from what i read, you need a fuel manager (PCV) to balance out the V&H header with the yoshi R-77's. i'm in the same boat but at almost $8 bills, i have to sit back and wait a bit for that kind of coin.
^ so your saying he can run v&h headers with r-77's and no fuel manager?

You are close to a super talented tuner in Washington State. Check out Nels at 2wheeldynoworks. About a 2 hour ride for you. He can do your ECU and Power Commander V for a sweet tune. I run the V and H header with Leo Vince slip ons. I had the header and Yosh R-77 before. Just changed out for the looks. You will be very happy with the tune and your gas mileage at partial throttle "freeway droning" will be improved. Tell Nels Ziggy sent you... ( Sooke, BC, Vancouver Island )
Could you post dyno sheets ?
