I am still jetting my bike and thought... Man I wish there was a list of ball park starting points for a given range jet size for a given range of elevation.
Let me start by saying that my personal goal would be in the order stated to, ensure reliability, economy and release the least bad emissions on the environment that I can.
A quick google search can give you the elevation answer...
We are relatively low in elevation (2548' at the airport). Around Tucson, desert scrub is replaced by desert grassland at about 3500' and oak woodland replaces desert grassland at about 4000' elevation.
It is true that any modifications will affect your final settings. My intent here is to establish a starting range not a final jet setting as that will vary quite a bit based on humidity, temperature, exact or range of elevation for your given area. I settled on something not too lean for break in but not so rich that it would contaminate the oil and have performance issues.
While I am not done fine tuning my jetting I believe that I can safely say that...
#82 with the needle "C" clip in the center at my 2500' to 2780' elevation in a dry climate is a good starting point. This setting does lend itself to stalling with a cold engine, but that is something I would expect with the current choke design.
So @-2780' = #82 centered C clip seems to be a good starting point for my area and range of elevation.
Does anyone have a list they can post? Can we create a list here if there is not a list available?
