In this video the rotary go kart gets everything it needs to have a rolling chassis, this includes mounting and welding up locations for the rear axle, as well as extending the steering and tie rods to accommodate for the wider frame. It was a lot of welding and fabrication but we are very happy with the final result and stance of the kart! The motor is off of a 1975 Hercules W2000 ultra rare rotary motorcycle, 30hp 6 speed.
Stay tuned for the next episode where we get everything this motor needs to run mounted to the frame and ready to go!

Welcome back to the road rebuild, we've got a lot done, the last episode. What are we doing that ages? Okay, so today we're gon na finish the rest of the frame mount the axle the tires, all the steering, basically just get a rolling chassis. Let's get started back bars ready for the go power, sport seat, locked up my place, and then we got these original mounting. Tabs they're.

Just gon na go right here, yeah, so we're gon na get them welded up a minute, pay up the frame and finalize our seat mounts for the front. I bet this up and it basically the exact same dimensions as the other side, so we're going to measure it to make it equal notch. This cut this one here and put in a ninety bar and then we will have a symmetrical frame again. We got the seat all mocked up and I mean I'm the tallest out of all of us.

I've got plenty of legroom arm room. We won't be burning ourselves, the engine I mean everything will fit really nicely. So next step is rent. The rotary mounted up.

No one will be able to go power sports you get tires and axle and all that type of stuff. So we linked in the steering wheel about four inches, and then we flipped this little block around. So it's it's a little lower and we got our plug, which is again what fits in here and as well as up. We just got back from go power sports with the steering all done and everything on the rotary cart.

So you can see that pile over there we got a bunch of stuff, we've got six and a half inch tires from the front and eight and a half for the rear. We got a huge one-inch axle. Shaft we're gon na run four bearings on it. That way, we don't have any twisting or anything like that.

We got some. We got an awesome brake rotor. We got some fuel lines, some 50 chains, some sprockets. So that's basically everything we need to get this thing, a roller and then other than finishing touches stuff.

She's gon na be pretty close to driving by the end of this episode got some six and a half inch go power sports rims, which we then put six inch tires for a little bit of stretch and we just mocked it up and full lock. I mean we got a little bit space right there, so our tires are perfect and powersports hubs on, and then we use the original spacers. So we got it spaced out a good bit and time for the rims, hey guys. They look so huge on camera have heavily Matthew, so sadly we couldn't reuse the anodized aluminum ones, but good passports hooked us up with some really nice ones, which look pretty good and something I was worried about is that the frames still kind of you know like The frames flex on racing carts for better handling, so this frame just by lengthening, does still flex.

So everything seems to be good. We got our massive 54 inch axle here and now it's time to start mocking up where the rear axles going to be part of an issue we're gon na have with this. Is the chain there's no way to move the engine forward or backwards, and once we weld the hangers in there's, not gon na be a way to move the axle forward or backwards so usually have one shot of this to get the chain tight and be able To like run different chains in the future, if we ever break one or something like that, so the plan of attack is we're gon na cut all of this out, except for this front plate right here that way, we have something to square up these against. So we can get it basically perfect dimensions with the front.
So I guess we'll do that grind it down, get the two on first and then we can start making our support brackets to do the other ones and then we'll have a sprocket on this side and then we'll do the other, bearing on the other side and Put the brake in between so we welded our sprocket to the hub. They didn't have a hub that fit this bracket. Size is kind of a weird size, so we kind of shave down the inside a little bit to fit really snugly and well did it both sides. So I think the metal should break before this thing.

Does this looks so freakin sick? I think we picked the perfect offset for tires and stuff right now. The rims are a little bit more out just because we Center they don't both sides of the axle, but now we need to do is going to determine how far back or excellently to go with the chain. Okay, so now we're going to get the chain on and cut it to length what we think is going to work alright, yeah. It actually needs to go in a little bit.

Okay, so that about wraps up our axle here, at least for getting it laid out and centered up. I think what we'll do is I'll put like one more tack on each hanger, we'll put the wheels on it and then we can set it down and take a good look at it. And if that all looks good, we'll put it back up here and then we can start working on our second set of bearing hangers. We totally take that wheel off the ground way.

This way, you know turning this way, we're like pretty much off the ground. Oh we're doing our second set of axial bearing hangers, so the idea is we're just gon na have a bar like just like this and then brace it here. So we'll just cut this one right to length here so far. This is looking really good.

We have bear and support right on either side of the sprocket and then what we'll be able to do is we'll be able to get the tire right up against, basically like it's really close to the bearing that way. We have support right next to where the traction is gon na be so. Basically, what we're going to do is we're going to try to mirror this as exactly as possible, but instead of the sprocket in the middle, we're gon na have a break, so we just cut this bar. It's an inch longer than this one to be symmetrical with that side, and this will lock in our break, and so we just got to clean it up and weld it and we'll have another crossbar and that'll be it.

