[QUOTE="43Duc748, post: 912824, member: 53859"] My KDX250 is running too rich and I'm getting black gunk leaking at the seals. The bike has an FMF fatty pipe and turbine power-core silencer and a K&N filter. The previous owner said he never changed the jetting and has been running it fine. I think he just overlooked the leaness and ran with it. I've never re-jetted a carb before, but it seems pretty easy. I did a good search of the forums and found different suggestions for jetting: 1) 38/158 , R1367H needle 3rd clip from top, #6 slide 2) 42/165 main, 2nd clip 3) 38/155-158 jetting #6 slide and 1367 needle As you can see, there are various combinations of clip, needle, slide and jetting. I live near sea level and ride in the deserts of Southern California. Can anyone offer some decent asvice or what I have? I'm pretty much an idiot at this, but I am having fun learning! [/QUOTE]
Verification
Which ocean is California closest to?
