Put a real snowmobile secondary clutch on it and the right belt. The secondary is too small in diameter compared to a stock snowmobile one so that's killing your gearing and your belt.
I agree with Ryan Mallory except I would put a stiffer spring in the clutch so the rpm’s are slightly higher when the clutch engages. It should help get rid of that low end engine bog. Oh and definitely a new belt would do wonders too. And before you do all that gear changing you could reclock the secondary. So put the spring end into the next hole. That will give you more low and mid range power too.
Back in the day ('70's, lol) rather than changing the driver dogs, we would stiffen (or lighten for quicker top ends) the driven pully's spring. That way we would keep more pressure on the belt & give a bit more low end grunt. Have fun! Definitely love to see 2 strokes providing grins, like the old days! LOL! Stay safe, & thanks for the content, & chuckles !
It's a snowmobile engine but they're using the go-kart torque converter I believe. The snowmobile torque converter is much bigger and sturdier. You could be right but I assume go-karts go through mud and water pretty regularly.
This project is too cool. Love the fact that its a 2 stroke. Really makes this thing even cooler! Can’t wait for the next video on this. Thank you guys for bringing imagination back to TH-cam. You guys really make these projects your own. And with the new 3 man 3 motor mini bike build you guys are breaking new ground.
If you love 2 Strokes you will love my Yamaha Raptor 660R Yamaha 600 twin 2 stroke she's a Blast I picked up my Raptor Raptor for a steal it needed a Engine and we had a Yamaha 600 twin snowmobile engine laying around waiting to be put on something I Figured Being Yamaha Raptor 660R the Yamaha 600 twin would be perfect I'm going to have Stickers made that say 600R instead of 660R
Ide really enjoy a shop tour of all the projects. Just the glimpse we get during an episode makes me wonder what's still around and what projects we have all forgotten about.
Greetings from Bama y'all. Stumbled across this channel several years ago when my son and I happened across a couple of carts. Your 1st couple of episodes with the Killowat convinced me that it was the cart for me. We now have two of them going together a bit at a time. Can't even say how excited I am to see y'all revisiting this one.
I’d definitely get a tach on that if you’re gonna do more tuning that engine should turn around 7,000 RPM. The clutch is coming in way to low like Ike said and I’d definitely gear it down. To get more out of that motor I’d put dual 34 or 32mm Mikuni carbs on it.
Single carb is much easier to deal with and you don't need to sync with a second. They need to effectively double their gear ration to 10:1 or even 12:1 to be geared properly.
As a Canadian, for future and much loved by the way snow episodes, stud all 4 tires fellas! You'll be shocked with the difference. Thanks as always boys! Oh and by the way, sleds always have an extra belt stored. Certainly a weak point.
It cold and snowy here in S.E. Wisconsin. Its 8 degrees below zero today, time to get the snowmobile out and ride or go try some ice fishing soon. Enjoy the snow while you can and be safe, those injurys are going to catch up with you in a few years. Don't ask how I know. Lol. Great channel, one of my favorite!!!!
That 440 has the potential to rip hard 👍 I have a home made 540 sled powered buggy that hits speeds of 80 MPH and still has good bottom end. Keep playing with it you will get it there!
Good machine! The clutch you can take apart and drylube, and pre-tense it correctly. I think it would be better to set the rear dampers almost vertical in the chassis, not flat as it is now. Looking forward to next video.
Some tips on the Kawasaki 440 and belt drive. You can get a higher "Stall" speed on the clutch by very slightly loosening the belt. If you get it too loose, you'll get a very hard grab when it does catch. I'd also like to note that you are running an exposed belt in the snow. Wet belts slip. That will be made worse by gearing issues. The KZ 440 is one hell of an engine that can be tuned for much more than the stock 43 horsepower (We were able to get almost 60Hp from this engine in a Malibu Grand Prix "Virage" race car).
Not a KZ engine sir. Came out of a 70s Arctic Cat snowmobile. Most likey a Puma or EXT. totally different engine than what Kawasaki used in their bikes.
@@matthewbeito1431, My mistake on the nomenclature of the engine. My experience with them was as the powerplant in a Malibu Grand Prix "Virage" race car. Malibu Grand Prix used to be an arcade and go-kart amusement center at many locations across the US. They're mostly gone now, but the Virage race car was a 7/10 scale formula one car with a top speed in the area of 50-70mph -off- the track. I've spent a fair amount of time wrenching on them and tuning them when I was a mechanic at our local track, before it shut down. If you never saw Malibu Grand Prix, here's a video of an example: th-cam.com/video/YAEWjXwPnfs/w-d-xo.html
Suggestion: When you're rebuilding the suspension on that rig, make it wider for stability! (I'm sure forty dozen other people have said the same thing, of course)
Would be awsome to see some A Arm suspension built for this. Work out the kings with gearing / wider wheels and tires / belts / carb upgrade . Would be a little rocket contender for mini crosscart !
Just a thought: You guys are getting fast enough on this course to take downforce into consideration... you'll need large wing at these low speeds, but it would be extremely effective and not be too draggy, again because of the low speeds. You'd definitely pick up more traction than you would lose top end. Try adding some downforce to some of the projects to see if you can get better times.
