I believe it's been done (superchaged) by someone with a few engineering clues. Story goes that is wasn't all that great.
I've never seen it myself.
I have long thought that a 100cc twin based on half a 250/4 would have some potential but the effort/payoff ratio isn't good enough for me to embark on it as a project.

It is.... but i guess i should have typed XR200/Xl125s
All you ever need to know about Turboing well in (simple form) for working around stock set ups

I picked up 2 complete FZR250 motors for $60
here is the difficult to source bits.
Forged pistons dished for 6.5:1 Comp for a 48mm bore.
And shit did i try.
Found a suitable cast pistons but lifespan would be short.
the other bit is the destroking with metal spraying the crank or custom job$$$$$$$$$
The rest of the parts are easy intercooler easy familar starlet etc
reg and fuel pump here http://www.turbogemini.com/Turbo%20Accessories.htm
The rest of the mods i could do my self so $$$$$
Two strokes are lighter and would be cheaper and more reliable unless you are gifted and or have a huge budget....... would be fun though.

Doesn't matter what carbs you run. If you put them in a pressurised box and feed it air, the balance is always perfect ans there's no danger of pumping fuel out of the over flows.
Not optimal but probably get away with juggling rod length / stroke to get compression down, keep to forged flat tops. Custom crank isn't that hard, but I've got the same problem; I can only afford to do shit like that if I spend most of my time working...
Blown two stroke eh? Suppose there's less to spend time on.
Go soothingly on the grease mud, as there lurks the skid demon
Back to Steve's bike. I dunno about just handing out my 40 horse GT motors willy nilly mate. Might need to let me have a go at some monster wheelies on the MT01 first.
"Non-competition" is the determining test for legality.
I know I should let this die down and let Mossy have his thread back bu I can't help myself...
Flat-tops would decrease comp hugely by themselves, the 250/4's I've seen inside all have contoured tops to get the 12.5:1 or so ratios that they run.
Main problem of all this is that the motor is just so damn tiny.
I elected to get a much more cost efficient 2-stroke. That's a comparably easy build but it still stretches my resources super thin.
