Maybe I am dreaming this but I think I saw an NOS "low compression head" for an MC5 400 on ebay a year or two ago.  It went for something nearly 100 dollars.  I'm backwards on mechanical details but I guess that it would make for easier starting (couldn't you just use different base gasket?).  Maybe there is a better reason for such a head that is more to do with operational ignition/heat production.

"Try that with my YZ490 and you'll end up with a very wet NGK and sneakers would leave you with a very sore arch. His RM did start nicely, with the Lectron carb."

 Better go back and take a better look, the RM has a Mikuni flat slide not a Lectron.
