hi everyone. i have won a keihn FCR41mm for my FC 470 - 2001model. does anyone out there know what jets/needle i should change to, or run whats in there (the keihn is off of a yz426 2001. it currently has a 162main jet. 72piloti think the atomiser is 42 and needle and needle jet is standard for the 426. also i've just put a new piston in my 470, how long do you run it in for? many thanks.

run that piston in for 15 hours. the 470 has a horrific history of picking up.

jetting is in the doc under carburation. the doc is on the left of your screen and it says 'owner's doc!' in the title.

good luck.
