In this video we roll out our most recent find, a 2001 Kawasaki Ninja 250 that we are going to be transplanting into a Manco Deuce buggy with semi-independent rear suspension. After a little bit of wiring work and carb tuning we were able to get the bike running good! After it was running we basically just had to remove it in order for it to be a crate engine ready to drop into our motorcycle powered go kart!
Thanks for watching and be sure to subscribe to see this thing get dropped into a custom buggy!

Say hello to our newest Craigslist finds this is a Kawasaki Ninja 250r 2001 and we paid $ 200. For this thing it is an absolute hoopty. Every single fairing is held on only by zip ties and as this car like fuel filter, it has a Grom headlight taped to it. The good news is the engine.

Every single component is there, I'm pretty sure it still has the OEM filter. Everything has like everything, has basically the original stamps on it and stuff. So no one's tampered with this bike, other than zip tying other fairings on it. So the owner claims it runs and drives, but we haven't heard it fire yet so the first thing we're gon na do is tear this thing apart, getting a gas tank on here that actually holds gas and then see what happens.

The previous owner had a lot of problem with leaking fuel and they had this giant car filter on it, but it makes it easy for us, since it's not bolted down at all. Everything just looks clean underneath this not too bad. Definitely a diamond in the rough like we got the OEM filter, some stuff, some computer, the guy did say the computer was bad on it. So that's probably, though, with the one you replace, and they want to get me back in good yeah.

I think I think the next step is. We should check the oil and stuff and then Lexus zip-tie a predator tank right. There see what happens it's a little on button for this battery is actually kind of nice. This guy's a lot of voltmeter inside right.

Now. It's beeping at us and it is low voltage, yeah she's angry, we'll charge it up yeah, I think we'll. Just anybody put it on a jump start and we can try the guy said it does not crank over, because this solenoid is bad. This guy right here we have all the ones of these, but maybe it's just not getting voltage for the fuses out yeah.

I remember what we said earlier, this bike being super hack, we're not helping yeah we're not any better than them. This thing looks so stolen. Hopefully not hold it with your knees, all right, we were sick of messing with wiring, so I am aboard, so we just want to jump to start the starter with a which is the jumper box and see if it runs. Let me suspect the engine is flooded.

I don't know because it doesn't turn over very well. It makes a lot of compression, though that's good. This is starters, not just whirl and look crazy. We got the air box out and we're looking at the carbs, and this one on the right is just pouring out of the top right there.

So it looks like maybe the float or something. Maybe you have a problem with our focusing like that. So what we're gon na do is get this off. You know on the bench we're gon na order, a rebuild kit, so we can make sure everything's running right and then for now we'll just try new start, Hey, look.

We got a nice suit and need some card work, but yeah we're gon na rebuild the car, get right back out here. Okay, so I got the bowls off these carbs and everything actually looks really clean. This gasket looks really good. This one looks a little bit crusty and that's the one that was leaking.
So if my float adjustment doesn't work, I think I just need to replace these two gaskets. It won't be good, but stock kawasaki claims you need 17 millimeters of basically as soon as the needle and seat goes in just the spring, barely touches. It needs to be 17 millimeters from here to the edge of the float. This one was perfect.

This one was a one millimeter too big, 18. I just bent it a little bit so now we're perfectly inspect, but I don't think that was our issue. So I'm a little bit confused of why so much gas was pouring out of this one, but I'm gon na reap it. The Bulls on that make sure everything's super clean and I'm gon na rehook it to the carbons, see what happens.

Baxlo height so should be all ready to go. We're gon na hook it up to jumpstart and see if it runs but hey it runs guys, runs pretty good. Okay, so I've been editing this video at school and those of you don't know we kind of record a lot of our videos during the summer and upload them throughout school year, because we're all college students but anyways. I realized that there wasn't a lot of closure on the fact of like how we got it running right and stuff and basically it's just a constant velocity carburetor.

