Bob Siegel, my next door neighbor before I moved out west, now works for MFI in Woodbridge. Guy can fix about anything. Shane, the half owner/service manager, would be one to talk to. They're not a Suzuki dealer of course, but Shane told me several times that, depending on the job, they'd work on other bikes. He's an honest guy and worth discussing issues with. Tell them Dan referred you . . . . maybe they'll claim me . . .
George at Beemers Uber Alles in Manassas is fantastic--but sticks mostly to beemers and Urals. Still worth your dropping by to chat. You could again risk using me as a referral . . .
Heard excellent things about Khan, but never went there.
