This video starts our racing mini bike build series. What we do in this video is pick up this motovox mini bike that has already been swapped with a 212cc Predator Motor, but not just any 212, this bike has a tillotson 212 that is completely ready to rip!
What we do in this video is pick up the mini bike and begin the metal work and frame additions. We use sheet metal and eastwood's punch and die flares to add some cool additions to the frame along with a torque converter conversion and spun aluminum gas tank addition.

What's up guys in this video, we do metalwork to the racing minibus and make it come to life. Some of y'all may be wondering where part three of the robbery video is, and basically the rotary, has had some serious issues. We only made 30 psi of compression when we rebuilt it the first time. This is all the second time we've torn apart, but basically, I think we're having compression leakage out of this this mating surface here.

So, if y'all can help us by putting down in the comments like what y'all think like we were thinking, maybe like copper spray like these on head gaskets, something like that and then like law y'all commented about maybe using glass and sandpaper to like sand this down. Without like something like some very fine grit sandpaper that way, you don't have to go to a machine shop, but all we do is just kind of take down some of the like higher surfaces, because there are some like little little imperfections that you feel this is Kind of a bad one right here, yeah, so anything like that's really gon na affect us on these videos. Thank you. Guys, hang in there we're working on this rotary really hard, but hope you enjoyed this video yeah I've.

Yet, to run this thing, my dad actually picked it up for me, while I was at college, I just met modems with cash. Thank you, daya, let's see if she starts up I'll, see you over grunting this way, hi guys so we're trying to beat the rain here. We have like a 15-minute window. Basically, like all the videos from now on, are basically just like when we're back from college.

For a weekend because it's like a three-hour drive back from a.m. so basically we have two days to complete, builds so and then we got to go back to school, taking exams and stuff, but we are here and it is not pouring rain. So let's try this minibike, so we can take it apart. We go enter Tillotson little monster moto season.

She did a little baby. Honestly, it's pretty light. Yeah brakes are good too. It's tough, dank also.

We got a motorcycle jacket, so it's got padding and everything. So we actually be kind of safe. We were elements and jeans like we're kind of getting our stuff together because, honestly, like we should set a good example for safety. I know it's hard because it's like safety kind of sucks and it's boring, but I mean you can do more fun stuff when you're alive and not have broken bones in the hospital and stuff.

So it being said, let's try not to break some bones on this. Mini bike that should have an 80 cc motor on - oh, my god, the things oh, it's fast, y'all Jason to be the driver for the mini-vac drinks, better yup and he crashed hit the curb you all right. Bro that was a proper dump. Is it broken? They handle, I don't keep put it upright you all right, though.

Oh no, that's how you do a front fork. Do we need a new front fork or we need to straighten the front fork. I explained Issa so, as you can see, there is a good layer of water on the ground, so I was going kind of fast. I got on the brakes in a puddle over there.
Just locked up tried to steer couldn't so I just jumped over the handlebars took no impact laying it on my feet, so that's good at least bus maneuver. By the way, this um the front fork is definitely messed up other than that it should be okay, Oh they're, so wet. That's bad all right time to assess the damage and show us the parts yeah sprocket sprocket adapter, we're converting it to 420 chain, which is gold here, Philip flywheel billet rod, flat side, mikuni premium, torque converter flat top plate with a gas tank on top tires suck. Like that we crash this thing, so I think the preliminary focus of this episode is going to be doing all the metalwork stone all right.

So there goes, there's still have to throw everything attached, but I mean this thing's in really good condition. It's really nice. Having this pretty much brand-new performance and for hey this is so light, so now we will begin the metalwork face. So, basically wanting to do you kind of have this like dummy engine here, so we can do mock ups and stuff I'll, probably just pull it's working where their backing plate to this.

So we can just figure out. What's going on all right, so we've got ta. Have a pretty good idea, let's see me going on here. Basically, I think, what's gon na look really cool dimple guy, like it's from Eastwood, so we'll probably fill in a square on that sheet metal panel here sheet metal pan on this triangle sheet metal panel.

Here that sheet metal panel on this panel - and you like three dimple - dies here, a big dip with I that two small dip with us here, two small ones here and then the same on this side and that's gon na look awesome! Okay, let's clean up! That's not too bad, so we'll probably end up putting in a little bar right in there. Yeah just ran that off and then a bar there and perfect okay. So you did some clearances and now we have plenty of room. Well, not plenty already, but we don't room so now.

What I'll do is I'll mark where we can weld it? A little nosh bar right there we're making progress okay. So we got this kind of janky setup of like a bunch of different clamps and zip ties. Little pieces a wooden stuff but found or tried to get it so that everything was kind of held in place held straight and then it'd be bending. Both bars at the same rate so looks like it's working just gon na make sure it's not oh it is.

