First, let me say that I had a nice long reply written earlier but my browser ate it.
Second, my intent isn't to "get around" the rules (i.e., sandblasted port work looks like no port work) but to stretch them just a little.
But the main goal really
is reliability. I would like to see rather over 100,000 miles of abuse on this motor before I have to pull the heads off. Hopefully 200K or even more!
When I say "stock", I do mean
stock. I can't monkey with the lift/duration of the cam, or even how rapidly it gets to full lift (I think that could compromise reliability anyway), and so on.
Sadly, the flywheel falls into what I cannot do. I can't even really lighten the reciprocating/rotating bits at all, except in the interest of reliability and balancing. (But no, taking 50g off each of the rods for "balancing" is very definitely a no-no.)
So the question remains--what can I do to ensure the maximum of reliability out of a basically stock engine that sees a lot of hard use? ... I do hope Jake chimes in on this one, even though it has been moved outside of his vendor-specific forum...
