I appreciate all the feedback (specifically about the expansion chamber)! That's why I love youtube! I will put it back on ASAP just have to figure out how/where. In the mean time, submit a video/picture of your projects so I can put them in the next video! E-mail in the description
Yeah you REALLY need a proper exhaust on a 2-stroke engine. Check out Colin Furze's channel for an how-to on making these using a pressure washer :) ----> Pretty much welding two flat and thin plates together at the edges and expand it with high pressure water ! Nice project :) Exemple : ua-cam.com/video/bCsg5pQimWI/v-deo.html
Lol...back pressure. Tell that to ALL the guys running open headers on their HIGHLY tuned drag cars. Whadda they know other than going stright? 🤣 2 strokes need a saxaphone aka tuned pipe or expansion chamber to rebound the pulses that spit unburned fuel out back into the exhaust port.. Its intrinsic to the design of having no valves.
aksu neither two strokes or four strokes require back pressure. Stop perpetuating myths lol. The motor is running fine, it sounds like it was tuned for one forsure, but that can all be fixed with carb work. The expansion chamber harnesses exhaust pulses and sound waves, nothing to do with bAcK pReSsUrE.
Well No but it dose take way the power band keep mind that many of older 50's thru 80's only had straight exhaust but plug end cap with smaller size like 1/2" to 1" pipe output should help be able to gain some that back with out being a crazy motor
@@SHSPVR none of that made sense. This is a 2 stroke engine, the expansion chamber cones reflect and focus sound waves in the exhaust back towards the cylinder to keep the fuel/air mixture from escaping into the exhaust at certain RPM and being wasted. That's why 2 stroke dirt bikes and quads seemingly take off like a rocket when you reach a certain RPM and "get on the pipe". Power valves or exhaust valves in the cylinder can modify this behavior. The cones in an expansion chamber are tuned to a particular cylinder because of the "port timing". I quoted key words for you to google.
@@charlesgunzelman3323 Maybe you should try look at early 70's motorcycle like a Suzuki TS250, T250 or T-250 II hell even the old Kawasaki widowmaker and puppy one wicked ass bike that had little to no expansion chamber hell even chain saw, week eater have no expansion chamber wake up buddy, port timing should ready be max base on it bore and stroke.
NIce job! I'm glad you had fun laughing your ass off going down the road at 65mph...I think I saw you pass Mad Max on the shoulder. Remember these skills; you will need them following the apocalypse.
@@OliverMotorized make sure you keep the same dimensions of the pipe, if you make a pie cut to move the chamber somewhere, only cut half the pipe, add the piece back to the other side so you don't change any lengths, only angles.
@@OliverMotorized we put a 440 Kawasaki from snowmobile on 3 wheeler.... WARNING!!! When you put expansion chamber on from original exhaust...2 stage clutch WILL take the handle bars from your hand. ADD A KILL SWITCH so it will not leave you sitting on your butt too far away from the bike. I got the T-shirt on that ride!
Just when I think you've done it all...nope! Insanely cool build! Thank you for all your effort and time that you put into providing us with awesome content.
What we have here is Mad Max type builder, that plays some of the best Blues I've heard since I watched another of your videos.. Keep em both rolling, as I appreciate an inventive warped young mind, as much as the Blues your providing along with it..
i use to love to build stuff out of junk.i built a 70 mph lawn boy riding mower that would mow grass. i have built a 65 mph electric bicycle it would go faster but the spokes kelp coming loose. i put a SBC on a 1953 ferguson tractor. that i still have. one day i'm going to get rid of it or maybe get it running again. the only trouble with building stuff out of junk for me is i'm 3 days older than dirt and can't really do it anymore. and if they had a love button i would have clicked it for sure
Fun Fact - I owned an 1980 Artic Cat Panther. The thing was an absolute MONSTER for being 22 yrs old. It ran perfect! Bought it for $600 in 2002 and sold for $600 in 2006. Old and slower than the newer sleds (every other sled that is haha), but an absolutely reliable machine! Large times were had with that snowmobile :) Also I'd recommend some safety squints! Just lookin out for ya. Cheers-
09:05 just finished hacking up a perfectly tuned exhaust... no amount of carburetor tuning is gonna make this run well now... weld the tuned exhaust back on if you wanna make it run right.
Chalk the front, Put the back wheel up in the air and watch what your clutches are doing whilst someone runs that rpm up. Crouch down and watch closely what is happening by your leg, body, life. That thing is Badass. You are a mad scientist my man.
We built go-carts and pulling tractors with snowmobile engines, clutch drives and solid axles. The acceleration was insane. The craziest one was a pulling tractor with a 650 Polaris Wildcat and a 670 Ski-Doo Rotax both running on straight alcohol with twin expansion chambers for each. That tractor was violent when you left the line. We did tractor pulls all over Ct. Great bike build !!
God do I love this channel!! He builds awesome rigs, and listens to his comments' advice!! Ps. Weld that expansion chamber back on!!! You'll feel that powerband kick in 10x harder than before.
Arctic cats are bad ass! My brother had a old one and it was tuned up. That thing flew! I swear it was 0-60 in just 2 seconds it was SCARY FAST! I remeber driving it and anything under 20 it was almost stalling out. It was happiest going full throttle lol miss the good ol days
Nice I my first impression is he's gonna get hurt but yah know what u doing it just don't trust those 2strokes their crazy responsive and fast. Wicked run tho Be blessed Jah Rastafari Selassie I Jah
You are a genius my young friend. It takes a genius to be able to build a motorcycle out of virtually nothing as you do. I would rather ride your motorcycle than a brand new one off a showroom floor. I know your videos don't show the countless hours you spend figuring things out, but you are a self taught genuine fabricator, builder and master mechanic. Thanks for taking the time to film your projects. Just watching your test ride take me back to my younger days, I just wish I had been half as smart as you are.
Everybody telling him that the engine wont run without the expansion chamber lol. Youre right and wrong. They obviously make a great improvement if made and tuned for the engine, but the original way two strokes were piped was a straight pipe, a really long one that was cut down little by little untill the engine ran best. So yes, the expansion chamber would help give back some of that great two stroke SKKKRT, but it is not 100% needed.
Great job Ollie. I like to see the young go at it on their own. It shows you have initiative and are willing to work for what you want. THOSE ARE ATRIBUTES THAT WILL HELP MAKE YOU SUCCESSFUL IN WHATEVER YOU CHOOSE TO DO.
Sweet! I would have thought it would take off faster, maybe better with the carb adjustment. Hey 65mph on Frankenstein bike is pretty good, little scary too! If you need more snowmobiles there are plenty down here in Utah. Not too far of a drive from Oregon.
I was like 2000. This was a cool video to watch. Seeing everything repurposed and pulled from other things as opposed to another Harbor Freight engine swap in a factory minimize or dine buggy etc... It was nice seeing something built from literally junk and or scrap yard type salvage. It might not win any beauty pageants but it's functional. Keep doing your thing man. I am subscribing!
Might want to increase the oil delivery to help her cool as these Fanners were designed to be run in 40 degree & lower temperatures . Great build ! Love it !
Just as I thought in the comments, never modify the exhaust, that tune would be ok with an exhaust, exhaust is everything on a 2 stroke 440 , cool build
You could just put the expansion chamber back on at the bend there, section the in/out a bit with some sheet metal to get it pointing back the right way. Sweet idea though and really good first test.
You NEED the stock exhaust with the expansion chamber or a custom expansion chamber pipe. You probably lost 1/3 of the power by removing it and all the torque :/
You might explore your options on the drive pulley as well. Different springs and weights in the drive pulley will give you different engagement, or Stall, speeds on the engine revs. A snowmobile has a rather heavy drive train that needs a lot to get it moving, compared to a motorcycle. Getting the clutch engaged and driving you at lower rpms, and thus getting you in higher ratios at lower rpms might increase your speed range.
Cool bike, you are throwing hp away when you cut the exhaust. But that has already been covered. Those big Cats were a blast to drive! I have a 303 Wankie panther cat, I need to use it! Thanks for sharing, Bob Ordewald Staunton Va
The rest of the expansion chamber exhaust is important, really important. Putting it all in as designed will let that thing really scream. You can hear the effect from the exhaust is missing. You won't believe the difference. Cheers. Well now that the other comments are visible, first time they weren't, I guess just consider mine as a vote for the expansion chamber.
That was totally radical. Shows a lot of ingenuity on making the brackets and such. I agree with Aidan, expansion chamber would definitely give you a few more ponies. I used to race snowmobiles in Michigan, and it was a lot of fun in my younger days. WTG Oliver.
I am 76 years old. Reminds me when I was young like you. Have fun. Brakes are essential. No brakes you dead. Isn’t it great to take what you have laying around and make something good. With high gas prices. How about a street legal diesel motorcycle. Cheap to run. Great fuel mileage. Roadstar.