It's kinking a little bit, so we got ta readjust point. It's lost earlier now so promising that it's getting better so weights me when we did here is I used part of one of the pieces we cut out and just it is a nice little bench here. It kind of matches some of the cemetery going on so then I'll give it some room for the torque converter and give us give us the structural rigidity I have so now for that. Alright, guys so update time, it's a new day and here's the motive oz.
I just I just kind of doing some experimental stuff and I cut out a little triangle to go along here and that's going to look really good. The side plate fully welded on - and I also kind of marked out some holes where I think dimple dies would look pretty good. We might also just do I'm gon na wait for Jason to get here soon inside, but we talked about these earlier. These little triangle, justice will go up.

Our experts made specifically for the monster moto, so I'm gon na will them all. I have to change over to flux core, because I ran on a welding gas and it's Saturday and all the places we get around here close it is, I don't will of a flux, port and forever pretty happy with other stuff. That's a lot more spatter than I'm used to doing stuff like a wire wheel, that I'll clean up really nice to be so dang good, whoa, all right, so I loved it. Others are kind of working here doing a ton of metal work, but I think we're.

Finally, wrapping it up now we move on to more of the fun stuff. You know what it works, pretty fun. It just gets a little repetitive. We got this song, these gussets on the front piece, and I have the two circles on there got this side on.

Just will on the scope are squares. Kickstand I've actually never used on this before they're, actually pretty sweet and it's easy to get it to tuck up really nice and see it kind of sticks out so you'll be able to get your like that. That's yeah, yeah, yeah and then also up here these first three whole gussets, along with they use two pieces of angle iron and bridge them in the center. So I think this looks pretty good.

It's kind of hard to make it sleep it out for this, because it just sticks out so much. You can see no power strips because it comes to the same clamps. I also threw a 90 on this place as possible. All right so just cut this on the bandsaw, because she's hot in the last video we kind of crashed this thing and broke the front forks.

So basically, what we're doing is we've got this piece of steel, so it have like some notches and stuff, and this it's basically like a half box steel, and this will slide right over here, we'll weld all along here and then what we can do is hammer This these down in and weld in there, so it's kind of triangulated and we'll just pull out all this. Well, all right guys. So, as you can see you up here, I already dimpled I've a lot of these front holes and that looks really good. So now, basically, all I need to do on this Eastwood dimple.

That set is basically just drill, a half inch hole and then put in the tool, and then the tool does all the work so put in our nipple guy too, with an 18 millimeter socket. Okay, yeah that looks Wow. I can't wait to. I came into this bike.

Okay, so we got all four of these real, simple things done. These things are amazing, they're. So simple: there we go oh yeah like so we have a farm horse and we have these three gussets here which are kind of the same size of these and Apple. What's going on here, yeah, I think now.
What we'll do is I wan na so basically before we paint it, I want to do a basic mock-up with the Tillotson to the top plate on it and then the gas tank. That way, we make sure everything fits so get that installed right now, alright guys so here it all is all mocked up. I mean I don't really need to speak. For this thing, it looks really really good.

I'm super excited, though everything's kind of mismatched colors. Well, it's all of this is white and like these, like gold, this gold hardware, it kind of sticks out and like the blue racing engine - and it has a martini paint scheme, feel like insane and this front, like dimple dies, kind of always stand out. We also like to beef this up a lot, so I'll have to worry about that, breaking it off so cool, oh also, the top place did not work just because of how tight everything - and that is in here - it's an ABC Z, monster, moto, Frank anyways. So I mean we've barely and fit with this 90-degree petcock in there.

So that's all good! It doesn't really need a top plate, just cleans up a little bit, but it'll be fine without it. Alright guys, thanks for watching this thing really turned out great. All these little details and dimpled eyes and little body panel type things we did are really gon na make. This thing look amazing in the next episode when we paint it and do the martini library and touch up everything and make it look perfect yeah.

So, thank you guys for watching be sure to check out go power sports. All these parts enter get yourself a Tillotson racing engine from them all the links will be in the description. See you next time.

    how did you get the 212 in the frame? any mods to make it fit ?

  2. Avataaar/Circle Created with python_avatars Krisztian4u says:

    Awesome video! Thank You for sharing!
    May I ask, does the torque converter fit right on Tillotson 212 ? I ordered an engine and I already have the Comet Tav2 torque converter. Thank You!

  3. Avataaar/Circle Created with python_avatars Corey Barrick says:

    My forks did the same thing I fliped them around made it look lime a chopper

  4. Avataaar/Circle Created with python_avatars Johnnie Walner says:

    What exhaust is that ? I need one for a predator for the exact frame

  5. Avataaar/Circle Created with python_avatars 1digitalwatcher says:

    Will the frame bolts of the tilotson line up with a baja racer frame ?

