Ya im glad its something simple also. Ill snap a pic of the new gasket when I get it. The guy from Cometic threw out some thicknesses but I dont remember what he said. I just told him to go with w/e was standard and he said ok. They have real good customer service there.... I was suprised.

Awesome. I've never had to call them. They have good products. Cometic and vesrah are the only 2 companies I get gaskets from.
It's hard to keep a drivers license riding a 2 stroke dirt bike on the street.  If you drive within the law they are VERY boring.

  This should help if you still need electrical stuff.
    I am fit to be tied as to how to get the dab gum stuff organized so people can find what they need...
    Glad you found the problem..

Thanks a lot for that info friar!

Here are some pics of the gasket I pulled off. You can see the correct side of the gasket the powervalve rod goes through and the incorrect side I used :)









Wont be doing that again.

You would be suprised what happens if the powervalves don't open up what it does to your power up top.

That was a big oops lol. At least it didn't hurt anything else. What cell phone are you using? Excellent pics.

I had a 89 kx125 back around 2000. I know there was a big difference if the powervalve was working or missing. For some reason the powervalves in the 125 would only last a couple months. I pulled it apart the first time after I bought it and they were just GONE! very little remnants left. The second time they were about 75% there. I never figured it out. It never overheated but the valves melted away or something. Sold the bike because of it. I would imagine if the valves don't work in the K5 that it would be like riding a 250 or even a 125. Never had that issue yet.
