What's your twin's approximate oil consumption (miles per pint?)
Robert: I can't remember what kind of breather the Mammoth has....[/QUOTE said:It is basically a stock timed breather, except the exit pipe goes over the banjo instead of inside it, so is more like 7/16 instead of 5/16 tubing. The secret is stopping the source - Round Bores, Honda Chrome rings (as expensive as the pistons), no blowby, no crankcase pressure to speak of, mostly standard breather works fine, leaves a little puddle of "milk" if left idling after a good run. I think I'm up to about 40-50K miles on that set of pistons and crank, and by the way that's @ 9.4:1 compression.
Your rollers on the crank pin, will now be 1 1/2 thou small. So do a check now. Save you a lot if the pin and eye is good, no reason for it not to be, re-roller, and do another 40,000.It is basically a stock timed breather, except the exit pipe goes over the banjo instead of inside it, so is more like 7/16 instead of 5/16 tubing.

I have no idea how many miles per pint-provided there's some left when I check it before the next outing!
