Hello Fellow Enthusiasts,

This is my first post and I am thrilled to find this site. I have never owned a KDX.
I just purchased a fairly cheap and well used 1992 KDX200 that would not idle and had considerable "spooge" throughout exhaust pipe. The pipe is an aftermarket Pro Circuit fatter pipe and the muffler is an older alum USFS approved arrestor. Packing was oil soaked. Compression was around 180 which excited me enough to buy this bike. 3 compression tests, all similar peak numbers.
After pulling and cleaning stock carb (PWK 35), changing stock needle setting by raising clip up one position to the middle slot and swapping stock Pilot #48 to a #42, plus B8ES plug, the bike started and idle shot up. Shutting choke off made no change to high idle. Turning pilot air screw in or out made no change. Turning idle screw out made little change and motor quit running. Swapping pilot jets up or down combined with moving needle up down incrementally yielded zero starting and idling results. 40:1 synthetic oil/gas mix. Considerable smoke and oil in exhaust lead me to believe possible bad crank seal situation. V-Force reeds in great shape. Performed leak-down test and had soap bubbles appear on right side of head at the exhaust gov cover which I found to be cracked. This cover has a rubber boot attached to it which doesn't seem like it would hold back 6-10 psi. Is air getting past the right side governor rod o-rings? They seem to be blowing a minor amount of oil past and into the cover. Is this right side part of the KIPS system? I have some pictures but not sure how to upload/post. Any advice from this professional group will be appreciated. Sorry about the loss of your friend INDAWOODS. I read some of his posts- what a knowledgeable guy.

There's probably an easier way , but this is how I was shown.

Thanks for the recipe to post pictures. I will give that a try. I'm not too savvy yet with the computer and pictures but trying to learn. Nice looking bike!

Hi there,
I'm no pro, but i've serviced my kips a couple times. Yes, that right hand side cover as well as it's contents is part of your kawi's power-valve system. To my knowledge, and hopefully someone will correct me if I'm wrong - air could leak out there by one of two ways. 1) pressure goes up the main slide valve and out around a faulty main shaft seal into your RHS kips cover. 2) air goes up your RHS sub valve port and up past a faulty o-ring (packing) on your rod, into your RHS cover. I replaced both of those seals when I serviced my kips last, and upon leakdown test, had no bubbles at that cover. How much pressure are you using?

the good thing is that a leak on this end of things is certainly not a big deal like it is on the intake/crankcase. Just look at the crappy seal your pipe has with the cylinder when you don't have a stopper plugging it.

sorry, just realized you said it was a 92. My advice may not have been too spot on then..

Hi guys, just now getting some time to post. Adam, thanks for your reply and Geoff, thanks for posting my picture!

I cant get any pressure on the gauge because all air pumped in during leakdown escapes through that right side power valve junction. I guess I will study about the KIPS for 1992.

Will it help to take the lid off the cylinder , and any tips? Thank you.

photobucket works fine. Since you already have an account there, no need to go to tinypic.... I edited your post to display the image. You can click edit on that post to see how that works with the IMG tags.
