Well I did my conversion today. As usual, a job that's supposed to take 20 minutes took me considerably longer...
A little background: I had stripped the threads on the front cylinder ACCT by over tightening the cap bolt on my first attempt at the Grambo trick last fall. I put a gob of RTV on there to hold the bolt in place and keep from leaking oil, and I have to say it has held up. I know I need to tap new threads into it and have already purchased a kit doing it. At the ACE hardware store I picked up the following: M6 x 30mm allen bolt (they didn't have it in 40mm size) 1/4 inch flat washers, neoprene washers, hex nuts and nylon lock nut. They didn't have the exact size neoprene washers wib recommended so I got something close. For the front I picked up a M7 x 30mm hex head bolt (they didn't have allen bolts in M7) I later had to go to Autozone and get lock washers and fender washers.
I tackled the rear first. All the ACCT parts worked just like they were described here and in the video. I inserted the allen bolt with the 2 neoprene washers up against the ACCT housing, followed by the 1/4 inch metal washer and the nylon lock nut. With the 30mm bolt there wasn't room for a regular nut too, and I honestly can't figure out what purpose it would serve. I ran the motor and adjusted till the knocking was gone.
I took off the front, disassembled it, and put the housing in a vise on my work bench. I have never tapped threads before. I figured out I would have to drill the hole a little bigger, the realized that while I am drilling for an M7 bolt, all my drill bits are measured in inches. I tried to eyeball it, holding drill bits up in front of the threading tool. I started smaller and worked my way up in drill bit size and finally was able to cut threads into a 15/84 hole. I washed the shavings out with brake cleaner, put the M7 bolt in there and it was actually a little jiggly in there, and so I'm a little nervous about how well it's going to hold up. Down the road I may pick up an 8mm drill bit and cut some M8 threads on that one.
Took it out for a ride and immediately noticed how much quieter the motor is. I hadn't even realized it could be this quiet! The ride was uneventful. I got back and decided to change my oil. After that was done I checked and the rear one (the one that points down) was leaking from the stem bolt. I put a metal washer next to the ACCT housing so it's up against the o-ring and added a lock washer next to the locknut. Still leaking! After dinner I put RTV on the threads in front of the locknut and where it goes into the ACCT housing. Hopefully it will do the trick!
