Thread: 2-Stroketastic!!!

At high school there was kid who had an"American pie" moment with a Swedish exchange student...poor guy saw out his days at high school with the nickname "2-stroke"... sorry funny story that always comes to mind if someone says "2-stroke".

Anyway, I've always had an affinity for proper gas engine 2-stroke engines. My parents weren't rich, so my love affair with these engines wasn't realised until I had an income of my own.

My first purchase was a MX bike. 250cc of craziness!

Then a 12A rotary RX7... technically a "2-stroke". Cheap speed, fun times! And although I'm more into my V8's now, I'm not afraid to admit the odd rotary catches my attention, and makes me smile.

Next was a Kt100 gokart. You'd wonder how a 100cc engine could produce so much power...actually I still do wonder how - absolutely incredible!

Then came gopeds. I have 5 goped sports, all in various extremes from near stock to insanity! This is my dream build...this bad boy will be nuttier than squirrel shit! I just finished the motor today, its a hybrid...I won't bore you with details, but lets just say it will be fast





The expansion chamber is a work of art!

Anyway, the above is the result of the dangers of the internet and a paypal account... let this be a warning!

Oh and while my wife and three kids are away on school holidays...hell yes this gives me the right to build a gas engine on the kitchen table!

Started off as an already high spec little engine at 22.5cc.

It's a hybrid, meaning the bottom end is a zenoah 230rc, the cylinder is a Chinese clone that's had the head machined off. The cylinder head had 4 transfer ports...these have been port mapped and ever so slightly ported to change the port timing a tiny bit. The head has been replaced with a hemispherical dome head specially calculated to the right volume to run on 95 octane gas/oil mix. The new cc rating is now 28.9cc due to larger bore of new top end. The flywheel has been lightened. The timing has been advanced. Massive dominator tuned expansion chamber. Huge walbro carburetor. Velocity stack. K&N filter. 0.7" drive spindle. Third bearing support added. Chrome fan cover and pull start.



Yes...lost the plot...but everyone needs a hobby eh

So what you going to put it in? Skateboard, bucket racer? Looks mean.

You'll have to use your imagination a little at this stage.



But this pile of "parts" will be made into a goped roller...the motor will go on it. Will be badass!

Just googled it, yep that is going to be nuts. Be sure to show us the final result.

How old are you? I've missed something in my life! Am I'm to old to catch up? I'm pretty good at two stroke

Knocking on 40yrs old...still 18 at heart

Knocking on 40 FFS 26 yrs ago I thought that was getting old! Just outa nappies now, where did 26 years go ?
