    Hoping this thread will not only be a place to document the build of my CL175 vintage racer (or track bike?), but that it will also be useful to anyone else contemplating building a vintage racer or track bike. With any luck, others will post pics and videos of their vintage bikes or bikes they've photographed for the inspiration some of us will need. If there's a duplicate somewhere already please let me know and we'll change this one up.

    A few years ago the idea of a small cc vintage track or race bike entered my head and unfortunately, it hasn't left.

    Yes. I realize neither of those are Hondas.:D

    Not that I have any business on a race bike, mind you. I had, and continue to have a lot to learn about riding, nevermind racing. Perhaps that's what I like about a project like this: the learning. At multiple levels.

    A few more track days and a few more vintage racers didn't help the cause.

    [​IMG]

    I have a soft spot for Yamahas but I like all of them.

    [​IMG]

    Along the way I've also had a bunch of encouragement. Jon, aka Junkyard, is guilty of giving me a shove or two.

    [​IMG]

    As is Birdman. Here's his CB175.:tb

    [​IMG]

    There have been many others in the wings quietly nudging. Not to mention Sidecar Sue is always very supportive.

    Meanwhile, I work on learning how to ride. It's a painful I suck but fun process.:ricky



    Fastforward to about a month ago...an inmate not too far away posts up he has a CL175 kicking around that he'd like to get out of his way before winter.

    Like an idiot I immediately PM him that I'm interested if it's still available.

    It is.

    I'm doomed.

    :lol3



    After a few false starts we finally work out arrangements for pick up.

    This past Friday, thanks to chippertheripper, I moved one step closer to realizing a dream. Thanks again, Chip!

    There she sits in all her glory.

    In a little better lighting ready for the trip home straight through Boston.:eek1

    [​IMG]

    Luckily, my timing was good so Boston wasn't too much of a horror show.

    [​IMG]

    The natives may recognize that this was actually taken heading south but the northbound pics had terrible lighting.:1drink

    Pretty much got it home and tucked it away.

    With all the other activities this weekend it has just been sitting in the wings waiting to be stripped down. Working on a game plan on how to best approach this.

    I'm thinking getting it to run may be my first step.

    After that I'll start removing anything that isn't needed for the track.

    In between I'll continue to scour the web for CB/CL175 racer stuff. Motobits and Glass from the Past has some cool stuff that would look good in my stocking.:lol3

    But first I need to make a spot for all of this to happen.

    Looking forward to some input here.

    Stay tuned.

    I will enjoy this also. Let a buddy know about the thread as he's just started building a cb 160 race bike. Some of your photos aren't working, hope you can get them squared away.

    Cool beans EC.... :clap :thumb Glad you quit lyin' to yourself... :lol3 Good for you.


    Can't wait to see what you build.

    Just as an FYI, Glass froom the Past had quite a lead time about three years ago when I bought a seat pan for the CB 350... Just sayin'... Not saying anything bad about them, they make excellent stuff, just sayin' plan ahead. :wink:

    Carry on :lurk

    when i right click on the 175 images and say 'open image in a new window' i get them to appear.
    odd.
    Looks like it has great roots to build up a little flyer, good luck!

    After reading about David's CB160 build yesterday I decided I needed stop whining about my jammed shop and get busy making some room to bring this baby inside so we can get started.

    Whatever I could shuffle around to make room was going to give me a better spot than what David had to work with. (See post 240.) His build, and what he managed to pull off with his cramped work space was just the inspiration I needed.:bow Thanks again for that link, killfile!:thumb I'll look back for more build inspiration in there later on I'm sure.

    After quite a game of what I call the 'shed shxt shuffle' the little bike was ready to roll in into the house of pain...


    [​IMG]

    There she sits on the lift, snow flakes glistening under the fluorescents...


    [​IMG]

    Guess we got her in just in time.

    [​IMG]

    Interestingly enough, as I rolled it onto the lift the radio was blasting this out.:lol3

    After tinkering with another little project a bit we took a little time and gave it a once over. Inside of the tank isn't awful. 'Course, it's all relative to one I did a few years ago. A little bit ahead of myself but I started marking a few things that'll get removed from the frame when it's time. Took a few measurements of the frame for a seat, etc.

    Then it was time to head in. We'll start getting into it a bit deeper maybe tomorrow. See if we can't get it to fire.:evil

    And this changes my pace how?:D


    :lol3

    A little progress tonight...tried everything I could think of. No spark. Started shedding the pounds. More to go.

    [​IMG]

    Think I'm to the point of rewiring the ignition system just to try and get it to run. Probably go with a total loss system. Anyone care to share any knowledge on how to wire that up? Have some ideas based on a diagram or two in my manual but some experience would be appreciated.

    I case yer wondering the plug is in the exhaust on the outside chance I've imported some meece into the shop.

    BTW, pics working yet? How about previous posts?

    All pics working in all posts!

    I know Todd Henning Racing does a CB350 Stator for racing applications.

    If you run total loss, I wonder how long you can go before you run out of juice?

    I have run all weekend on 3A battery. Coils pull very little.

    If you don't want to splurge on some kindo mag set -up the total loss is the easy way, just have to haul a battery.
    I use a trailer plug , you know 4 prong dealy.
    Seperate the plug set. One half gets attached to the battery. If you're using a four prong set pick two wires and atatch to the posative terminal and the other two to the negative terminal.
    Match up the other side of the plug and run the color of wires you have on posative to the + terminal on the coil. The points wire goes on the _ terminal.
    The other two wires on this plug are your grounds. since you have two wires run them to different locations to ensure a good ground.


    Well there you go. You'll have to wire in a Kill Switch to pass tech. That just grounds the points side of the coil.

    The reason for the trailer plug is to connect and disconnect the juice from the coil. Your new key in other words. Never forget to unplug it after use , if left hooked up you could fry a coil.

    Thank you. Nice bikes, btw. Yours? Details?

    Splurging is out of the question right now. At least for a mag set up.:D Rear sets, OTOH...

    I'm thinking more in terms of basic wiring to see if I can't get this thing to fire up. Hate to waste a bunch of time trying to chase down all that factory wiring only to tear it off the bike in the end anyway.:baldy

    Thought a total loss system would be easiest at this point. Have also read a little bit about an 'energy transfer magneto' system over on Ohiocaferacers.com. To be honest I just quickly skimmed through it and saved the pdf file a while back so I'm not sure how applicable it will be.

    Looks like I'm going to have to find the latest set of rules eventually as I will have a few questions to answer. Kill switch may be the first. Basic toggle work or we getting into tethers?

    Got any more details? Less than 12V? Pics?

    I've read of systems using a few cells lasting longer than a race. Sounds like mykill has that covered and hopefully he'll give us more details. They'd bring multiple set ups and run them through the charger between heats.

    Pics? Still don't know what was up with it. Only thing I did different was I moved those pics from my email upload album to a new album which was created in the process. Even changed all the settings to allow access. The one I could see at least. Not sure it should matter as I've posted up pics before with no problems from an unlisted album.:confused

    In the end I created a new album and re-uploaded the pics the conventional way into it, then edited my posts.:baldy I guess it worked.:dunno


    The other side...
