Most original thing on here *56k No No*

Well it's been a while since I posted some pics on this and it has changed drastically. The engine has been rebuilt for higher compression as well as being ported. The exhaust is also tuned now. The electronics have been rewired and the head has been polished and rebuilt.

Oh yeah fenders to keep the mud off and for winter some knobby tires. Come summer slicks will be going on it as well as a second gear for higher cruising speeds.

enjoy.


And for those unaware of the previous posts about this contraption it's a 60cc 2-Stroke engine mounted on a Cro-Moly MTB frame and currently reaches speeds around 40mph. A second gear and possibly an 80cc engine are in the works.


No it's not really safe. Needs better brakes, another thing that's in the works is a front disc.

Haha... That rocks....

minus the whole extremely unsafe could blow up your legs part, that is very cool

 

[Partizan]

can u do wheelies on that ?

 

[MasterShake]

how many ponies to the wheel?

Hahahaha, speed but at the risk of your balls Cool as hell though.

i have a few bikes that'd work GREAT with that thing on them. big disc brakes, 8" suspension travel, etc. how much did that setup run ya?

i too would like to know this...how quick can it get up and go?

total cost was about $160 though a lot of the pieces were custom machined for mounting.

No it doesn't do wheelies real well. 2-Stroke engines have a distinct power band that you tune for and I biased the tuning to mid-high rpm torque. The 80cc will more than likely be tuned for a wider band.

And there's no risk of it blowing up, it's a Yamaha designed engine from the 70's.

I've been thinking about how to mount it on a full suspension bike and beyond the bike needing to be a four link system like a specialized or something along those lines, it won't fit in the frame with many other designs. After that you'd just need a more advanced chain tensioner which could easily be adapted from a downhill racing tensioner.

Ebay is your friend for the engines and their kits. OR www.grubeeinc.com which sells much higher quality stuff.

looks good man, if i had more time on my hands i'd think about doing it

 

[DaGFTDOne]

I remember back when we had to peddle those things... I also remember my Mickey Mouse Tricycle, fun times, fun times

what you need is a bike with a concentric pivot- one that pivots around the bottom bracket, so the chainline stays constant. or, in a more perfect situation, you could use a single pivot frame and mount the engine on the swingarm, so it maintains constant chain tension.

I might bring it to the north east UCONN meet for some shits and giggles.

just saw this thread now i was lookin for pics of the rsx lol

ill sell you a brake, rotor, and wheel for $300 + ship if youre interested ... brake is a grimicea hydraulic, and the wheel is a mavic x-317 disc with the grimica hub and strong black spokes. I got a whole new setup for my new bike so this shits lying around.
