Hi Guys I have a 96 KLX as well as an 09 and my 96 shoots flames on decel, which in the garage is pretty exciting IMHO but obviously not ideal tuning.
I am running no lid on the air box with stock filter. I have a staintune exhaust as well. I have checked the carb and its running a 132 main but not sure on the pilot. everything else is standard. I also have trouble starting it.
Any ideas what I should do.
After reading other posts i suspect a 138 main and a 40 pilot. Is a 35 standard.

 

I wanted to upload a video but it wouldn't let me...

 

Just took out the pilot and its a 38

 

Upload vid to Youtube then link it here.
Maybe check the valve clearances.

 

Way too rich, there is alot of unburned gas in the exhaust. I saw a 06 klx shoot flames before... pretty cool. Main jet maybe too big, needle setting off?

Hey Westy
I did a top end rebuild my self as I bought if of ebay with a holed piston where a valve have broken. So possibly any number of things could be wrong up top like poorly seated valves and valve clearance etc but I did check them and double check them but..... well I'm no mechanic

 

Those are little flames, the one i saw had a 12" flame come out the end of an HMF muffler..... its just too rich....

 

Post up another video at night or at least turn off the garage lights...come on man don't promise a light show and then not deliver...LOL

 

I don't see why you'd want to stop the flame deal. In fact, it looks like you need even richer jetting for a better flame. I agree with deej...that's pretty weak.

But seriously I agree with the responses that indicate a rich jetting condition. Maybe I missed it, but do you still have the fresh air exhaust system hooked up?