So that means there's kind of a mechanical butterfly valve. That's connected directly to a throttle. Cable, as you can see how it's turning, but then there's a vacuum diaphragm that raises and lowers a slide. So imagine you have your butterfly valve and then the slide more air in the butterfly valve equals more vacuum, which raises and lowers your slide and essentially the slide part wasn't working.

So we can be at full throttle here, but the side wasn't open, so it wouldn't. Let enough air in if that makes sense, but basically the fix for that was all we had to do is put the air box on cuz. I'm pretty sure it's just how it was engineered to have a certain amount of suction coming in. So, basically, that's that let's get back to the vid okay, so it really doesn't take much like looking at this thing to realize that it's probably not a good idea to ride it on any public road or even like get Auto Bella motors running I mean we Definitely could do it, but the motor is just like it doesn't require tuning.

The carpet need to be saying stuff like that. It's like it runs good and stuff, but like it's still having, although like butterfly your shoes and all of that, so I think what we're gon na do now is completely change the direction of this video. My original intent was, we were going to get it running enough to where we could actually drive it and rip it around a little bit, but I mean this thing is super sketchy, so what we're gon na do is we're gon na strip that start stripping. This thing down we're taking the engine in sprocket and rear brake off for the cart itself, and then I think so, instead of like the second half of this video being driving the Ninja, it's going to be making the mouse to put it on our Deuce crawler.
250 ninja boogie all right, so this motorcycles career, I guess time to disassemble it. I think it's further better, though I do kind of some mechanical sympathy. For this thing, it's not like we're in a fight we're still gon na rip it on the buggy, but I guess it's time to tear it apart see this tire is all we're taking for now, because we're just going straight to go power, sports and we're gon Na try to see if we can find some hubs that the idea is we're gon na use the stock sprocket on either the jack shaft of the axle and the stock rear brake. I think that'll give us some really good braking power.

So a huge transformation is a bike here kind of just to the parting it out phase everything's going off of it. Well, basically, everything that we're gon na need for a go-kart is off of it. So now I have literally one more engine bowl to take out and we should be a lift to frame up from the engine. There's only three engine mounts on this thing, which makes it pretty easy $ 200 crate engine is removed.

Don't have use maybe like 7 to predators, ok, so now that the engine is completely off the bike and basically it's like our it's on a little crate engine right now ready to go in our Manko deuce buggy build those are going to be the next upcoming Episodes, but this thing seems to be a really good runner. I don't think we're gon na have any issues with it. The name of the game here is gon na be torque, so we're gon na gear it down a lot and then hopefully our rpms can be able to help us get a pretty good top speed. But we really want this thing to have a ton of torque and be a lot of fun to shift the gears and stuff so yeah, thanks for watching make sure to check out the deuce build videos coming up soon.

There's gon na be really cool. We're doing a lot of different suspension components on that and make sure to check out our merch. Thank you. Go Powersports and we'll catch you next time.

    I was wondering if the newer exhaust system fit on the older bikes and now I see it does, the fairings not so much.

  2. Avataaar/Circle Created with python_avatars Richard Tomeo says:

    hi do you still have the tail /seat piece and do you want to sell it. thanks

    Hello, i want to fit ninja 300 air-filter box on ninja 250r 2010 model is it possible do they both bike carry same filter box?

    I love your unit of measurement "two predators". Nice.

  5. Avataaar/Circle Created with python_avatars Liten Fara says:

    You should really get a better dyno. The last one looked so flimsy.

  6. Avataaar/Circle Created with python_avatars JohnSmith FakeName says:

    I have seen buggies powered by Ninja 250's. They are fast, and sound awesome.

  7. Avataaar/Circle Created with python_avatars Ran Dom says:

    Hey for some reason your videos don't pop up in my feed anymore

  8. Avataaar/Circle Created with python_avatars Dave’s Boredom Busters says:

    Throw those stupid cv carbs in the trash and slap some mikunis on it. You’ll thank me later.

