    This is what I came up with for a swing arm.. 32mm X 3mm stainless
    steel pipe with 16mm solid bar for the shock mount... 3/4" axle..
    Has a 3:1 leverage ratio on the shock....

    Ok.....I finally got some work done on the bike. I built my hinge and made some pins. I got the main part of the frame built. I will be adding more to it once I figure out how I want to build the body. I mounted the swinger. I still need to fab up a swing arm brace/fender mount. and The shock mounts. It acts like a leaner right now since I dont have any struts on it yet. I rode it around the house like this................that was creepy feeling! I dont think I would like a leaner. I hope to get some more time to work on it this week.

    How much lead have you got on the side car wheel.?..
    or percentage of bikes wheel base..
    It looks a lot in the pic... but photo angle maybe misleading..

    Its around 9.5 inches. I'm new to this so I did a bit of research and talked to some people with experience and this number seemed to be in the sweet spot. What do you think?

    I had 200mm / 8" on mine... And it just wouldn't turn..
    I pushed the unit around in tight circles on the lawn &
    you could see the car wheel being pushed sideways..
    So I changed it to 100mm 4" lead that more than halfed the
    side ways push on the car wheel.. And it goes around corners now..
    you really need to make the car mounts adjustable so yer can
    move the car back and forth to "tune" in...
    The rule of thumb is no more than 15% of the bikes wheel base...
    The altimate is to have the bike and car wheels in line..but that
    has a few weight issue..IE .. car and bike wanting to tip foward..

    well, i did some work on the hack today. i'm kinda treading water though. i changed my mind on the mounting system. i did manage to kill 2 birds with one stone. i wanted a wider track width and i also wanted to be able to adjust the toe i got rid of my pipe hinge and went to a more conventional adjustable setup. it added about 5.5" to the track and bow i can adjust the toe. it is also much easier to remove the car from the bike now. i will get some better pictures with my real camera tomorrow.

    Well I got my body! Thanks to an awesome member of the AVrider forum(zipper241). My dad was nice enough to let me use his jeep with a cargo tray (and big sunglasses), and ride up to new york with me to pick it up. I will post some better pictures one I set it on the frame. It need some work but it is solid. It came with a seat and a rack. It also has a very nice cover with leather straps. Someone powder coated it without finishing the body work, so I will need to grind some of it off and finish it before I paint it.

    I really dig this build, and I am not trying to be critical or anything. This is an honest question. :p

    Anyway, I likely don't know what I am talking about, but I have heard that leaners are not so great in adverse road conditions, snow and mud and such. But given that this is a dirt bike, I assume that you plan for it to see some adverse road conditions. Are you going to be installing a strut of some kind so that you can lock it rigid when you have to ride through the snow or fly the chair over boulders and such?

    Valid question, Its not a leaner.....This is just all the farther I have gotten. It will be a solid mount.

    I have been planning on making it a solid mount since the beginning of the project, but I rode it around the house a few times as a leaner, and It scared me to death! I dont see how anyone would be able to ride something like that at any kind of speed. It felt sooooo strange. I know I would die if I rode it like that. if felt like it was trying to fold me in half whenever i stopped or tried to turn.

    Hahaha no problem.....I was just waiting to get my body before I made the struts. I just didn't know how everything would line up. I didn't want to have to do it twice.

    Here are some pictures of the body just sitting on the chassis. I will need to modify/add a few things but I should be able to make it fit without too much difficulty.

    Gonna change the gearing or anything? I had to go down a tooth in the front on my CB400 w/Velorex, or it bogs down something awful in 6th gear (sure does wheelie good now when the sidecar is off though, lol). But then again yours looks like a DOHC if those round plugs under the valve cover are any indication? :lurk

    It is already geared super low for woods riding. It tops out around 55-60 in 6th as is. I have a bunch of different sprockets laying around. Im sure ill have to play around with it once the car is on it. I built this bike for going slow on back roads so im used to going slow.

    I finished the suspension and support struts.(Thanks for the shock Zipper!!!) I need to ad some bracing, finish my welds and mount the brake and body, but she isn’t far from being on the road. It was fun to finally put some hours in the garage. (I had some time off work) I took it out in the snow for a bit. I was very limited on space but it was fun!
