Alright a friend of mine just purchased a 450r and the person who owned it b-4 had it all tricked out. But he sold it as a pretty well stock bike. My buddie is running a stock exhaust,filter,cam,carb, so i was wondering what his carb setting should be, and will 13.5/1 make a diffrence on the jets.



Whats the stock main jet size? and what size main jet would u think we should run with the 13.5/1 piston?
Whats the air/fuel screwm mixture should be. How many turns?



ANy help would be great.