So we got this other bar in and we boxed it in. We can't have a bar back here because of how big the rotor is, but it's time to finally weld on our fourth bearing and then we're gon na be able to disassemble this whole axle weld up. Our bearings reassemble. Excellent! Get this thing on the ground for hopefully the last time, all right guys.
This thing is shaping up to be a sweet cart. Thank you. Go Powersports for all the parts of tires. The rims everything we've been using has been from go power, sports we're getting pretty close to 100k.

So we'd really appreciate it. If you liked this video and give us the sub and we've got shirts too, we've got some merch. So if you want to check that out, there'll be a link in the description. This is actually our rotor and the logo that was on the original motorcycle and then check out our instagram at build break.

Repeat: let's try and grow that one a little bit and we'll catch you next time.

    WHOA! It looks like a jet turbine on the side of your cart! Thats beast AF!!!

  2. Avataaar/Circle Created with python_avatars J hill says:

    What happens when the chain stretches with all that power . Might need to add a tensioner to take out any slack.

  3. Avataaar/Circle Created with python_avatars XX nรผ XX says:

    hey, what's the reason to make the engine not down as possible?

  4. Avataaar/Circle Created with python_avatars andy b says:

    Great job guys . You should use ear protectors though . Tinnitus is not nice .

  5. Avataaar/Circle Created with python_avatars George Lalama says:

    Wow! You guys have come a long way in a short span of time since I've commented on your last build. Keep up the good work!

  6. Avataaar/Circle Created with python_avatars TravisFabel says:

    probably too late now, but if you took the rear mount of the engine and made it an adjustable height so it would pivot across the front mounts, you would then be able to adjust the chain tension without moving the engine forward and backwards.

  7. Avataaar/Circle Created with python_avatars Donald McCombs says:

    There is a company in China that makes little turbos that would be fun to put on that. That's kind of all I can tell you because I forgot all the details.

  8. Avataaar/Circle Created with python_avatars Gage Stewart says:

    That engine is going to shear the key on the axle shaft. XD should of thought of a chain tension system as well juuussst in case.

  9. Avataaar/Circle Created with python_avatars Liam mcclelland says:

    Did you guys make sure the alignment was correct and do gokarts need to be aligned?

  10. Avataaar/Circle Created with python_avatars ษ‘สŸpสœษ‘ ษฑษ‘ัสœษชะธษ‘ says:

    You guys have a bump steering issue going on there. It's likely because of how much you widened the frame, but there are ways of fixing it.

  11. Avataaar/Circle Created with python_avatars OnE says:

    I made something very simular back in the day and a simple fix for the chain is a idler sprocket hinged on a tight spring

  12. Avataaar/Circle Created with python_avatars Mitchell Nunn says:

    Why does ya boi have frosted tips. Tell him to lose the frosted tips. Not a fan on the frosted tips

  13. Avataaar/Circle Created with python_avatars xLittleBoy- says:

    I'd rather own a rotary shifter kart than any other shifter kart with a motor you think it'd be possible to put a 1 rotor 13b engine on a shifter kart?

  14. Avataaar/Circle Created with python_avatars Julio Collins says:

    That rear sprocket is extremely small. What made you decide to go with that gear ratio? you could easily weld a chain tensioner to help with and slack

  15. Avataaar/Circle Created with python_avatars David Borysowski says:

    Chain tensioner will help you adjust chain "snuggly" lol
    Axle sprocket way too small. You plan doing 300mph?

  16. Avataaar/Circle Created with python_avatars Joe cook says:

    Just wondering if the 1:1 sprocket ratio might be too high? What was the ratio on the bike it was in originally?

  17. Avataaar/Circle Created with python_avatars Hola! ThatBoyDakota says:

    Subbed and Liked for rotary power ๐Ÿ™‚ hype to see where this goes boys

  18. Avataaar/Circle Created with python_avatars Taylor Madden says:

    Did you guys get the turbo friendly version of the ecotrons kit. You know it needs the bigger injector and the 2.5 bar map sensor. If not you might have some tuning problems with the turbo and just that a small map sensor and injector.

  19. Avataaar/Circle Created with python_avatars RainyDayGarage says:

    Question, I don't know if you guys or anyone else here can answer this. I have a SACHS KM48 160cc single rotor. I am trying to convert it from magneto spark to electric spark. Can anybody help me?

  20. Avataaar/Circle Created with python_avatars Matthew Mazzella says:

    Little too wide but awesome. Would have mounted the engine a little lower myself. Keep it up.

  21. Avataaar/Circle Created with python_avatars carol Kampstra says:

    if your worried about the chain get a chain tensioner and put it on the bottom

  22. Avataaar/Circle Created with python_avatars Michael Neal says:

    if you're worried about the chain getting loose you should add a chain tensioner

  23. Avataaar/Circle Created with python_avatars Alexandertheaverage says:

    Im doin a similar build with my bridgeported sachs km24 with keihin carb putting it on a tonykart race chassis. Will be a lot lighter and wont have to mod the frame as no gearbox just a race clutch. Will handle mint. Drifts on! Good work tho guys, im definitely watchin this space