    G'day Guy's hey I'm in the process of doing a buggy build myself I got a Applestone buggy with no motor , and bought a Yamaha xj 600 motor to put in it , all up it has cost $550.00 , $ 400.00 for the buggy & $150.00 for the motor, hopefully it won't need too much more to spend on it . Being a 4cyl it should be easy to get off the mark and have good torque right through the rev range , on the clutch , I'm not using a pedal but a clutch leaver on the gear shift stick , then a brake pedal & a foot throttle . I will have to put some kind of governer on it when my kid's are driving it , until they get used to the speed .
    Good luck with your build , you's young guy's do a great job on your builds that I've seen so far . Until the next vid , bye . Mal.

    Everyone is pulling bike engines for powerwheels…. Can you put a powerwheels motor on the bike? Yeah, screw them! Better yet, turn the bike into a 10 speed with a derail-er, chain and peddles.

  11. Avataaar/Circle Created with python_avatars Mad-Duk Machine Werkes says:

    If it had a flooding carb, then it had Gas in the oil. Obviously, change that.
    Also – Kawasaki are notorious for smashing the rod bearings when you crank it over when engine has liquid locked, watch & listen for future signs of rod failure – bearings are cheap as are gaskets, but if it launches a rod thru the front of the case, you wont find another engine that complete without other major problems for only $200…………

    Why dont u build bikes anymore i wanna see bikes not go karts

  13. Avataaar/Circle Created with python_avatars Randy Hertzberg says:

    I put a ninja on an all alum home built chassis , changed drive to #428 chain ( got engine sprocket from Sprocket Specialists , they match up trans spline , chain size and tooth number), good luck getting axle sprockets , American chain sizes are not the same as metric, split metric sprockets are not available for 1.25 axles. ( I had a machine shop EDM the bore for me) Having a lot of trouble with the CV carbs & pod or a K&N filter to run right , love to see how you do the carbs . my engine is 2004 , same gen as yours
    I used rear master cylinder and caliper from bike with Go Power rotor & hub. Also robbed the harness , gutted it to only use what I needed to run the ign , start & cooling circuits. Hand clutch on steering wheel , shifter kart style shifter , foot rear brakes… wiring will be a challenge , there is a 100 ohm resister in the ign circuit to deter theft , and the safety switches have to bypassed . (they all go thru the brain box and there is not an aftermarket replacement)

  14. Avataaar/Circle Created with python_avatars Nick Davis says:

    You should put a 420 on the bike frame and that'll be awesome, also can I get a shout out for this great idea???? 🤔

  15. Avataaar/Circle Created with python_avatars Bart Mcalister says:

    Those motors are amazing with the extremely high rpm they rev it should RIP on a kart. I know the 250r I had was the most fun in a small cc motor

  16. Avataaar/Circle Created with python_avatars discontinuuity says:

    What does semi-independent mean? Like a torsion beam rear end?

  17. Avataaar/Circle Created with python_avatars Remnant D says:

    Good donor, it'll need some lower gearing. A 250 twin that redlines at 14k isn't going to be big on torque unless its screaming. Should be a cool project. 👍👍

  18. Avataaar/Circle Created with python_avatars TJ Ferguson says:

    Going on a buggy with low gearing for torque, the stock clutch will slip. It's the same friction plates that the zx1000 uses. The weak point are the springs. Upgrade to some barnett springs for 85-89 zx600. Part # 501-50-05055. You'll have alot better engagement and be able to get the power where you want it.

  19. Avataaar/Circle Created with python_avatars DAT Blue Husky says:

    that bike will never be legal lol so its good thing you guys gonna use the power plant

  20. Avataaar/Circle Created with python_avatars Build Break Repeat says:

    If y’all wana see what the kart this is going in looks like be sure to check out our instagram @build.break.repeat for a sneak peek!

    build two predator 670's inline to make a 1340cc v4 to use for a 1/4 mile drag project
