My ol' project.

It's an Aprilia SR50 2 stroke that I updated with a big bore cylinder, oversized piston, 2 stage reed cage, unrestricted intake, racing exhaust, higher rpm drive clutch rollers, and a few other tricks.

Do you have a video of it running?

This was before the new exhaust.

 

[IndyHarry]

After the Leovince exhaust upgrade but before I got a big enough jet to deliver enough fuel.

They call it a replica because it was designed to look like their racing bikes.

My dad got me wrenching in kindergarten, with taking out the drain plug, and lifting me up and putting me in the engine compartment to change plugs. I grew up in my relatives late model garage and at the big tracks. I've spent some time at commercial garages and went to college for computer science. I've been around the block but like the smaller engines. I'm 50yrs old now but fond of clones and predators. I don't know.

I went straight for the modified version . Sounds sweet .
You use it to get to the speed boat ?

Na man. I took a step back and become a sailer. I play around on the river for days at a time for free. I harness the power of the wind.

plenty of aftermarket performance parts and kits for these kind of bikes (mopeds) in Spain and Italy. Many high school kids use them to drive around since they can drive them once they are 14 but they can't drive cars till they are 18 years old. That's why most of the road race bike champs come from these 2 countries.
