[810darren]

i have read alot of forums but not sure how you calculate for the sea level your at.this is what im doing and what i have.fmf fattys,k&n no lid,bore 20 over,mild port job,milling head 20 thousanths,ricky satator timing advance plate.i bought this it is a 1998 first 4 wheeler i always had dirt bikes and still do.went threw and dissasembled carbs did a goog cleaning.i installed 280 mains and 30 pilot jets.but from what i have been reading i might be a little lean kinda concerned.looks like most with this set up go with 320 mains and a 25.7 pilot.i know this subject has been beat up but i dont know how my elevation plays in im at 800ft.should i try out what my set up is now see how she runs when i get it back together or should i change something before i even put it back together.any info is appreciated.

i would definitely start out on what seems to be the rich side and bring it down if needed, rather than be running lean. can't help you much with the actual calculation though. start high, and do a plug chop and adjust as needed.
