So what's everybody running? I live at 5,000', but the good roads by my house go up to 7,000'.
My current jetting is 135/38. Bike is currently equipped with Cali emissions gear but will soon be stripped to 49-state form.
Stock airbox with K&N and stock exhaust. ...
Bought my '94 as a Cali model from a dealer in N. Phoenix. Been living in CO at 7400' for the last 13 years. Same basic setup as yours? Haven't touched the jets, run a K&N, stock emissions stuff, pilot screws dinked with many moons ago, ... I average around 38MPG, got 50+ MPG a few years ago, but I was escorting a Moped around the mountains at the time.
I wonder... has the fuel height in the bowls been checked? Got good spark? No air leaks?
Oh, are carbs are constant velocity, changes in altitude doesn't effect them that much. It's not *absolutely* necessary to change jets @ altitude, but a few do. I'm not one of them.

I'm sick and tired of pulling the carbs. This is the last time I pull them. If it's not right this time, I'll probably sell the bike and quit riding until I can afford something with FI. I've already replaced both of the air cut valves (outer one was ripped) and the fuel-rail o-rings, they were rotten too.

dial a jet is junk. sorry, just the facts - Steve

135 and 38 isn't even stock cA jetting, stock CA jetting is 130 and 35.
I have my jets kits set up for altitude also, theres several of them running in your area, and I've gotten feedback of high 40's to 50 mpg from them. While your jetting is definitely an issue fuel level will also be an issue, especially if the bike has any age to it. Steve
I and others appreciate the Post on the Jetting. Especially the Down to Sea Level info.
Main Jets are only $1.60 from one of my suppliers.
Good Point, and those $1.60 jets actually come with legible numbers on them.
I have no problem at all buying a jet kit from someone like Steve who has done all the work including dyno time. I could blindly start buying jets and changing them but I have no access to a dyno where I live. The small price I paid was well worth it for the results and performance gains. Mark