@@michiganvapemafia595 Nah dude, surface area will make up for it easily. You don't need to be going anywhere near 100 mph to get good downforce. Try holding onto a piece of drywall in the bed of a pickup that's doing even 30. A bit of cheap sheet metal and some quick calculations (there's a formula) and they could keep the throttle buried for most of the course. Especially on the lighter projects that don't have too much inertia. Actually, there's a good project for them... build something ultralight with as much downforce as possible. I don't know if any of them can weld alu, but it's never too late to learn.
You are all on drugs. You don't run down force on an of road vehicle. You arent off roading in a Sprint car(or micro sprint). Oh wait! what about all those side by sides running around with giant wings on them? All the Baja trucks with giant wings on them? Oh right they don't exist.
@@jasonbirch1182 You don't run downforce on cars designed to jump. If you aren't jumping, downforce is a legitimate way to increase traction. The same rules apply... no amount of crying will change this fact. It's also a perfect project for this channel.
Just so you know older snow mobiles from the 90 and later all are set up with a high clutch engagement around 2 thousand 200 rpm. A lot of the slipping is from not having a cover to keep your belt dry they don’t like water.or ice so looks like you need a new belt. Recommend getting scotch bright pad to lightly polish your pulleys the belt rides on. Can’t wait to see what this project can really do once the bugs are resolved
couple of things, love the editing when yall were tooling on it in the beginning. real matter of fact. also, the project should be called the Bumblebee simply in the way it sounds and looks....plus you already have the yellow belt! keep it up, guys
FIY engine and jack shaft centre distance is critical on a snowmobile clutch for low gear! And proper high gear! Clutches need to be clean and free of dust and belt debris, both the primary and secondary clutches. It’s called a clutch service. In the snowmobile world. Pre season service. The more wear on the belt you loose low and high “gear”. P.S. that thing should Rooster-tail the tires with a 440
I've got a Kilowatt the same color and everything except mine has a Vegas Carts 460 block with billet everything internal and external. 780 drive and driven on the factory motor/jackshaft plate (the only thing I had to do is move the plate to the right about 3 inches and then replaced the factory jackshaft with a new hardened steel one that ended up being about 3 inches longer. The best upgrade imo is the front and rear hydraulic disc brakes!
maybe y'all should hook up with rather be welding for one of his 2 speed jackshafts, have a current gearing setup for high end speed, then add a reduction for everything else, so you've got trails, then you have a sand gear for busco beach, glad to see this running again, and i know y'all will turn it into a real ripper, you guys have really stepped up your game and came a long way from the early days of "tinkering in the garage", stay safe out there
Snowmobiles have a drive unit that has 2 different size sprockets that reduces the ratio. Going straight to a pulley is about 25-30 percent too tall. Get the ratio right and it will easily do 70 and still have great low range
This thing is a couple of steps away from rocking your leaderboard; convert the machine to have a wider track width so it doesn’t wanna roll over as easy
I think your right like Pontiac Grand Prix wider is better. Grind hard plumbing co. Did it on colonel senders they said it turned Easier and felt way better. They widened it three inches.
With a snowmobile engine setup, you want around 10-12:1 gearing to get the most out of it, including longer belt life. It was setup to move a snowmobile with somewhere around 2:1 gearing.
Your biggest problem with the belt slipping is the belt is wet, soaked would be more appropriate, let the belt dry and watch it fly. If you build some sort of cover or wheel well it would greatly help if not fix your problem. Love the vids and keep up the good work!
I have a suggestion for you guys pertaining to the snowmobile I think that you should add a body kit to it to protect and keep the wind off you for the winter
Omg!! You guys should definitely do a go cart/snowmobile hybrid!!! Using a track for propulsion!!!that would be RAD!!!! Front half go cart back half snowmobile!!!
i'm always impressed when i see anything you guys build actually works. the level of booty fab is second to none. stack some more washers and another zip tie on it
It would probably help to put a cover around the drive and driven to keep water and sand off. That will cause it to slip as well.
The 2 stroke Murray is BACK! This engine is supposed to make 38hp... Now we just need it to get to the wheels!
Whats up with this spam ^^^....the way ike said choke me....lol its almost to natural isnt it lmao
You guys need to get a set of wheel studs for this reason
How about a go kart on tracks?
Or a change ski set up for the Front for those biannual snows lol
Put a real snowmobile secondary clutch on it and the right belt. The secondary is too small in diameter compared to a stock snowmobile one so that's killing your gearing and your belt.
I love the Vador breathing from Charles behind the camera during "were about to do some hotlaps" portion!.... this thing rips!!!!!
These belts do not like water, it needs a cover to protect it from water or snow…. Good job guys, can’t wait to see the upgrades
I agree, if the belt gets wet it slips. HAd this problem in a Polaris quad.
I agree with Ryan Mallory except I would put a stiffer spring in the clutch so the rpm’s are slightly higher when the clutch engages. It should help get rid of that low end engine bog.

