SX Head for KTM 200?

I'd pull the head, measure the squish and see what its set at. My guess is, its 1.5 - 2mm. You can increase that a tiny bit by decreasing the base gasket and you will gain a bit of top end for sure. You might also wanna make sure everything is OK in there, perhaps you're loosing compression for some reason. I've ridden a 200 and the thing is a lightening bolt, so if your having a problem, it might just be time for a new piston and rings.

There is no current 200SX, so no go, and I am not sure the 200 SX of old was that much different, if any.
For topend, either have your carb oval bored, or buy a 38mm carb, and install a 144/150 CDI.

I have gained top end and overrev with the fatty pipe. Stock expansion chamber falls off the pipe as soon as it gets on the pipe.

The stock pipe signs off way to early aswell, with the FMF it'll scream to the moon.
I've been contemplating getting a 144SX CDI and seeing what that does to the powercurve also.
Video from the weekend with the FMF:

I can tell you, you will like the 144 SX CDI, hotter from bottom to top, especially for the riding you are doing.
Even with FWW, and a Gnarly, mine will still break traction when it comes on the pipe if I am on it hard in 5th/6th.
Wow, mine never gets to see that kind of rev for more than a few seconds. LOL

the KTM hardparts pipe for the later 200's adds a lttle top, as well as a little upper-mid hit. If you like linear power, most of the hit can be dialed out with a powervalve adjustment. You don't lose much, if any, on the bottom with this pipe.

Thanks. The Fatty pipe ended up adding quite a bit of revs while still keeping the bottom pretty strong. My next pipe may be the powerparts or a pro circuit as the fatty is getting harder to get a hold of.
