hi all. My 94 kdx was spitting oil and missing at wide open throttle so I ordered new jets. They sent me a bunch of jets so I don't know which to choose. I'm 1000 ft above sea level and my bike has an fmf gold series pipe. My choices are 155,158 and 160 for one. The other jets options are 42 and 35. I just would like to know an educated guess. Thanks so much.

Are you around the same altitude as me ? I just don't want to blow the engine being to lean.

Im close to sea level. The higher you go the leaner you have to be. Just start rich and work your way down. I run 32 158 I'm a little rich on top. I have one size leaner slide and two sizes leaner on the needle.
