Its real easy to get 22 RWHP out of GP100. http://www.trademe.co.nz/Trade-Me-Mo...-275479320.htm
Handling is pretty modest though.

My engine knowledge is limited to 4 strokes.. Hence wanting to get a loncin. I have a vision of a short stroke crank..

A supercharged Honda 50.......as the rules allow <100cc supercharged 4-strokes in F4....... you could try this with a Loncin...

So, given that the practical limits on HP with a blower is the strength of the crank and cases... what's the nuggetiest 100cc block to use?

That could always be an option for the future. Building a scmick 100 that could handle 10 or more pound o boost would be a laugh.
Would be easy for me to replicate a stock crank/block out of better materials.
I have in mind a 3 piece crank all made from 4340 for the as yet non existent loncin.

'Zackly.
Can model up new cases and get 'em CNC munched too, need a gearbox, donated from what?
I'd digitise the original and add thickness and webs... possibly cavity for dry-sump...
Any restrictions if we assume the owner makes all the bits?

OK, I know the XL a bit.
Might need some serious FINZ on the head.

Cooling shouldn't be to hard. Fit a copper head gasket fin like on my GP, then spray water on it from a window washer and use a big oil cooler for the motor/gearbox, and spray a little water on that too.
Supercharging is great because you don't need hot cams or to rev the engine hard out, and you can short shift and use the extra low down grunt to drive out of the corners.
In the picture you can see how the oversized head gasket forms an extra large cooling fin.

Here is a look at a motor Speedpro is playing with.......aharrrrrrrrr........4-strokes......great, aren't they.....don't you just love em....

From the rule book:
"Buckets have two engine capacity classes:
F4
2 stroke 55-100cc
2 stroke 55-125cc air cooled
4 stroke 55-150cc
F5
2 stroke 0-50cc
4 stroke 0-100cc air cooled
Engines must be derived from non-competition motorcycles. . . . ."
I think that last line would smeg you unless you could somehow prove that you were making a production run of non competition motorcycles at the time
FFS guys - just buy a bike & get out & race.
Don't you look at my accountant.
He's the only one I've got.

The aussies have dropped the no handbuilt engines rule, its a bit vauge anyway is a handbuilt engine a competition engine even if it has no competition parts because it just is ? Any way you can go to a honda shop and buy a bling CBR150 for 6 or 7 k and it will be potentially faster than a 3/4 developed mongrel. CNC cases my arse !!From the rule book:
