    Welp, got bored and got out the saw, Sawed until the saw broke and well, this looks like it will work. I sorta want to find a disk brake front but for now this is what I got. I lost the title for the scooter in 2006 and then it broke and sat behind the shed. I blew up the T-dub in 2015 and never got around to fixing it. I sold the motor, swing arm and tire ages ago but got the rest of it still.

    So here's the plan! People make a Rukus with a 150cc GY6 right? I got as liquid cooled 250cc and a T-dub chassis. I plan to keep the T-dub seat, pegs, tank, front, switches and kickstand.

    From the China-scoot I got the rear frame, motor, drive, wheel, rear disk brake, radiator, engine harness and suspension.

    The idea is to trim all the little struts off the T-dub frame and weld it to the scoot's upper rear frame. Will have to brace the lower sections together and the radiator will wind up right in the middle with the battery in front of that behind the front wheel. Odd packaging but it will work out fine. The bike will be about 4" longer than the T-dub was originally.

    The scoot is a lot wider in the back but that's mostly to fit around the motor. It's just gonna have dat ass when it's done. Not that I'm worried, I mean, I do ride Superscoot.


    Anyways, here's the pics!

    And some of the T-dub. It's really stripped the rest is somewhere in a box.

    Lastly some mock-up. I was just eying the width and stuff here. Made a few marks but this is where the 25 year old saw broke and I stopped for the night.

    So far here is the BOM:

    New Carb boot $13.14

    New Carb $29.95

    New Bars $16.99

    New Grips $12.95

    Turn Signals $6.90

    Petcock for T-dub Tank $6.48

    A note on packaging. The radiator by default is mid-mounted in the scooter and will wind up where the motor was on the dirt bike. I'm a bit worried about not having enough weight in the front so putting the battery forward and using the fuel tank from the bike.

    Any input would be appreciated! I'm not looking to take a lot of time to build this, it's mostly because I can.

    I spent some more time and money on this. No new pics yet because there's just not much to see.

    I did buy some more junk from ebay:

    Headlight $15.99

    Headlight brackets $6.69

    Cheap H4 LEDs $12.95 for 2

    Cable pull brake lever because I broke the one off the T-dub $16.54

    Tail light for a trailer $7.99

    Random sealed lead acid battery $26.50

    New rear tire $56.56

    Diode $8.99

    I need to trim up the scooter rear frame and get it down to what just holds the motor and suspension. Need to clean off the rust and get it ready to weld. I also need to build a wooden jig to hold everything in alignment for welding. Don't need a dog legged bike!

    Anyways I seem to have lost the seat for the T-dub. Kinda random but does anyone have one in any condition? More concerned about the frame I can reupholster it. I do have a single saddle seat that's like a chopper style or whatever but I might also just make a seat. I don't know!


    I found a good wiring diagram that matches the scooter here.

    I am using mostly the TW200's controls, lights, and ignition switch. That all seems like it will work just fine. Trying to keep it simple as I can.

    Okay....
    This is going to be, uh, different.

    I look forward to seeing what you do with it.

    Although it seems like it will go the same way as the 2WD Fat Tire KLR I just looked at on here.

    And more. Again this is just tacked off my jig. I still need to cut all the braces to tack them in then I'm making a thing out of 80/20 to make sure it's aligned wheel to wheel before final weld. I laid the tank on it for effect, still not sure what to do for a seat, might even use the scooter seat since the frame for it is there. Dunno! Ideas?

    Pretty much.

    It does comfort me that the China scoot is going to its second-best use. Its highest and best use, of course, would be the shredder.

    The TW, I have more pity for. I know it's old and I know it was a box of parts. But 1500 miles? It was barely broken in...

    You have to watch investment, I get that.

    But the downside to the scoot format is the girly-mon step-through layout...you can get in and get rolling and not compromise yourself with your miniskirt. Never mind that the original Vespas were manual shift....they just don't have the image.

    You wanna have a he-man SADDLE on there, and a tank up in your face. Even if it's a dummy tank filled with Everclear for the party you're going to...

    Speaking of tanks. Is your China-scoot FI? Because then (as you know) you need the OEM fuel pump. Which would probably limit you to the OEM tank, or some sort of Frankenbike tank cobbled up from the bottom of the original.

    15,000 miless, hard miles. Even took it through Rocky Mountain National Park. Thing was on it's last legs when I got it, this is justice.

    China-scoot is carburetor, and I got a new one in the mail today. It will gravity feed just fine, the carb is low and back. I'm going to work on getting it running tomorrow after I brace the frame in.

    I ain't afraid of no scoot. Whatever this turns into it's going to get beat. I put 13,500 miles on the Superscoot last season alone. I also have the gold wing project in the works.

    Bonus images of T-dub's former life!

    Looking, again, at the butchered China scoot...looks like a Burgman. Was that the Burgman 400 clone you had?

    Tank and SRS and probably some others, sold them...for about seven years. I think there are a few still in inventory, five years old and unsold. They were based on the B400 design, with a Yamaha-designed engine, but didn't hold up.

    They all are to a point, My other scoot is actually a 2006 Burgman 400 with it's panties removed in a horrible accident. That is Superscoot linked above.

    This Roketa thing is just your average 250cc china scoot with a radio and junk. Same basic size and shape as my burgman but not nearly as nice of a frame. The tubes are huge! There was little storage under the seat too but that's mostly because the engine sits upright rather than laid on it's side like in the burgman.

    It's all working in favor of this project though!

    Speaking of links above there's a BOM, here's what was in the mailbox today!

    And did some welding and cutting. I went and got blades, disks, flaps and steel. Everything is now aligned and tacked up for final weld. Gonna pull the motor from the rest to do that. Also need to make a bolt in tray for the radiator and battery that goes where the engine used to be.

    So far it all fits! The left side brace sticks out to clear the motor junk on that side, right one is inside the frame. I need to make lots of gussets and plates to cover all the ends and junk. I might paint it bright blue.

    And more welding, cutting and grinding. I went through and made all the major braces, welded them end and made some of the ends nice. I made a lower brace and welded that in too before I put in the final bar later. I need to mount the rad and battery next and start wiring. I think I will wait till the sun's been down a while.

    Then I realized I ordered the wrong intake! So rather than delaying the project I dug out my turbo. Since the entire top end with piston and head is under $350 for this 2007 Roketa yy250r that's happening.

    There's plenty of room and it solves the rusty muffler problem too. Also this turd has external oil piping already, so easy!