@@asfodhell Best is to use original. If chamber is not right size it wont work eather.
Use the stock exaust the expansion chamber is a game changer

Definitely it needs the back pressure to reach its max power

poor performance, way too noisy, looks like crap ... i love it

Awsome, I looooove two strokes! Cannot wait to see it run with the expansion chamber installed!
I love the style of your filming. It's both enjoyable to watch and very artistic.

Sounds like my take me to the hospital RD350 74 Yamaha Nice Job
You sir are a madman....I like your idea and the way you think...
before you mess with the carb, reweld the original silencer (muffler) back together, trial run, then fix the carb if needed
So raw. I love it . You do need the stock exhaust pipe. 2 strokes are partly tuned with the exhaust pipe
James Jenkins yeah I’ll throw it back on for sure!
To bad those to stroke don't last long that motor design for cold climate 🤔 hope it last . Have fun.
Snowmobile is a lot heavier work for engine than bike.

Sounds like the motorcycles from Excitebike
I love the sound of these two strokes and wondered myself awhile ago what a bike would sound like with one
Ditch the oil tank and do premix for a slightly cleaner look or a split tank like a Harley.
Good idea, It's also just in the way too!
That's a great idea.
Great music too.

This is really cool !! Also kinda ironic. back in '93 I put a Honda 550 motorcycle engine in a rupp snowmobile. check it out Randy S Coolbaugh on FB.
Absolutely awesome bike!! Personally, I would've made an expansion chamber, and routed the exaust on the other side of the bike. Sick build!!
Cool build!!! Mad Max look out! ...And def fix that exhaust, it'll run even better!!!
