    Nice! A neighborhood kid got one just like that in '72, brand new. Gawd I was so jealous!

    These are great little bikes.

    Here is my '71 TC90 that I bought in 2009 for $150. It only showed 831 miles, but had sat for a very long time. The inside of the tank was rusty, the carb was plugged up, and lots of pitted chrome, but decent shape otherwise. I'm guessing it was used for a couple years when new, and then put away in a garage. The plan was to make a fun little off-roader with it for my kids (and me).

    [​IMG]100_9430 by speedfourjoe, on Flickr

    I did some work on it in 2011-2012. I rebuilt the forks and painted the frame. The engine just needed some clean-up and new seals. Unfortunately with the focus on some other projects it ended up sitting again.

    In 2016 I finally made up my mind to get back on it until it was done.

    [​IMG]100_9919 by speedfourjoe, on Flickr

    And here it is done. It's all stock, other than stripping the street parts from it and the fenders. The front is a Preston Petty Mini Muder, and for the rear I modified the original fender. I liked the '73 style green stripe, so that's how I painted it. It runs beautifully, and is super fun to ride. It'll happily putt around like a trials bike, but open it up and it'll move right along. It has also already been the first time riding a real motorcycle for several people. It's the sort of bike that if someone is at the house and has never ridden a motorcycle and is curious what it's like, a quick ten minute lesson and they're rolling right along. Anyway, if you've got one of these sitting around, it is well worth it to get it going again, even if it takes awhile.

    It’s beautiful! So, mine is still sitting in dry storage, and waiting until I get to Alaska this summer and pick up my other parts. Carb, clutch cable, and etc should be in my moms garage from my parts one. Maybe I’ll have it running by July. Thanks for the pictures!

    One cool mod you can do to the ts/tc 90 is to install the piston from the 100cc factory hop up kit. A simple bore job,a piston and rings and off you go.

    I haven’t gone to Alaska yet to get my spare parts ... but, today I put some chainsaw gas in a spray bottle and started the Tc90 without the carb on it! Ran good! Let it run for a minute, but didn’t want to overdo it or let it get lean and have overheating problems. Probably the first time it’s been started for 20 years.

    My 71 TC90 back in the day. First trophy ever racing MX. Also had the lime green 72 TC90. Then went to a 72 TS125 and then a 74 TM125, before going to the 74 CR125.

    I finally saved up and found a pristine gyt kit down pipe. Really woke it up on top, compared to the Hooker. Hit a rock first ride and put a big dent in it. Oh well.

    2nd trophy ever racing mx in the TC90. I paid $125 for the bike from the local Suzuki dealer, with grass cutting money.
    Had more competition in mx then scrambles. I had miles of hard trails I could ride from my door, so naturally I could ride that stuff better at the time. Soon after I dedicated myself to mx only.

    Note the bumper hitches on the 65 F100. Had the odd ball 352ci engine. 3 on the column. No seat belts, since they were an option in 65. Lost dad 3 yrs ago. Miss you dad.

    Lost my dad in 2008. I know the feeling. I started riding in 8th grade. A couple of girls in the town (sisters) had that Suzuki 90 (or maybe it was an 80) I showed a few pages back. They wanted 25$ for it. My dad had railed against the idea of me on a motorcycle. But when I told him 25$, he was like, 25$? Does it run? And yes I’d did. So he let me buy it. He and I got it running well. I headed out, rounded essentially the first corner, behind a big building, on a gravel road,and wiped out hard. Tore up my left knee, my pants, etc. I knew if I went limping back I was done riding motorcycles. I rode that thing all day long, came home, threw away the ruined pants, and hid the injury for several weeks till I healed. Never looked back! Absolutely hooked on motorcycles. Had about 28 of them since.

    Dad had many too, including a big Suzuki GS1000 that he and mom rode back and forth from Alaska on, to Minnesota and other stateside places.
    The pictures are: high school era motorcycle collection, a Tc90 with a Honda engine after a 60 mile ride to a dredge, and me crossing a stream on sisters xr100 on that same ride.

    Ok, will have a carb in hand next week some time. Plus, a few other parts. Will keep the thread posted as the final touches are applied. I’m gonna try to get the bike titled too, as soon as I prove to myself it’s running well.

    Dang it. Arrived in Alaska, and I have the speedometer and a few other pieces, but no carburetor. My extra carb was for an 1983 XT200. May have to buy from eBay unless someone here could help me out?
    Also, the Suzuki RV90 carb Chinese knock offs on eBay seem similar, but are too small probably? Any other bikes with the same carb? It’s a very strange built in clamp intake manifold side, and is not very common, evidently.

    Meanwhile, in Alaska we rode the tar out of the frankenbike ts90. My Son on the ts90 and my street legal ttr225. Sister on her xr100.
