Ron, you're running Webers with RS pistons now, right?

How'd it work with RS pistons and CIS? Was that the setup you had when you took me out for a spin on LI?


yep.. you rode with CIS & RS pistons. No smog check prob.. although if mix setting is on low side of specs it may bog a little off the line. I'm not sure if it was caused by RS pistons? The RS pistons is a really brainless replacement for the stock pistons. Stock pistons wear much more than the RS and probably are in good shape for only 100k miles. I don't have that experience, it's what I read somewhere.

PS: cross country millage with RS & CIS maxed about 25-26mpg.
