Jetting Recommendations?

[CJM]

I have no idea where to begin for a friend of mine who is almost completed a rather good build.

06 TRX450ER
+3 hot rods stroker crank
Stock comp piston
479 big bore kit
42mm bored FCR carb
Uni Filter
Full exhaust.

Right now he has a 132 in there, Im guessing at least 10 sizes up?

wow man idk bout a fcr but on a 450r carb youd have to atleast start on a 180 main imho:confused:

Exactly, FCR is way different ballgame.

start at 180-185ish i would say adjust from there:ermm:

not sure how much your stroker setup will effect jetting, but most stock bore/stroke FCR 450's are around 172 main, 42-48 pilot
