Hey guys, a friend is giving me his stock carb and intake tube off his 2004 honda trx450r.I think its a 40mm carb. I want to put it on my 2003 z400. The z is stock except for a fmf slip on muffler and 13/40 gearing and no lid. I know people have put the yami 39mm carb on the z but what does it take to put the honda carb on and is it even worth it. Thanks for the help.
