I HAVE A QUESTION

I'VE BEEN LOOKING AROUND ON THE INTERNET, AND FOUND SEVERAL PLACES TO LOOK FOR JETTING. THEY ALL SEEM TO SAY THE SAME THING...USE A 175 MAIN...THAT'S GOOD FROM SEA LEVEL TO AROUND 3000FT....BUT I CAN'T FIND ANYTHING FOR JETTING ABOVE 3000 FT.
I SEEM TO HAVE GOT RID OF MY BOTTOM END BLUBBERING PROBLEM BY CLEANING THE AIR FILTER THAT WAS PLUGGED SOLID."I DON'T KNOW WHY I DIDN'T CHECK THAT AS SOON AS I GOT THE BIKE HOME...GO FIGURE...LOL"
BUT I WOULD LIKE TO TAKE THE CARB OFF AND MAKE SURE THAT I HAVE THE RIGHT MAIN, PILOT, NEEDLE AND NEEDLE SETTING.
I LIVE IN EASTERN OREGON, AND THE ELV HERE IS 3,200 FT IN TOWN AND 3,500FT AT MY HOUSE...FROM THERE IT'S UPHILL TO AROUND 8,000 TO 9,000FT.
IF ANYONE ON HERE COULD GIVE ME A GOOD IDEA OF WHAT I SHOULD HAVE, I WOULD GREATLY APPRECIATE IT...I HAVE BEEN TOLD 170 TO 172 ON THE MAIN, BUT I JUST WANT AN OPINION FROM PEOPLE THAT HAVE BEEN DOWN THIS ROAD BEFORE.

THX EVERYONE,

BANSHEE (RAY SCOTT---BAKER CITY OREGON) :)

Needle clip in the No. 1 position

Forgot to add, all these jettings assume you've uncorked your bike.. Removed restrictor, drilled exhaust tip, remove airbox parts.
