Just tried it out and had to make some additional changes, as expected. Got it warmed up good, then started adjusting the mix screw, ended up at about 1 3/4 out. Took it for a run again to do the Roll Off test and it surged when I let it off a bit with the 147.5 pilot, so when I got back I swapped it for the 155 and buttuned things back together. Tried to readjust the mix screw, but didn't really change anything there. Ran it for the Roll Off test and it basically maintained when I let off so I guess I'm about right. Still backfires on even mild decelerations, so I may still have to adjust the spacer or the TEV spring, but I'll run it like this for a while to see how it does.

Conclusion:
36" Open Fishtail Pipe w/minor baffling and a Cone filter at my elevation of about 4600' required me to run a 155 main and a 60 pilot.

Maybe I can get out for a Father's day ride tomorrow, or if not, Monday 6/20/11 is National Ride to Work Day
