    Thanks HRK & Chucktx. After looking up those part numbers, HRK, I've discovered that many automotive & bike parts are interchangeable. Stuff at car part stores are sometimes cheaper and usually better quality. For instance, I got an Accel point/condensor set (high performance) that is way better than the ones I had. On the points I had, the contacts didn't quite line up and the spring was weak. Got that tip from a biker who'd been using them for years on his shovel.
    Chuck, so maybe that's why they put the caliper in the upright position to start with. I had to angle mine back farther because of the fender brace. Thanks for the tip - I'll use it.

    I remember the picture you posted; the one by the brick wall. That was a cool bike. Do you still have it?

    Just like I hope mine will run! Hate to sound stupid, but what size brake lines do I use? I'm going to make my own, like HRK recommends (much cheaper, as J&P wants about $30 per section for braided lines). I went to Auto Zone the other day, thinking they were all "standard", but I had a choice of 3/16", 1/4", etc. What size do I need to get? I've ordered a brake switch, an elbow for the master cylinder, & a tee that will accept the hydralic switch. Do I need to get a third section made out of rubber for the rear caliper so the wheel can be adjusted (for chain stretch when needed)?
    Incidently, My exhaust is on the way from J&P. I went with 34" drags with 10" baffles. I've been told that since I'm using the old butterfly Keihin, I should be able to tweak the carb to match the custom exhaust without changing jets. The older carbs didn't have the EPA restrictions the newer ones do. Any comments?

    get the nuts that screw into the calipers/master cyllinders and use that size line.... ya can find a short length of front rubber brake line that is used on cars, it will work for the rear caliper.

    Holy Cow! Now look what I've done. While pressing in the inner primary bearing, we went too far and busted out the shoulder on the inside. The bearing & seal are in. I have no idea what to do now.

    well, not sure you can run it with it like that without rising
    the bearing pushing through and walking, if it does the main
    seal could go and you get a leak

    On the other hand you might see if a shop that welds
    aluminum can lay a bead in get that back in place, but it's awful small

    Either a new backing plate is in order or a belt drive inside with no fluids

    What if I pressed the bearing & seal out and ground off the remaining material and made a steel "gasket" like the one I drew. Maybe about an 1/8" thick and bolted it on. It would be a bitch to make, cause I'd have to make it by hand, but I think I could do it.

    Why does it have to be that elaborate? Couldn't it just be square with a round hole smaller than the bearing race, and with four bolt holes?

    Sure, it could be square. On closer inspection, a lot of the supporting shoulder was sheared off and the bearing is now cocked in the hole. I'm thinking I might have to get another inner primary after all.

    a thought.....i dont have it in front of me.......grind the shoulder square and flat and use your washer made by a water jetter. or maybe use some stainless fender washers to hold it.....also you can centerpunch the inner surface of the housing before installing the bearing, using bearing locktite.......

    I talked with a machinist yesterday afternoon and it appears it would cost about the same, maybe more, to have the washer made and have him grind the suface flat, as to just get another used inner primary. I may go that way and next time be more careful installing the bearing. The mistake we made when we installed it was not putting any support directly beneath the shoulder. My friend (who has the hydraulic press) used an oversized socket underneath that went around the shoulder and came up to bear against the area where the 4 bolt holes are, and so when he levered the bearing down and into the housing, he punched through the shoulder. I told him it was aluminum & to be careful but he went too far. He was really bummed about breaking it. Ah, well, s*** happens. I'm gonna start looking around for another used inner primary. Maybe I'll get lucky and find one with the bearing and seal already installed.

    You can make that plate yourself

    Get some metal at Lowes, cut a square
    drill 4 holes for bolts, then get a whole saw
    and drill out the back,

    It's just for support, and will hold in the seal
    as long as the ID is narrower than the od of the bearing
    and wider than the main shaft you should be fine.

    This should be a $10 fix (unless you have to buy a drill press, drill bits, compressor,
    pain gun, tapcon set etc)

    BTW be sure to get some black sillycone for around the bolt heads
    when you tighten it up or you'll be dripping oil...

    Okay. BTW, the bolts don't go all the way through so I don't see how it will leak oil. Good news: today my rebuilt tranny arrived in the mail and it looks good and shifts smoothly, too. I also got a new kicker arm and a new mainshaft - no more wobbly kicker. They also put a polished side cover on (it matches my motor) instead of the crappy chrome one that was on it. I'm guessing that the internals were done right. the 6 month warranty (parts only) doesn't begin on the tranny or motor until I start putting milage on them. Now, I need to get that primary straight . . . HRK, what is a "pain gun"? Can I use it to end my pain? Ha-ha-ha!

    yeah use it to shoot that inner primary LOL

    I presumed the bolt holes went through didn't look that close so
    in that case, i'd do the following

    Remove bearing from case, putting some pressure
    on the cocked side to gently straighten with the press.

    If the shell of the bearing looks good and the case where it will
    sit looks good, put bearing in freezer to get it nice and cold, couple hours
    minimum, overnight even better...

    Now remove the remaining retaining clip ridge with a file
    or dremel, take your time and get it smooth and finished.

    make the plate out of some square steel plate thin from
    Lowes or Home Depot along with, a drill bit and a whole saw drill bit

    If you know somebody with a drill press that you can use, even better.

    check it for fit. Now install the plate and lightly heat
    the inner primary with a torch, then take the ice cold
    bearing from the freezer and install, it should pop right in
    no press needed.

    Remove the plate and install any seal and reinstall plate
    should be good to go..

    Or something along of that order of things..
