Idling still wronge, help?

Recommended Posts

I can not get my idle right on this ktm 200. Its definitely rid able as it is, but anything i have i want it to be done right. Here is what is does:http://www.youtube.com/watch?v=rCIGamDC4aQ

I can adjust the air screw all the way in and it still wont make a difference with the way it idles. Im starting to think I may need new jets, but do I get the same number jets that I have in it already?(45 and 169)

Read through this http://www.thumpertalk.com/topic/639828-200-jetting-database/page__hl__%20200%20%20jetting__st__60

I assume your bike has the 38mm carb,so compare to EXC/XCWs up till 2006. In 07 there was a carb change,so settings for bikes later than that will be no help. What needle do you have in there,and what position is it in? The 45 pilot is the most common,and most seem to stick with it.

Not sure about my needle position. I just did reading and may check it out this evening. I May need to buy another 45. Mine was dirty (greenish) so i cleaned it. but ya think I could use a new one?

pull the pilot jet and thread a piece of floss or thread thru it and clean it until no dirt shows on the floss. put it back and see if you can get the air screw to affect idle to low speed running. Maybe the air passage is blocked with crud. Did you pull the air screw and flush the passage when you cleaned the carb?

It doesn't seem likely that the pilot jet size would be far off, but you should be able to improve or make poorer the low speed running with the airscrew.

Isn't there a two stroke guru in your neighborhood? Get some trade goods and go looking.

I have the needle out now, Im getting ready to see what its set on. I cleaned the carb and jets good! I set the carb in a bowl of carb cleaner and let the whole thing soak. I took the jets out and did what you said. Il check the crankcase seal in a few. Not that I can find, I dont feel like taking it to a shop, but Il double check.

If the bike runs ok from 1/4 to 3/4 throttle, leave the needle clip where it is for now. The needle does not affect the idle.

I'm about to just load up and take it to a shop. I started it and let it run some, then I sprayed carb cleaner onto the boot and reed valve gasket. My uncle said if there was a leak there it should idle high whenever I sprayed the cleaner. But it didn't. So I assume there isn't a leak there. Next choice would r crankcase. But I need a pressure tester, and i don't really want to waste anymore time on it. I would ride it like it is, but would that mess anything up?

If there is in fact an air leak,it would lead to a lean condition,which as I'm sure you know,is not good. Some informative reads... http://www.klemmvintage.com/airleaks.htm
