Maintenance & Technical > KX500 Original
Jetting!!! Again and again and again!
Paul:
You'll notice a drop in power when it gets to be too much, from there just back it down one. a 180 is what I run at the dunes and my brother in laws CR550 (bored 500) runs a 185M @ the dunes.

Keep increasing the main until it starts to falter

Paul, can you describe term falter? I understand the definition but what will the engine do when it "falters"? Are there any other tell-tales signs of the engine faltering? I'm asking just to be clear. I do understand that a ~1" stream of mix shooting out the silencer would be bad and past "faltering"!!!

Kawdude, I did not really have problems in the high-end, it would just load up in the low. That is why I'm suprised that changing the main up 10 notches has made such a diffrence. I will make more runs after work (6pm) and take the bike out for more tests. I moved up to a 52 pilot and can not get it to idle, even after screwing with the air screw. But, last night I dipped the carb for a few hours and cleaned it off, so it's looking new now and used compressed air to blow the holes clean (main/pilot/ect. ect.), I will fire it up and try to get an idle tonight, it so (hopefully), I'm hoping to find it lean and try to richen it up, maybe a 55-58 or something like that, but right now, I'm feeling rich at a 52.
As far as the main, I'm getting awesome results with the 170. I will purchase some larger jets and hopefully find the median. I do not to alot of WOT runs, like the desert, but am thinking that I could always richen it a bit. I did measure the float height according to clymer, but I'm a bit confused. I am reading about 22mm. Isn't clymer talking about 15-17mm. Which has me confused. If I raise the float, that richens it up. I may also be reading the float wrong, you turn the carb upside downwards? or do you let it rest in the needle without pushing the little springy thing in, am I correct? That is where I measured it. But, if the float needs to be fully resting in the needle, then I did it wrong. But, it looks like I'm seriously lean. But, I was complaining about so much smoke and black plugs.. :?:
Thanks all your help, I'm hoping to get this thing running good! <--I had no motivation until I killed most the vibes with the bars and solid mounts! now, it's the only bike I want to ride. -->

Float level...
Check out this link>>>http://www.dirtrider.net/justkdx/floatlevel.html
It should give you the info you seek :!: With what you're saying I thinking that mine very well could be lean. My concern is the rough sound midway and up...could be pinging :shock: . I can't say that mine is loading up down low...it just wouldn't idle.
Be careful dipping your carb. There is an oring shaped like O-O. That can be damaged by certain chemicals. This oring thing is not available for purchase unless you by a carb. I have read posts that talk about ruining this with dipping but they are probably referring to boiling the carb.
