The KTM 200 Club

[Shhhh]

Soooo... I need your help please! The "200" I just bought.. well it might not be a 200??? So as I'm tearing it apart to do a rebuild, I wrote down the VIN and the engine #. The VIN is VBKMXK.... and according to the KTM VIN decoder, MXK is a 300 SX/MXC/DXC.  what tha???

The engine code (best I could tell) is 4-503-25917. Does that mean anything to anyone?

 

Do I have a 300 SX?

Check the side of the cylinder for the displacement. That is a stock 200sx pipe on it though. Maybe a 200sx in a different frame, but all the pics you've posted it "looks" like a 200sx.

Look on the side of the jug it should have the displacement written on It

look at the power valve adjuster, it's a 125/200 bottom end.

I agree it has a 200 looking pipe. I agree the power valve adjuster is 125/200. The writing on the side of the cylinder housing is:

On top of the cylinder is:

And I checked the spark plug and it's an NGK BR 7, which is what would go in a 250exc and 300mxc.

Something is weird.

Frankenbike?

Frankenbike?

Let's just call it the ultimate BIG BORE 200 kit?

[Shhhh]

Nope, wrong plug. That is the part # for a 200 cylinder.

Just found this post...

Someone with the same question and the same numbers on the cylinder case.

[jkabee]

I wonder if that plug would cause it to run weird.. Poldies, did you see the silencer photo i shared? I'm going to repack it. Think I should get the correct spark plug while I'm at it? 

[Shhhh]

I would, looks plenty saturated to me.

My bike pulls hard from bottom to top with no lag. I can check my jetting and needle tomorrow night after work to compare yours to if you want. I know I wrote it down, can't seem to remember where though!?

I would appreciate that.

I ran a 7 in my bike that should have an 8 it ran great down the street then quit. I then put the 8 in it and it started first kick

Quick question - can I clean out the powervalve on my 2000 200 without taking the cylinder off? Can I just remove the exhaust pipe and get that cap off so I can flush it out with some spray cleaner? I think it is dirty, my power goes a bit flat on the last couple thousand RPMs. I have a ride tomorrow and would like to clean it up a bit, but I don't have enough time or the gaskets to pull the cylinder and do it that way. Thanks for any help!

If I remember, I think on my 2001 200 the frame didn't allow me to get that cap off without taking the whole jug off the bike

[CousinLarry]

That's what I was afraid of. It looked tight but wasn't sure. Thanks! I'll ride it tomorrow and give it a proper clean up soon.

Don't be "afraid" it's really easy to take it off and clean it. Dive in!

[CousinLarry]

I'd like to have the gaskets on hand first! I will order some parts and get to it!

You can take off the frame mounts and pivot the motor on the swingarm

That's how I did it if I remember right

Why not take your time and do a complete top end? Its probably double the work but worth it.

When I did mine I had just finished the top end
