i have a 81 cb650c and im rebuilding the carbs problem is the old pilot jets are pressed in... new ones in kit are threaded. if i drill em out threaded ones wont fit if i tap the old holes then new threaded jets wont fit.. where might i find a set of press in pilot jets 35s are what i need. got a pipe and 4 individual k and n filters to make it purrrr better but cant find jets. e mail me at dennisno2@sbcglobal.net with advice and info thanks my cb650 custom brothers
