i have a 96 cr 250.i have just bought a pro circuit pipe from motosport outlet because i wasnt happy with my fmf gnarly pipe.i saw a shootout article in a 96 motocross action mag,and it bragged about the great mid and top end power on my bike.but with the gnarly all i had was mid and nothing at all on top.it just seemed to take away power in the area that the motor was bilt for. ( i do realize that the fmf is for low and mid). but without wasting any more of your time,what would be some baseline jetting for my bike.or does pc have a website with some jetting specs.
i have a boyesen rad valve , i live at sea level, jetting for a 75 degree day.
now i am running a 175 main,52pilot stock needle.
i was thinking of running a 172 main. i am running amsoil 100 to 1 at 50 to 1 with 92 octain gas.
any help would be great.
