    Default 1983 FXRT Build: First Foray into American Motorsickles

    Picked up this ole gal today. It's an '83 FXRT in a Paughco rigid frame. I don't know exactly what frame, but I'm assuming it's lowered and raked. She needs a good going through, but will hopefully be a good candidate for my first shovel.




    She runs, but only if you play with the choke, so I assume the carb is all gunked up. Pulled it off and am ordering a rebuild kit. Anyone know exactly which model carb this is? I assume some sort of Keihin CV? It's got a Screamin' Eagle air cleaner if that helps identify it.









    It's got dual plug heads and dual coils, which is why I suppose it has this ignition. Never seen one before, any thought on it?



    Plans are first to strip it down, and fix any dumb shit I find. Once she runs reliably as is, then I'll start modding it. I only had it running for a few minutes and it's puking oil out the back from some hoses. Have to trace that down. The main thing I want to change is the primary. I gotta have an open belt drive, but that leaves me with a dilemma. Do I get a nice cheap, clean, kicker-only belt drive, and an expensive Baker kicker for my 5 speed, or do I get an expensive and not so clean belt drive that accommodates the electric starter? Will this weird ignition even work well with a kicker?

    4K. Shovels tend to go for 4-7k where I'm at. I figured 4k was a good deal if it came with a rigid frame already.

    Yup, Keihin CV. Look up that part # to identify model.

    Keep that carb, just rebuild it, it'll work nicely for that kick start

    im not a big fan of electronic ignitions for kickstart or in general for a bike that your going to be riding, with that said, others swear by them and thats fine as well. I just prefer points.

    i prefer the narrower BDL 1.5 open belt drives, only like 300 dollars too

    if you go open belt you will need to either 1) create a small catch can for the crankcase vent tube that normally lubes the chain drive inside the primary or 2) put a small filter on the end of an oil line of the crank case vent, either way, do not cap that crank case vent, your bottom end needs a way to release pressure.

    Thats a great deal on that bike. probably would have gone for 5-6k in my area. looking forward to seeing what you do with it

    There is already some fuckery going on with the oil vent lines. Wasn’t leaking in the guys shed I got it from, and wasn’t leaking until I ran it. It ran for maybe two minutes, I put it in the garage, and then it leaked a bunch out. Hoses and the rear of the oil bag where the filter is are all oily.

    It’s got dual plugs, so I think I’m stuck with the ignition. As for the belt, I definitely like the 1.5” kick only kits, but I need to figure out if the F5K kicker will work with this trans. It’s the factory cable clutch 5 speed.

    Puking is typical. Harleys with oil tanks higher than the pump wet sump when left to sit.

    Baker kickers fit 1990 and up so no joy. Either swap trap door and whatever else is required or replace transmission. Contact Baker tech support.

    It’s like 1/4-1/2 qt. Seemed like a lot to me. As for Baker, I contacted them, but no response yet. I figured it wouldn’t fit because I didn’t see a hole in the top for the clutch arm to go into.

    I just got a response from Paughco. It’s a straight leg frame with a factory style neck, zero stretch and a 30 degree raked neck.
    Set up for a 5 speed transmission and chain rear drive, obviously. What length front springer ya’ll think would look good with 30*? I was thinking at least 12 over.

    Wait a minute... isn’t 30* stock? Why does my shit look so raked? I’ma have to look at the triple tree more closely. Might have some weird raked shit on there.

    Took pictures of the forks vs neck. They appear to be parallel, so I would assume there's no stupid rake kit on the fork. Perhaps someone cut/raked the neck, but doesn't appear so. Maybe it's normal, but I'll be damned if it doesn't look raked out.

    38 or 39 degrees would be my guess ...

    You are not stuck with that ignition. I used to run a dual-points setup on my shovel, and later swapped it out to a Dyna S single fire. Get a Dyna S if you want a different ignition.

    The trees look like stock FXRT and appear parallel to the neck. The neck certainly appears raked.

    If you level the bottom frame tube and check with a digital level you'll find total rake. The little digital level cubes are handy for that sort of thing.

    What I see in your pics is how the tube at the bottom of the neck is bent, and looks long compared to the Paughco catalog for a stock 30 degree rake.
    Is there a part number on that frame? Just wondering how Paughco supplied you with the frame details.
    #S139 is what you were provided.

    In their catalog, I see rakes available in 30, 35 and 40 degrees, with either 0, or 2 1/4" up:

    I emailed them the serial number on the neck and they told me the date/specs.

    That’s all Paughco told me. I emailed them the pictures today and they said it was definitely 30* when it left the factory in ‘94, so someone has modified it.

    You'll find out when you take the bike down for paint if ya can't see any mods as-is. I have mine sand blasted by monument companies since they have manly blast pots and engine-driven compressors. Gets any body filler etc off nicely.
