FCR carc on a predator

[brock_fuzzy_69]

so i know that it is a very highly suggested change to go to the FCR carb over the stocker

i guess a 450 comes with a 38 mm FCR stock

but i noticed that some of the dirtbikes will have a 41 mm FCR

will the 41 mil carb be to big

i plan on a big bore kit and a set of cams here very shortly

i just wasnt sure if the bigger carb would be overkill
i do believe that the stock mikuni carb is about that big also 42mm?

If u r goin to put in a big bore the bigger carb is what u need. I have a FCR 40 mm I am selling for $220 shipped.

hey give me some details on your FCR
what machine did ti come off of
i guess they came in several combinations with or without a hot start button and tps switch

or if you have pics by chance
