Default A.I.M. Clutch set up

This is basically how I set up the aim clutch in my bike. I did not come up with any of this information, it was all given to me. And I have most likely butchered the original information giving to me. Haha sorry. If he wants to jump in I'm sure he will. After installing and tuning the aim I ended up with very consistent et's and 60 foots for a "street bike" set up. No bar, two step ect. Another thing this set up does is that when you have it close to dialed in, the bike does the same thing every pass. As the man always says, "you need to know what the bike is going to do when you drop the hammer" and when that happens you gain confidence, can concentrate on the light and usually get quicker the more you use and tune it. Sorry for the crude video. I had a handful of guys asking about it. And didn't really want to post it on fxxkbook.

This set up is also awesome for street bikes. The lever on my hot street bike is way softer than a stock 883 clutch and the clutch was still holding at a 131mph at the stripe in 5th gear. You most likely wouldn't know it if you were on a bike with this set up, except for the lever.

Nice job madnss, hope you don't some input, I would like to add that these springs a very unpredictable as far as rate to height. I like to get the rate of the installed height and use that as a baseline. You can add or subtract stack height or pressure plate thickness to change the spring rate to a known number or change the spring. Had combo's ready before T&T so we could just swap parts and know exactly what we had. Sounds like a PITA but once you get it you really don't do much.

Anytime you can chime in!

Rate of the installed height. Please give that to me in Laymans terms. You've said this a million times and I can't get my little melon to grasp it.

So clutch plates and pressure plate measured and then measure spring load like I did? Because thicker or thinner clutch pack will change the rate of the spring?

do you measure spring pressure with the package all together?

Measure stack height + pressure plate thickness + lock up ring thickness equals whatever. Measure the clutch hub from the back to the retaining ring. The difference is filled by the spring. That's your installed spring height. Let's say the spring is sitting on the work bench @.250 spring height. Installed it's at .180 spring height, Collapse the spring .070 and that's the installed spring rate. Go up and down .010, .040, .080 and you can see what the rate would be if you make changes. I'll have Matt shoot you a pic.
