hi.why do you need more speed?increase the speed, the thrust will decrease. on my 2*2 motorcycle, the maximum speed is 45 km per hour.in the mud or in the snow, you won't go at this speed)🤝
@@3dconceptsofutah757 do you think with the some mods to the 212 it could make it up to 45? I tinker with mini bikes all the time so I would imagine if it's doable on a Coleman it's doable on a rokon
The Rokon has a lot of drag with the front wheel drive mechanism so it would take a lot of power but maybe. The bike is also really unstable at about 35 so I don't know if you would want that@@tylersowell7460
The only one that I ever saw had a commonly used 2 cycle motor probably around 80 cc. Low to midrange power, no high end porting I have the same motor in My antique Terrel chainsaw
Great idea and custom fabrication work! You could patent an entire engine swap setup for Rokons and sell them. I’m sure a lot of people who love these things would love to install all the components you put on your bike too! Great idea!
For those talking about they thought rokons were faster than this? This is the off road edition. What he has basically done here is turned this into the on road version. The ranger. That one is set up to be faster. About 37 mph. And thats about as fast as you want to be on one.
Between the foggy mountain view, and the super clean Rokon build, you are living another mans DREAM! beautiful! ❤ Great content, and earned a sub, bc we would sure like to see what you get up to next! Attention to detail is top notch! Keep up the great work!
The rokon transmission has three gears. If you could only get it up to 20 miles an hour, you probably only had it in second dear. It's supposed to go up to 35
I rode it quite a bit to familiarize myself with it before the engine swap. Not to say there wasn't something wrong with it but it was definitely in third gear. There's no question about that. There may be some drag in the transmission that's limiting the top speed though.
Awesome upgrade !! If I buy another one, I want you to do the emgine upgrade on it !! If I get another one it will be the, I believe the 1969-ish Rokon Trail Breaker . The big Yellow One .
@@MasterSumaiI live in Pa and just bought mine. I’ve be looking at them for 25 years, never thought I’d own one. I bought a 2018 that the man sold me for $2500! It looked pretty narly, but it was only dirt and grease, with weird home made rack on the back that I removed. Turns out after just cleaning it up? It’s like new, nubs still on the tires , it’s in mint condition, he said it had low miles. Trail Breaker hunter addition.
I have seen mod kits for the Kohler engine: billet flywheels and cams. Remove the governor and if (I say if) it can rev to 5000 is should go close to 50mph. Can 3D concepts try this?
That is possible but it seemed to rev to it's limit. The way the throttle is connected with a little ferrule screwed into the cable is pretty sketchy for a production machine! Thanks for the comment!
Thank you! So your's has a shifter now? I really think this should have just had a normal motorcycle engine to start with! Do you have a video? Cheers!
If you have ever ridding a real bike and a rokon you probably know the chassis and lack of suspension and brakes and crazy torque steer are the first limitations Offroad. More power will just brake the little 1/4" roll pins that already brake stock.
Yes it is a way awkward machine and I made sure my client knew things might break with more power but he wanted to do it anyway ;-D It's not really a raging monster even with twice the power. I'd personally rather have a WR450 but there is a bike for every person. I think of these things like a crawler on 2 wheels.
The OEM jetting in your Rokon may be set up for Sea Level. At that elevation in Utah (as you stated in reply in the comment section), I would guess your carburetor needed a change in jetting to compensate for the elevation of being around 1 mile high in altitude. This may also be the case with your swapped in engine too. Also, lube those front drive chains, that’s got to be a lot of friction at top speed.
That's an idea swapping engines however also on TH-cam their's a Russian version of 2wd but the clocked that tractor going 46mph top speed. Just that I point that out. I like the mods.
I live in Utah as well. Awesome work on that engine swap. I just bought an 86 Rokon that has a Predator 224 but the exhaust needs to redone. Let me know if you'd be interested in helping me with that.
can you still throw it down into the river and float across to the other side and then ... will it restart ... thats what i would like to know , please ?
Mine has the same Tillotson 212 electric start, but I took a different route for more speed. The Rokon DOT Ranger version has smaller(faster) wheel drive gears, I got them from Rokon but they are a common "industrial" type gear. To increase top end drive RPM I installed a larger Comet Series 40c Magnum clutch (209709a), and a (209133a) driven clutch. The 40c clutch has adjustable weights for tuning the response, a wider stronger belt, and with the 209133a 2nd clutch provides an even lower bottom ratio AND a considerably higher high-end ratio. Basically the clutch provides increased RPM for speed instead of spinning the engine faster. The engine: I wanted low RPM torque to preserve the Rokon's ultra slow crawl ability. Stock cam, add 2nd charging coil to double output, very minor porting to clean up/smooth, Tillotson TCT or TFB mechanical fuel injection carb(smooth running low end). I used a 1 1/8 (cheap "performance") exhaust pipe, but I might try the stock one (and tct carb) to see if it works better at lower RPM.
@@3dconceptsofutah757 I see the older ROKONS had a West Bend 2 stroke .. It was a detuned Go Cart Engine.. Later purchased by Chrysler Industrial .. called a Bee now days.. It would be fun to install a two stroke .. Better yet a Honda with a 4 speed trans and centrifugal clutch ..

makes me wonder about the new engine? Kohler is a reliable engine not much can kill them save for no engine oil... Wonder if the Kohler can be tweeked for an upgrade.
How did he ruin it? Those things won't go fast enough to be able to take your feet off the ground damn sure won't climb a hill in anything over first gear

Should you swap engines on a Rokon? Probably not! But it's more fun doing stuff that shouldn't be done don't you think?

I own a 1967 2-stroke. It goes a whopping 21 mph in 3rd gear. Would love to do an engine swap just for the noise reduction.

Hi! I got your email. I'll write back
Me too
Awesome video cool, swap, beautiful mountains. What area is that?

@@3dconceptsofutah757 just stretch the frame a little

@@3dconceptsofutah757 thank you for taking the time to answer me and nice job on the rokon.
That's sick! Very well done swap!
Thanks man!!
is it still amphibious?
Same as stock, you can't submerge the intake
@@3dconceptsofutah757 could you add a small outboard, or mod it to have a propeler, bit like the shaman or argo...
40 miles per hour would have been the icing on the cake.
Maybe gearing up would be good because it has more torque to pull a higher ratio now. First gear wood still be low enough to climb anything
So you call it a gutless wonder and then immediately show it being anything but.
Plenty of torque in low gear but very little horsepower for get up and go ;-D
Put a different main drive sprocket on...
Definitely could. It has a good balance of torque and speed now. The owner was really happy with it when he rode it
