Need some info. New to 2strokes
I bought a VERY nice 2001 KDX 200, took it for a ride today and my silencer got so hot it melted the FMF decals that were on it.
All I know about the bike is it has the Airbox lid removed, it has an FMF Powercore II Silencer/FMF Gnarly woods pipe and fresh piston. The KIPS valves are working and reeds look good.
Carb jetting is: 155main, 1174 needle in the 2nd notch down, and a 45 pilot.
Seems to run STRONG on the topend but down low it seems rich. It smokes a LOT at idle and will die if it idles long. When I got home I looked into the silencer and it was completely Dry. No oily residue, just dry soot. Anybody have an idea what would cause the exhaust to get that hot???

Re: Need some info. New to 2strokes
That sounds weird. Have you looked at the spark plug?

Here is my recent plug chop. 5th gear WOT for 10seconds. It's a little darker in person than in the pic.

Re: Need some info. New to 2strokes
I think I have figured out why the stickers melted. I pulled the silencer apart to check everything in the exhaust and the rear half of the packing was completely gone. I would imagine that would generate enough heat in the aluminum housing to burn stickers and then some don't y'all think?

Am I seeing what I think I am or are you having a joke?
The second plug has left 2/3 of its self in the hole. The colour is a few seconds fron aluminium spots on the insulator. Possibly from a air leek at the breake.
What a beauty

Re: Need some info. New to 2strokes
I chopped the threads off with a cutoff wheel so I could get a good look at the insulator. What do you mean by the color being a few seconds away from aluminum spots? Leek at the breake???

Re: Need some info. New to 2strokes
Plug looks fine.
I suspect you are right about the silencer and the missing packing. You may be running more fast stuff than the previous owner, that's why he didn't melt the stickers.

Re: Need some info. New to 2strokes
I'm hoping so. The plug isn't as brown as I would like but it's not totally grey either. Packing should be here before this coming weekend so we'll see if it fixes my problem.

Re: Need some info. New to 2strokes
I've been running belray H1-R 2smoke oil at 32:1 but it's not readily available in my area, I'm considering switching to another brand that my local shop carries.
Here are my choices:
Maxima castor 927
Motul 800
Maxima super M
What do you guys recommend, and what ratio?

Ok sorry. I am going to back out of this conversation. I have never looked at a plug exposed like that before so have no reference points to contribute.

Well normally I would just look down in the end of it, but with the problem I thought I was having I wanted to be dang sure what color it was.

Castor may be problematic with the KIPS unless you really keep after cleaning it. I would go with Motul 800 myself. That or Motul 710 is what I use in all our smokers.
