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?

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

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.

Hey! What city are you in? send me an email @ 3dconceptsutah@gmail.com

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.

@3dconceptsofutah757

5 ай бұрын

Thanks for sharing your ideas! Yes it has the stock jetting rated for about 6k elevation. The high elevation jet seemed too lean.

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.
