What jetting with FCR carbs with NO AIR BOX just straight K&N filter for race engines?
#1
I run no air box because there is no room with it lowered for flat tracking. I run a FCR 39 and all out race engine. Im curious as to what others are jetting. I use a 175 main in NC 3or400ft above sea level.
Thanks!
Thanks!
