1993 kx 500 kips valve tuning

[sandblaster]

That jetting chart is very conservative.
I run 52-55 depending on temps at 0-1000 ft.
At 4000 ft I run 52 and my needle at the second position.
I have ran this in my supermoto and my sand bike with no issues...
I think you need to lean your pilot a bit more but it is always safe to go a little at a time...

And yes... I'm open on Monday

MAYBE NOT SO MUCH MUCH ON WHAT IVE DONE TO MY STOCK THUMPER. MOSTLY ON HOW ITS BEEN TREATED SINCE I BOUGHT IT JUST UNDER A YEAR AGO.

MAYBE NOT SO MUCH MUCH ON WHAT IVE DONE TO MY STOCK kx5oo but MOSTLY ON HOW ITS BEEN TREATED SINCE I BOUGHT IT JUST UNDER A YEAR AGO. so now i have a pilot jet 2points leaner and a wealth of information from this forum on how to properly jet the carb so that  its tuned for any situation. that info right there in itself is\ more info than i would have found at any 1 place. and for free even. thanks guys. i also did the thought that crossed my mind by reading the one small reply to my post that i only saw one time. that reply was. "what about the positioning of the lever between the exhaust advancer portion of the kips system and the rod and valves in the barrel's exhaust side that that piulls and pushes.?" i did one thing with a little more attention this time as far as that kips is concerned. i made certain that the position of the rod was on full closed was extending to where the valves inside showed full closed....then when i connected the lever to the connector on the end of the toothed rod id held it so that the valves didnt inadvertently change position when i connected them up to the lever. i never even payed attention to that part the last few times i put ity together., so now with the leaner pilot jet and that ,if my green machine works as it was intended to i still wont know which it was. thats the thing about all the info in a big blast. well i bet it will kick on the first kick tomorrow after work... i need to go to bed . it took 2 1/2 hrs to do the reassemble part from the looks of it. as long as i didnt miss tightening something. thanks you all.

oh ya i kinda spaced of a question that i wonder if anybody knows the answer to .   that crankcase ,the one that came on the 93 i have has the most peculiar modification to it ive ever seen. it has a carbon fiber kawasaki  flywheel cover that has an eagle in the center  with a g around the eagle. plus the bolt patern is the exact same as a normal stock flywheel cover other than the two near the shift lever. they required somebody to put a piece of the material these cases are made of with matching bolt holes for the flywheel cover to attach to on the case. therefor making the space larger in the flywheel enclosure for no other reason than to bolt on the cover. whats the point. this is definitely aftermarket without any real reason . weirdest modification ive ever seen.carbon fiber is good. but why not buy one that fits the case. not make the case fit the cover... good night to ya all.

you're welcome
just keep in mind, those jetting charts are just base lines...the best jetting chart is, wide open throttle chops, and reading your spark plug's color, and actually riding it. The plug is an open book, and will tell you exactly what the motor wants.
I haven't used a jetting chart in several years, as I find I never end up anywhere near close to what they suggest, and they're not good for fine tuning.

"one stroke for producing power and three for wearing the engine out."  i love that. thats awesome.

pretty cool/.... went down to the bike shop and they just gave me the 55 pilot for notta. luckily i brought along the one i took out last night.there are two different styles of thread placements on the pilot jets. now time to go see.

[b4himdude]

 alright guys i put the 55 pilot in the carb and guess how right you are. im sure you already expected that. no anyway i tried the 58 pilot and it WAS still seemingly needing to quit hacking up phlegm. so now the 55 still seems as though she might be getting over the congestion pretty well but not quite. theres still a bit of a itchy throat (so to speak) so my question is if i have the 1 1/2 turns out on the air screw and it idles super once warmed up should i even tinker with the adjustments or go one leaner on the pilot.or should i just deal  with the slight congestion and watch the condition of the plug for a few rides? and if leaner by one is the decision then what is one leaner from a 55? id  first guess a 54 but i dont know the numbering system and how they number em.a 53?  anyway you guys are great. i have some good stories to add to the forums when i have a chance to find em. started at 8 yrs old on a 1980 rm60. talk later

the next Pilot down is a 52...I had a feeling you would probably end up at a 52, so yes, pull the 55, and try a 52.

[b4himdude]

thanks a lot i will do that. appreciate all of your help.

[b4himdude]

alright i went with the 52 pilot and i dont think its better.  is there a possibility that maybe the main jet might be too rich? ive cleaned the heck out of the carb. changed the throttle cable. i have noticed that it seems like when i go passed half throttle is when it chokes up. it does finally cough it out but its not right on the pipe like it should be. it kinda gurgles itself to full power. as long as i stay on it  i can keep it from doing it . but like if i keep the throttle mellow for a few seconds it takes that time to clear out again. whats a size down from a 168 main? oh ya i also measured my float height. i dont have one of those bowl adapters but it looked like it was right as far as the measurement goes the book specifies. . i have about a half float bowl full when i remove it. no spills. so im thinking its probably not that. but i dont know. i hate to keep bothering you all but ,you've got me this far so i hope to stick to where the knowledge is and get this thing dialed in..... thank you.

[Foxx4Beaver]

next size down on the main is a 165, then 162...I wouldn't go any lower than 162.
what position is the needle clip currently in?

[b4himdude]

right now its in the center position. but prior to my ride about a half hour ago i moved it from the second to there thinking  maybe it would tell me something. it seemed to be worse than it was in the second position. so richer isnt the answer anywhere its looking like. the plug is being left a little damp as well. but i have to ride slow from about a block and a half from my house to the dirt.

[b4himdude]

is a br8es hotter or cooler than an eg? plus i have a br8egv whas that?

[Foxx4Beaver]

there's a good chance you're probably gonna need to find a leaner needle, which I mentioned earlier for fine tuning...like an N82P or an N82T