@Natalia Santiago hey China your about to be BANNED
I also think the snow is wetting the belt contributing to the slip.
i agree, making something to protect it from the elements would be good

The Murray has always been one of favorite build's, been watching since it's first appearance and have enjoyed every episode.

They're using a garbage CVT. First step should be a good one with good belt.
2 stroke content is definitely top two in my favorite video collection for cars and cameras. Just saying!!!
2stroke POWER.... great video... enjoyed the lil snowman...
Ike in his element. That looks like so much fun.
I love that you guys stayed true to your roots!
My motor! Glad to see it running again!
It's good to see this project revisited.. I love those snowmobile engines..
As a Canadian, for future and much loved by the way snow episodes, stud all 4 tires fellas! You'll be shocked with the difference. Thanks as always boys!
Oh and by the way, sleds always have an extra belt stored. Certainly a weak point.
When I saw the weather report the last two weeks for the east coast I knew y'all would be doing something in the snow. Good job boys
THANKS GO POWERSPORTS!!!!- the good Ole days.
"So we both get to go ring the bell!" - Man I really like Charles hes a cool cat
Long travel suspension would make that thing beastly

Just realized yall hit a million subs. Congrats guys, you boys deserve it. Hoping to start recording and posting. Yall are a big influence of mine.
@Natalia Santiago your about to be banned
Love the 2 stroke stuff. This thing is crying out for some tuning and a big power pipe would be mental 👊👊👊🙏
I was gonna suggest doing a wide-track suspension change but it sounds like all sorts of fun stuff is coming for this beast. Can't wait!
Still waiting to see the green race kart finished...
Nice to see 2 stroke getting love.
Love that Murray, glad to see it again. And you guys should definitely do more 2-stroke stuff!
Give that thing some long travel suspension to keep it from being so tippy! Awesome build!
Wow 2160p cool!
The snow makes this thing all the more hilarious!
Super cool cart. I love sled engines on go carts Just rad guys.
Longer stiffer shocks will be a nice addition but what you really need is a Bump Stop or something to keep up off carb
That snowmobile powered kart is awesome guys !
With that belt slip it sounds like you’re making fire wood. Love the build !
I can't wait to see more of this kart! It's probably my second favorite of all the OG karts
awesome build !!!!!!!!!!
That 440 has the potential to rip hard 👍 I have a home made 540 sled powered buggy that hits speeds of 80 MPH and still has good bottom end. Keep playing with it you will get it there!
The belt is probably slipping because it’s wet from the tires kicking snow all over it
Wow! You guys got snow! Cool video!
Front camber looks pretty wild. Could be more than just the snow affecting the handling.
Good machine! The clutch you can take apart and drylube, and pre-tense it correctly. I think it would be better to set the rear dampers almost vertical in the chassis, not flat as it is now. Looking forward to next video.

Man y’all gotta get that thing dialed and send it for real! It looks like so much fun!

hello from North Carolina!!! so cool to hear that you guys from this beautiful home state!!
Front tires look like they have a severe camber issue.put some bigger tires on the front fix the camber and belt issues and let it rip. Cool project.

nothing beats the smell of 2 stroke in the morning
6:46 Charles: "I love the smell of 2stroke in the morning.....smells like...power".
Nice ideas for the Murray
Can't wait for this rebuild. When you do front and rear suspension that is when you need to widen the front end and the rear probably at least 2 in
If you add some width to that unit it will feel way safer to ride when it is greasy. I would say 15 to 20 inches wider 🤟🏻🇺🇸
Your biggest problem with the belt slipping is the belt is wet, soaked would be more appropriate, let the belt dry and watch it fly. If you build some sort of cover or wheel well it would greatly help if not fix your problem. Love the vids and keep up the good work!

Omg!! You guys should definitely do a go cart/snowmobile hybrid!!! Using a track for propulsion!!!that would be RAD!!!! Front half go cart back half snowmobile!!!
The track looks good with snow on it
Can’t wait to possibly see this wider with bigger front wheels
