Hey guys, my brother just bought a pretty nice 05 YFZ 450 all done up and stuff. The thing is it needs jetted really bad. And i woulda been able to do this w/o asking but I never messed with an FCR or a YFZ. I know most of you guys know your FCR's so can yall give me a roundabout starting point. The bike has an ESR alluminum Intake w/ uni filter and full Alba Exhaust. This is what it had in it and it ran like hell and shot flames about 2 feet and popped quite a bit and i know its pretty lean.
Needle: Stock
Main: 170
Slow: 42
Leak: 90
A/F Screw: Stock and havent checked how many turns its out yet.
If yall can school me up on FCR's a little and put me in a good ballpark area of where i should be closer too let me know and i would much appreciate it.
