Yamaha makes the TZ, a 250 V-twin that puts out about 90 HP.  $20,000+ (for the 
whole bike) but anything from the nineties that makes 80+ can be had used for 
$2,000-$6,000.  Mine's for sale for $4,000.
Honda makes a similar 250, the RS.  Aprilia makes faster bikes that you can buy 
but in the $50,000 range used.
Honda also makes the CR500 dirt bike, a single.  They only make about 70 HP 
(I'm guessing) but they are tuned for driveability in the dirt.  In roadrace/ 
LSR tune they should make considerably more.  Buying crank assembly, cylinder, 
head, and reed block and making a straight 10 crankcase may be the way to go 
(V16 maybe?).  Note that it gets very difficult to make long press together 
crankshafts so multiple cranks geared together to a drive shaft would be the 
way to go. 
The nice thing is you can tune the way the GP guys do.  Tinker on a 1 cylinder 
engine until it stops blowing up, then just apply it to the multi.
