Jetting Help, Ktm 2000 65sx

[CaptHookLV]

I live in Las Vegas current temp. 95 degrees elevation 2000 feet above sea level. I bought a 2000 Ktm 65sx used ran good during winter but now is not acting right. ANYone know what needle, main, slow jets I should be using? Or do you know where I can find the jetting specs on this bike without buying the whole manual?

Currently:
main- 210 or 332 N-8
Slow jet- 35
Needle - 5F21 on 4th clip
Slide - 2.0
Spark plug - B 8 E S

as the temp warms (figuring you stay at same general elevation) the bike will run richer because the air density lessens. Try going one or 2 steps leaner on the pilot and main jets. Do any changes in small steps to avoid getting to lean to fast.
