BadMotoWeazal Posted October 4, 2005 Where could I buy a jet kit for a Keihin FCR-MX 41 cv. I live in B'ham, AL, elevation is 600' & usually hot & humid. I plan on installing a full Leo Vinci pipe & have removed the backfire screen from the airbox. Any suggestions on jet sizes or needles? Thanks Share this post Link to post Share on other sites

BadMotoWeazal Posted October 4, 2005 Sorry, this is the translation from the Husky owners manual: hi jet 172 lo jet 50 starting jet 85 main air jet 200 low air jet 100 As I said I removed a restrictive back-fire screen from the airbox. I can tell she's running a little lean, no back firing through the pipe on decel. I have notice a little hiccup at about 4700-4900 rpm. Thx Share this post Link to post Share on other sites
