    (One of my locals doing modern bikes uses a CO2 fire extinguisher, and can tell which side of the bike maybe...)

    You don't want to take it back apart do you?
    Better to find it now on the bench?

    PS: Interview? Article?
    Not to worry! Like I said, one of us will be pressure testing it. I was just mentioning that I have had good luck with propane, too.

    And yeah, a few years ago I interviewed you for an article I wrote. I'll PM you to see if I can jog your memory.

    I admit, Govmule84,

    Propane is the best way to check for leakage at the carb/manifold junction, and throttle shaft, as they cannot be bubble-tested.

    I just hate for you to assemble twice, when you might sleep better after a check on the bench.

    PS: I didn't know I did interviews (other than that assault charge thing....)

    It better not have a photo of me.

    PPS: Got your email... (in my spam filter!)

    That was an "interview"?

    Let's get this baby ready for a drivetrain, huh?



    Only needed one little shim at the left rear corner.



    Gah, that magneto looks new. I was supposed to have a crunchy-looking one, but things didn't work out. I'll ride it, it will look like garbage soon enough, I'm sure.



    No idea what the hell this throttle arm is. The "right" one don't work. (Carb is M74B)



    Repop exhaust hung. No muffler right now. I gotta figure something out there with that. Oil lines in place.



    Hideous generator in. (Go ahead, Cotten, tell me how ugly it is. I know. I have the original 32E rebuilt and on the shelf.)



    Next we're on to primary and clutch... after that I need to hang some tanks, wire it, and start kicking...

    Primary is in. I used a reproduction inner primary that came with the bike in as-new condition. Man, what a hunk of junk. The bottom tab didn't/doesn't line up at all, and the OEM outer cover didn't really mate up well to the inner... what a pain. I got it close enough, so that's that for now, I guess.

    I loaded in the clutch and buttoned up the primary. I got the tanks hung and the speedo is back on (but like all the handlebar wiring, none of it is hooked up nor functional.) Saddle is on, but I had to order a seat pin for the toggle link. I need some other knick-knacky stuff... an element for the air cleaner, a final drive chain, and my shifter linkage was also kind of all shot. After I install that stuff I need to run a little wire, slam a plate on it, and load it up with fluids...

    Looks great Liam. The end is in sight!

    Why not use the original timer? It will start easier and look better, and run just fine!

    Thanks, Robbie!

    The end IS in sight! I'm getting very excited. With respect to making the bike more original... I'm with you. Sort of. I still have the timer. Going to rock-stock is definitely a possibility, but as I progressed with this bike, I realized that there were a few things that would never be "right." (The trans, the carb, some other bits and bobs.) I certainly am not out to make it a chopper, but since I have some original pieces and they can be swapped easily, I became more OK with the idea of making a few reversible changes. I doubt it will ever be all-'47 under my ownership. Hell, I don't even know enough to make it "right." But I made it better and it's almost roadworthy again, so there's something to be said for that, I guess.

    The main reason for the mag is simplicity. No battery to go flat, no wiring harness. Some day I will find a siren and the electric speedo lock thing and pull the handlebars apart and wire everything "correctly," including the ignition switch, but for now that stuff is all just non-functioning bolt-on decoration as it was for the last fellow who owned it. Since none of those items are close to being in service, it just seemed a bit simpler to slap a magneto in it, run a wire from the genny to each light, and call it a day.

    I'm not ruling it out totally. I want to get it rideable for the time being.

    But since you asked, let me return fire on a question... does the timer care if it's 6V or 12V?

    The timer doesn't care what voltage battery you have.

    If I'm not mistaken, that' an aftermarket direction-reversing bracket for use with a 'pull' spiral.
    Does the inner wire push or pull when you twist the grip? Perhaps the spiral has been changed to a 'pull' spiral, which often happened in the chopper days when running 'alternate' carburetors.

    It pushes. I would like to see the correct arm just for reference; nothing in Palmer's book looks like it would work to me. I can't really find a photo of anything that looks about right. Maybe I have the cable routed incorrectly.
