Getting the jet needle out of the throttle valve?
mustangfury:
thanks guys! I used an 8mm socket and it went on with a few taps of the plastic screw driver handle. Worked like a charm! Great suggestion. Whoever had the bike before me had the jet needle set for the leanest setting. I put the clip on the needle back at the middle notch and the bike runs like a whole new animal! I live on a 1/4 acre piece of property but in first gear i just gave it about 1/2-3/4 throttle and it wheelied. I think that solved that problem. thanks again!
Only problem left now is that i am getting even more oil spewing out of the exhaust. I attached some pictures to give you an idea. This was oil just from the bike idling for maybe 5 minutes or so. After about 15 minutes of riding the whole back right underside of the tail will be black. Also the swing are will literally have a stream of black running down it from the oil dripping out of the joint between the fatty pipe and the silencer pipe. any ideas on this would be great.
Purpletj:
Silicone is your friend. Apply at every joint including the head pipe. It wouldnt hurt to tear the silencer apart and repack it as well.

Hhhmm.. Stang, if your crank seal is ok, It looks like you may be a tad rich...
Have a look through this link:

If you are sure your seals are good, the next thing I would start with is what kind of riding will you be doing primarily.
Mx, recreational trail riding, dunes etc.
How hard and what level do you think you ride.
What do you have as far as mods on the bike, and do you plan on using race fuel or pump.
What is your elevation and temps.
The more info you have the better chance we have of getting you dialed in.
There is a team green jetting chart that has been really helpful for getting a starting point or baseline.

If you are willing to spend a little time on research and maybe a few pilot & main jets we should be able to get you real close.

I don't know if the crank seal is ok. Supposedly it had just been replaced when I purchased the bike, but you know how that can be. What is the easiest way to check that? Is there a way i can check that without ripping the motor all apart?
I do more of trail type riding, usually sticking to the first three gears. The only other riding i do is out on my uncles farm. 40 acres of open ground so then i go wide open with it. Sometimes i like to just cruise around from point A to point B on the farm though, still pretty quick: transportation. I would say i am in the middle of mx and recreational.
I ride in elevation between 100 and 1000 feet at most and temps between 60 and 90 degrees.
i use pump fuel 93 octane.
For mods, I have an fmf silencer, fmf fatty pipe, standard bore with wiseco piston, and vforce reed valves.
I curently run 32:1 fuel:oil ratio with Bel Ray H1R.
My bike is a 1993 kx 125 J2
Hillclimb#42:
You can go to 50:1, Probably should. H1R is good at lower ratios. Silencer repack is also a good suggestion. I wouldn't change much. My 250 will throw some oil on the fender, when I'm ripping on it. Clean and silicone the rubber boot that joins the silencer to the pipe. I wouldn't change jetting because of oil on my fnder and swingarm.
