I've been trying to figure out which jets to get for my 02 XRL. I'm at 800-1400 ft above sea level usually. Would 55 pilot and 158 main work good?
I'm also planning on riding in Colorado and Moab this year, What jets should I get for the higher elevation. I'll be running a Foam filter, de-smogged, and most likely stock exhaust.

Right now I have the standard mods (the recipe)with 158 main 55 pilot - Pilot jet part no. is N424-26-55.
Main jet is 99101-393-158. You can get them from Sudco or Carbparts.
I live at 6800ft in Colorado and have driven my XR650L at 25-60 degrees
but things may change when it gets warmer so far so good but I don't needs much choke at start up ,I want to drill my seat at bit to let more air in when it gets warmer
but I am ready to go lower on the jets when it gets hot .I have the stock pipe too

I got a few jets from a Honda dealer today, hopefully these are the correct ones. I got the 55 pilot and a 157.5 and 160 main ( these were the only ones they had ). I ordered the UNI filter and sprockets yesterday and will probably get the Smog block pretty soon.
Here is a link to a pic of them. Do these look right?

Sweet! thats good to know. I'd hate to tear the carb off and have the wrong stuff. I looked on the 4-strokes.com website and they looked like the right design.
Thanks

Thanks, I hadn't seen that one on that site yet. Pretty interesting stuff. I'll have to do a bit more studying to get all this figured out.

i just checked the jetting on mine,i picked the bike up last fall and i was interested if any jetting was done, it has a kn filter no snorkel white bros full exhaust and its a 94 so it didn't have the smog @#!# any way it had a tapered needle with adjustment grooves,160 main jet,50 pilot. i went to a 55 pilot and then drilled the two holes out in the slide to 5/32 and i tell you before these mods the bike would need a shot of starting fluid if you left it sit for more then 3 days, the bike was sitting for about a month before i did the mods and after the mods it fired right up cant wait to ride
do the mods tis well worth it :)
