kx500 with 39 pwk jetting with shaved head/cylinder

[ironmike]

Hi guys. New to your site. Not sure if im posting this in the right place? I just picked up a 86 kx500. Have a few problems but got it running. Ended up getting a keihin 39 pwk carb from an o5 ktm 125 off ebay. Ive looked on this site to get a starting point for jets? Seen that most of yous are using 55 pilot,168 main? Put those in and seems to be running alittle lean (clip is in 3rd slot down from the top. Put 58 p and 170 main (moved clip back to 2nd slot). Seems to be dumping to much fuel? Its a little boggy. Pulled the plug and its grayish and very wet. Air screw is set 2 turns out. Guy I got the bikr from said he had the head and cylinder shaved .065 and 70 over piston is in there? Mods are pro circuit pipe,answer silencer,duel stage reeds,uni air filter/holes in air box. Let me know your in put and what you think about the set up and the whole shaving thing? Ive always rode 3 and 4 wheelers and havent had to many dirtbikes. Thanks in advance.mike

As Tuck stated LOTS of info here if you search. What needle are you using (the KTM?) & what slide (again KTM?)

hi guys. Thanx for getting back to me. I messed with the jetting today. I put the 55 p and 168 m back in and it runs much better. Still not right on. Yes I am running the needle and slide that came in the carb? If carb came off ktm does it mean slide and needle are ktm also? Or are they keihin? Thanx
