And the saga continues.
I emailed Garry and told him it was still slipping, he said and i quote "i thought it was a Sportster" WTF.
Any way he said he would ship me some heavier balls.
These arrived while i was away at work. Yesterday i arrived home for the first time in 6 weeks to find 9 balls in a bag, no instructions no anything just balls.
So i set about draining my primary oil again, removing the cover again.
Now i have 30 balls (lucky me) he has supplies 9.
So i email him again. Response.........space evenly.
Well it is all back together "AGAIN" and it has started to rain, guess i will have to wait another 6 weeks to see if this works. F>>>>>>>>>>>>>>>A>>>>>>>>>>>>R>>>>>>>>>>>>>>>>K

Did you think you'd ever get any directions ? Why start now? That's not fun

I wonder how the same size balls are different weight, i suppose the material difference but how much can it be? It never occurred to me to weight individual balls, maybe they were different. If they are, you should spread them evenly to keep everything balanced.

How many balls this thing take to operate? More than 9?

It takes some work to get just right.
When I first started adjusting mine it was engaging at to high an RPM.
The worst part was not having a medallion opening to make quick adjustments.
Draining the primary and opening it every time really sucked. I think I did it like 10 times before I had it where I liked it.
The balls he sent you are a heavier material to make it bight harder. I want to say Tungsten but I can't remember exactly.
I started with 6 of them but it was biting too soon so I worked my way back to 3 eventually.
I had to adjust shims as well before I finally got it where I liked it.
Now that its right though I love it and won't likely ever go back to a stock clutch.

Wow...what a piece of work! so I guess when Curtis says 3 balls he means only 3 of the heavier ones he used not 3 total. Cause you gotta have them all in there I imagine.
A few...

It's a really fucking bad ass idea, I'm sure once your dialed in its golden like Curtis mentions just getting there sucks. Would be nice to have a feather light clutch pull and not have to hold it at a light.

Thanks guy's for the encouragement.
Can't remember exactly the type of material, but they are certainly heavier.
Bloody hell Curtis, you know how to kick a guy when he's down, you mean i may still have to keep removing the bloody primary and remove some of the balls...............shute.
Anyway still raining and i have 6 hours drive ahead of me, so i guess i will wait for another 6 weeks to evaluate........again.

Bloody hell another up date.
It is now a year since i thought i had (with the great-full help of others) sorted this "THING" out.
This bloody thing is slipping again.
So i got a new clutch pack (Thanks Curtis again) sent over and proceeded to measure and set clearances AGAIN.
One thing i found was a 1/2 fiber 1/2 steel plate which i have put against the EMF, i have the steel against the Alum of the EMF, thinking at the time i didn't want a friction plate wearing on the Aluminum.
i remembered what Tapio said several pages back that he "welded the friction plate to the Alum of the EMF". This may be the problem.
It's not a lot of slip, and it gets worse as the day progresses, temperatures rise and beer is consumed.
Solution i think will be replace 1/2- 1/2 with friction plate, decrease gap of .05" to about .025" dry.
What have i got to loose?
1. Sanity
2. my usually calm exterior.
3. And maybe i get the joy and pleasure of pulling my primary off AGAIN (wish i got pulled of as much).

This an open or closed primary?
I pulled mine off of an open primary due to more wrenching than riding.
It would be ok if I only rode a little at a time but I used to just go ride and it was having me call a tow truck all the time so I went back to the stock open primary clutch.
I think it works great in a closed primary wet clutch.

Update #21
The clutch has been working.......ok i guess, up until now.
I thought i had it sorted, with the right set up/feel/ clearances etc. But alas NO.
We rode 3000klm in 5 days, while the thing didn't let me down completely, it did fault intermittently.
Sit at idle when cold i always use the clutch to ensure no jumping when i engage 1 st gear, after that it's all good.
I then switch between using and not using the lever, however sometimes even with the lever pulled in the bike jumps forward or stalls usually in heavy traffic or at the lights, very embarrassing.
Home now, and drained the oil...........perfect.
Checked the tension of the cable............perfect.
One good thing ................. it doesn't slip anymore.
So i have pulled the OEM set up out of the box and i think i will change it back to STD. After all i just want to ride not worry about leap frogging into the back of one of my buddies or worse someones Mercedes.
Anyone looking fro a $600 paper weight?

Can't remember and didn't want to have to read through the post again.
What oil are you running in the primary with it?

So the plates are stuck together for some reason. Either the EFM bearings are stuck on closed position, there is some shit between the plates or whole setup doesn’t sit right. What can you do? Open the EFM, check the ramps and balls, check the plates, check the EFM plate. Anyways Sorry to hear, I sure thought only ppl with open primary and EFM had such a problems.
I wonder how the balls and ramps would like ATF oil... at least that should keep the plates from sticking together?

Well my baker clutch is ok with ATF on the SG. When I was running the EFM we chatted about putting holes in to squirt wd40 on the ramps. He thought the aluminum would retain enough lubricating properties. It did not for the open primary. That same open primary is having clutch stickiness with the stock top fuel clutch. I am assuming that there is no place for the dust to exit. I will know more when I work on it, but that might be a while. The open primary is on my AIH so not a complete apples to apples.

That's why I asked what oil he was using with it.
I was running ATF with my stock clutch to get a better bite but when I went to my EFM I had to switch back to primary oil as it was biting to hard with the EFM. Once I went back to primary oil it settled down but I use Lucas Primary Chain case which is thinner than what many are putting in their primary.
