Default AIM Light Force Review & Tips

Let me start by saying that I typically don't start/create review & tips threads, but being that there is a lot of chatter surrounding the AIMS Light Force I opted to start one.

First AIMS seems to be understating the 40% decrease, its surely feels like well over 60% decrease and the friction zone feels like it does on the Twin Cams. I initially thought that the line was "air-bound" and re-bled it twice because the clutch pull felt so much less than OEM. Unlike HDFBagR (another thread) my AIMS hydraulic line connection did not look like his, so I proceeded with install.

Second, I am a lazy f*&^er and just decided to loosen exhaust rather than completely remove it. I loosen heat-shields to get to manifold nuts, right muffler mount, mounting nut that hold header to the frame and cross-over pipe mount. I left the right floorboard alone, though I probably should have removed it. Once everything was loose, I took off the slave cylinder cover and had to jiggle it out from between the engine and header. I removed the hydraulic line from the OEM cylinder then removed the 3 allens holding it in place. Once removed I noticed a SUBSTANTIAL amount of oil (not brake fluid) behind the cylinder! Sorry no pics.

I then placed a coating of oil around the rubber seal on the AIMS and bolted it in place, along with connecting the hydraulic line. Please be very careful as the instructions state, I can easily see how cross-threading could occur. I proceed to bleed the line, probably took about 6 minutes. I then started the bike in neutral (yes with the headers still loose), pulled in the clutch and put it in gear. The bike start to slowly move forward and I continued bleeding. Tried it again and all was cool. Just like in the other thread my hydraulic line did note pass directly through the notched portion, but I was still able to get the cover back on.

All together about a 2 hour install with a brief test ride. Would I recommend it? Yes if you have hand issues like myself.

Just got back from 100+ mile back road jaunt and my left hand feels great. If anyone has hand issues (arthritis, carpal tunnel, etc) then the AIMS is the ticket.

I do a lot more city driving during the week than long riding. This sounds like it would be great for me.

Should be perfect for you. The f#$ked thing is...the AIMS slave cylinder works off the same principal as the OEM, it just has move surface. Why in the world couldn't HD engineers have developed something like this. Hell, after the 1st test ride of a M8 they must have noticed that the clutch pull (and friction zone) sucked.

been off of the forums for quite a while. When I first bought my M8 I noticed right away that the clutch had to be let out almost all the way before it would grab. I just bought a 2004 Deuce CVO. I was surprised to find that it had a hydraulic clutch and when I took it for a test drive she almost threw me off because the clutch grabbed right away. I noticed the ease of pull was really very nice too. I liked the bike so much, I bought it. So, this recall is all about the clutch slave and the AIm clutch is like my Deuce? would Harley install this one instead of their fix..... I dont care about the warranty anymore....... my bike is almost out anyway.

I tried to make that pitch to my dealer and they said no. It is a safety recall, so I guess I understand why.
