having hell with the adjustment.  I have a SE clutch and have about worn out the derby cover trying to get it right.  About ready to go back to stock cause its a pain finding neutral.  Like my shovelhead before I installed a Pro clutch.  Best find neutral before you come to a stop.

Perhaps change your adjustment method

As everything expands and gets further apart when hot I adjust things cold so that there isn't much play at all, a hair at the most.

I slack the cable so that the ramps are free to move, then wind in the clutch release pushrod adjuster until it'll go no more, at that stage the clutch plates as viewed at the basket are separated as much as they will go, the ramps are also fully homed,

at this point the slack can be taken out of the cable and the lever operated, it's shouldn't move, any real movement indicates wear in the pivot point or the inner cable stretching or the outer cable jacket compressing, appropriate action can then be taken

after checking the cable I slack the cable to achieve a hair to 1/32 // 1/16 max at the lever

I then back out the clutch release pushrod adjuster, witness the plates make contact again, continue to back out the adjuster so that it's a hair to half a turn out from the ramp seat

this is on a cold engine so ensure it gets warm up time before getting up it

I only go through this full process once a year or if I've had the clutch apart or cable off, I then know where I'm starting from and any later adjustments are just the pushrod adjuster which is easy peasy

Granted the adjustment is tricky, as reported by the dealer. It took them several times to get it right. Actually I think they just wanted some seat time on my RK with the Tire Shredder kit and dyno tuned.  :teeth:

The Muller arm uses the whole release stroke to give a good clean release. The pushrod adjustment on the clutch pac and the lever cable adjustment have to be set to bare minimum clearance to allow the full stroke to be doing work. Any free play in either adjustment is dead time for the work portion of the release stroke when you squeeze the lever.

The difference between Harley and mueller is after you loosen the adjuster rod and turn in until it just grabs,you than turn it back out 1/8 turn. The harley is 1/2 to 3/4

I adjust the Harley 21 or 19 ramps at 1/4 to 3/8 turn out. That's how you get more push rod travel.

How does one determine what 1/8th of a turn is? Its easy to determine 1/2 a turn or 3/4
