spokerider Posted February 21, 2009 Report Share Posted February 21, 2009 After researching to the limits of "google", it appears that a "Keihin PWK 28 29S" carb is a direct fit for the 348. This flat-sided carb appeals to me as the swap should be *simple* The Keihin's intake and airbox diameters match that of the Amal MKII's measurements of 35mm diameter at the intake and 49mm diameter at the airbox. This means that the manifold and airbox rubbers will fit the carb. Anyone know if the [ oem as factory new ] jetting that the Keihin comes with will work for the 348? If not, which jets would need to be changed out and to what? Thanks. Quote Link to comment Share on other sites More sharing options...
feetupfun Posted February 22, 2009 Report Share Posted February 22, 2009 The diameters may be right but is the length right too? Quote Link to comment Share on other sites More sharing options...
spokerider Posted February 22, 2009 Author Report Share Posted February 22, 2009 (edited) I see the length of the PWK 28 is 83mm. I haven't measured the length of the Amal MK II yet..... http://www.keihin-us.com/am/products/pwk.php And the Amal MK II is 93mm.......... Looks like I need either of the rubbers to be 10mm longer or I modify the airbox hole to be 10 mm closer to the carb and use the oem airbox rubber.
