    This is the sad story of a doomed project. The “bike”, a little Honda Z50 Minitrail hardtail, was originally purchased by a friend who never did anything with it. He then sold it to another friend who quickly realized that it was a money pit and bought another Z50. He had me fix the second one so his grandkids could ride it.
    Then one day he just showed up at my house with this little guy. Well, actually, a bunch of parts that resembled a bike.

    A quick look told me that the project is not really viable. It would cost way more to fix it properly than it would be worth in the end. It had such lovely features as this:

    Or that:

    Or even this:

    It’s also missing the seat, handlebars, and the muffler is a goner...

    So I pretty much decided to abandon the project altogether. But then I ran into a little issue:

    4F080C51-6679-4373-8535-2EB1E75AC57F.jpeg

    That’s the original tank, with the original paint and badges, it’s still holding gas and is not horrible on the inside. It does have scrapes and bruises but is mostly sound.
    The engine is also not locked and seems to have decent compression.

    So I kinda have to try fixing it. I can’t let it go, I am an idiot...

    Step one, cleaning the carb. Before and after and rebuild kit in the mail.

    I love my little ultrasonic cleaner.

    The muffler:

    The good news is that most of the JIS screws are untouched.

    But some seals are leaking like the kickstarter shaft seal:

    4FC2E026-AA1F-4280-A4AC-A537792BC405.jpeg

    And someone made sure the clutch adjustment would not be messed with :

    02E6AF3B-D95F-4AFE-9BD0-21007349ADBE.jpeg

    I adjusted the valves (exhaust was a bit tight) and changed the oil. I then sprayed a little bit of brake cleaner in the intake and it started right up, of course it only ran for a couple of seconds but, it ran...

    Wanted/needed list:
    - complete seat
    - exhaust (at least muffler)
    - handlebars
    - peg brackets and pegs
    - tires and tubes
    - more stuff that I am forgetting right now...

    I already blew the budget and I haven’t bought anything yet.

    That's ok, I only spent $1000 on my "$500" project. The big stuff like engine work I estimated correctly, but all the little stuff to make it work nice is what killed me. Cables, new tires, chain sprockets, seat foam and cover, air box, handle bars.......But it was fun and rewarding.

    it's amazing how that can happen. Don't get me started on my $143 Triumph I bought... Lets say we exceeded the acquisition cost a few times

    Yep, I figured so far, buying all chinesium stuff:
    - complete seat $100
    - exhaust (at least muffler) $200
    - handlebars $100
    - peg brackets and pegs $40
    - tires and tubes $80
    - more stuff that I am forgetting right now... $200

    So, $720, and the bike will still look like crap and be missing tail light, rear fender, etc.

    Well, you're into it now. You have to finish it. And photo it...

    Small update and not many pictures. Mostly because my hands were covered in 45 year old grease and I didn’t feel like taking my gloves off to take pictures...

    I “rebuilt” the front end. What I mean by that is that I picked through two sets of crappy forks for the least worser parts.
    The bad ones were really bad:

    1D0AEB3F-24AD-4043-BB0D-F6811B213BCC.jpeg

    Now, the “good” ones were not much better but were at least straight and with minimal rust. I cleaned all the old grease and re-applied some new. I also installed the first chinese part, two viton o-rings from Harbor Freight to replace the “fork seals” that were beyond saving.

    Took me about 45 minutes just to clean the lower fork caps threads and get them to screw in all the way...

    The nice surprise was the steering head bearings. Once the dried out grease was cleaned out they were actually in really good shape. I re-lubed and re-assembled everything without issues.

    Sorry for the crappy pics.

    I also found out that I am missing a seal and a spacer for the front wheel. Hopefully I can make something up at no cost.

    Another minor update, mostly just to make me feel better about myself...

    I cleaned the brakes front and rear. Disassembled, cleaned, lubed the pivot points with aluminum anti seize, and put it all back together.

    Here are a couple before/during/after pics:

    Again, crappy pics, it’s snowing and I don’t have enough light inside.

    Then I tackled a project that I have been avoiding: the wheels.

    I read the horror stories and I knew the tires were still original, or close to it. The tubes also still held air by some miracle, so I considered just putting them back on just to restart the bike. But, in the end, I knew that they needed to be taken apart and repainted at some point and that I would never do it if I had to take them off the bike.

    So, I gave it a try, and after about only 30 minutes:

    2F01110E-2F89-484B-8B0A-C885BA1D1B62.jpeg

    It wasn’t too bad, all the hardware is in great shape, there is obviously rust but they will be useable after a good scraping and a coat of paint.

    Here’s the worst of the rust:

    9BDC85DD-21B0-49CE-8E72-9C239EAE1CC5.jpeg

    And to give you an idea of the condition of the tires:

    C3AEE7B7-35F4-4EF0-B16F-C1B2FFEA07A1.jpeg

    Now to order new tires and tubes...

    I am looking for handlebars, pegs, seat...
    I am on a couple of Facebook groups but no luck so far. Just looking for useable parts, nothing pristine. Just in case you need to clean out your garage.

    Treat the rust with some Ospho or other rust treatment if you can't bead blast them before you paint them.

    The wheels look good! Not a rust hole to be seen. They came off the tires easy I suppose?

    Define “easily”. I did break a sweat but there was no blood...

    Snow update: got rid of the rust using a wire wheel mounted to my drill and a flap wheel on my angle grinder. Then a good cleaning with brake cleaner and a nice thick coat of Rustoleom using a disposable $.99, Harbor Freight paint brush (to keep with the Chinese theme). Hard to take a picture, and as exciting as... watching paint dry.
