float bowl sizes

[mazza]

is there a size differnce in the float bowl sizes i.e 550 /750/1000 and would the emolsion tubes in a 550 carb need to be replace with a 750 set or would they be ok [i have rejetted a set of 550 carbs with 750 jets]

The float bows are the same. As far as your jetting, let us know how it works out for you.

To be sure I'd check an online parts supplier like partszilla. Look up both carbs and see if the part number for the emulsion tube is the same number.

so far the y4 is an obsolete part now but they use the x5 tube in the 850g