  6. Avataaar/Circle Created with python_avatars handyhippie65 says:

    so, you're studying engineering, right? you already have a jump start, and you know you enjoy it. if you can get paid for doing what you love, you'll never work a day in your life.

  7. Avataaar/Circle Created with python_avatars TinksTheMetal G says:

    Any issues..with fitting the stock Tillitson motor? Into Monster Moto frame?

  8. Avataaar/Circle Created with python_avatars Joris Vos says:

    Rotaries usually make less compression than normal engines, right? Not sure but thaught i read that somewhere.

  9. Avataaar/Circle Created with python_avatars Scott Hite says:

    You can't sand the face on the Wankel with a sanding block. It needs a large flat abrasive surface, and then you can move the part to surface it

  10. Avataaar/Circle Created with python_avatars zach hodg says:

    My buddy crashed the same mini bike into a town garbage pale doing 70 ripped it right out of the ground front wheel was touching the left foot pedal

  11. Avataaar/Circle Created with python_avatars Allan Holloway says:

    I'd recommend using Loctite Gasket maker 518 with Loctite Primer SF 7387 we use it in the marine business to seal blocks together I've also used it on my four wheeler engine it works amazing

  12. Avataaar/Circle Created with python_avatars Thor555555 says:

    greatings from germany, i like your rotary projekt, best for it would be to resurface/flatgrind all surfaces and the piston by maschine. i know, easy to say as a proffesional maschine grinder but maybe you can find a workshop which can do that, excite him for the project and offer some publicity for him on your channel. maybe it wouldn´t cost as much as expected.

  13. Avataaar/Circle Created with python_avatars Philip Rowney says:

    Dudes, get a nice sheet of [ float ] glass [ will be perfectly flat ] and wet, add fine Emory powder [ or carborundum/diamonddust ] and 'lap' in figure of 8 motion until happy it all touches. [ sic: lapping bench ]

    PS I am a Software Engineer, you know, like Elon Musk, only 14 months older ;0)
    Coding a 13, mechanic'ing at 18, hacking everything for the last 30 years =]8¬_D

    I thought it was a bad idea to split a clean engine in the first place, I see you guys and 'rather B welding' making the same mistakes every time by ripping stuff to bits. [ SMH ]

  14. Avataaar/Circle Created with python_avatars BryDuhBikeGuy says:

    Awesome again guys!Had to watch your builds,Flu vs You,is always going to Your vids !Thanks guys.I can't wait to rip too.

  15. Avataaar/Circle Created with python_avatars Watch me do me says:

    ive broken many bones on race cars and bikes lol ankle, tib, fib, femur and pelvic bone. i have 5 rods and 20 screws trust me safety first ive learned that lesson the hard way lol

  16. Avataaar/Circle Created with python_avatars Gunny Fine Productions says:

    I got the minibike suspension forks that are monster moto and they rock, would recommend them for sure

  17. Avataaar/Circle Created with python_avatars Jon Lasaga says:

    I would suggest not sanding on that plate if you take off more material you might lower compression even more because of the way the surface connects. You could try dunking the engine in oil and pumping air through it to see where you are losing compression since you will be able to see the air escape.

  18. Avataaar/Circle Created with python_avatars Some Biker Maniac says:

    Talks about safety sucks. Immitidaly crashes. Lol nice go safety lol

  19. Avataaar/Circle Created with python_avatars Dan Hambrick says:

    I knew somebody was going to crash when I saw how wet the parking lot was….

  20. Avataaar/Circle Created with python_avatars Ben Pennington says:

    nice job on mini bike cool lil project dimple plates are awsome…. P.S you should try get some gas and run standard mig wire much ezer and cleaner

  21. Avataaar/Circle Created with python_avatars nigel morgans says:

    Hi all just a thought how come there was no gaskets when you put the rotary back together metal on metal just not a good idea…??.

  22. Avataaar/Circle Created with python_avatars takman03 says:

    Judges scores for Jason’s dismount 10. 9.5, 10, 9.5, 10 and 8. What the heck Chinese judge. Glad you’re ok. The bike looks awesome. I’m still waiting for the hovercraft build.

  23. Avataaar/Circle Created with python_avatars gage anderson says:

    I did the same thing on mine just bend it back and weld supports it works great now

  24. Avataaar/Circle Created with python_avatars DaShlook says:

    Can always get gasket paper and make your own gasket. They sell it in different thicknesses as well as different material. The have a paper gasket as well as a cork gasket.

  25. Avataaar/Circle Created with python_avatars mike eger says:

    Also what you did to the bike make it way stronger as far as ridgidity. That thing will be super strong as far as stress to the frame!! Awesome
