I bought a set of jets for my TTR (new, geniune Mikuni) and they came 4 to a pack. So, now I have 3 extra sets of jets. Pilots # 17.5 and 20; Mains # 107.5, 110, 112.5 $15 per set of 5 jets shipped via 1st class mail in CONUS P.S... not turning a profit, nor trying to make a habit of selling stuff outside the classifieds. Figured it was a niche market.
