Okay, so I've read the entire thread. My question relates to the Raptor 250 crankshaft. You say that it will work, but will require different timing gears and chain, If you can run the Raptor crankshaft, then why can't the Raptor pistons be used?
My interest in the Raptor crankshaft is because I have recently discovered that Hot Rods, Inc.
offers a +4mm stroked crankshaft with shortened rod that is a direct bolt in to the Raptor without the need for a cylinder spacer. On top of that, pistons are plentiful in a variety of sizes and compression ratios. I'm thinking that if I could make the Raptor crankshaft work, and put a bigger sleeve in, and run a 78 mm piston, well wouldn't that be nice?
If this isn't an option, what about using the Raptor inside cases, cylinder and head setup, with the TW longer drive axle? Or just use the Raptor pistons? I believe you wrote that the Raptor pistons cannot be used, is this because of a difference in wrist pin sizes or wrist pin position? Both of these problems can be overcome within the rod.
A lot, I know, but...
