Interesting. Looks like the Shark 10 is nothing like the Shark 9.

B10 crank/case + revised 5 port with 1 exhaust. 198 header + 9mm restrictor.

Sounds like a truggy engine, wonder why they didn't do a balanced crank like they did for the shark 9?

I think next up is for me to stuff a shark 9 crank into a B10 and see what happens... Either that or a B10 p/s into a shark 9 guts.
