This one could be a good base to start from,

So the idea is to turbocharger a Medium single banger?
Aren't the exhaust pulses too far apart to properly spool the turbo?

This was done through RS performance in England
Supercharged putting over 85hp at the wheel
Sounds like a real cool project.
Just thinking out loud here,
How would you setup the carb on a blow through system?
you'd need to seal and pressurise the float bowl to get the venturi effect through the carb.
In which case you'd run out of fuel quick as the float bowl is gravity feed, so you'd need to add a small pump in.
most carb pumps only do a few psi.
You'd need a real small turbo like a gt12,
Am I alone in thinking that turbo lag power delivery would be contrary to what makes a motard fun, being sharp and nimble.
What about a suck through supercharger setup?
with the supercharger wedged between the carb and the head.
Jetting would be simplified, and throttle response would be retained.
something like a AMR300 would do the trick (on some small subaru's and off the shelf)
Or may turn a smog pump into a poor mans supercharger.
Does a WR450 run a dry stator and flywheel?
You feed plenum pressure to above the diaphragm, and into the float bowl, and then you need a fuel pressure regulator to keep the bowl fed with plenum pressure plus a few psi. Than you need a higher pressure fuel pump to feed the pressure regulator.
Draw through turbo designs are usually the laggiest. Theres no real reason to draw through, unless you like the way they behave - cranky and bitchy.
Now that's an interesting idea.
Even if it's wet, its not bathed in oil while its running. Maybe an oil slinger and seal will allow you to a shaft out of it.

a system with an FPR and return lines and all that goes with it would be pretty involved. What psi would overcome the floats ability to hold the needle valve shut?
There could be many reasons for lag on draw through turbo systems dependant on the setup, long lengths of intake pipework delaying response, fuel condensing on an intercooler if one was used. But there is no lag on a blower setup so no problem.
Draw through on a blower setup is the most common. A carb is designed to work at n/a pressures.
It would be easier if it was dry, extending the shaft might require an extra bearing for support and that could be hard with only a thin walled case cover. It would add extra width to the engine right by your left leg as well.
Have you found a bike to work from Spanner?
