Try this: A tutorial with picture.
I messed with mine some. Moved it down lower in the rpm range: whoa! too much for the wood.

You cannot move the RPM of engagement on the power valve. It always engages at the same RPM. Adjusting the line as in this article:
http://ktmworld.com/news_articles/GNCC2 ... efault.asp
will allow the PV to open over a longer RPM range, but it still opens at the same RPM. Having it open over a longer RPM range smooths out the "hit".

From your article: "So what I want to do with the PV is adjust it so it opens very late, extending the good low end pull as long as possible, and letting the RPM 's get to a higher point before the PV opens fully and the resulting HP hit does not start the tire spinning nearly so early."

OK, technically I did not move the starting point, but in reality it I did move the "Hit" to a lower RPM. After 1 test I put it back.

Right - having the PV open over a longer RPM spread smooths out the power delivery, which is typically what you would want for woods riding/racing.

In your article you talked about porting and generally increasing power from the 200. Didn't the '07 have the larger carb? Have you seen similar result with the 36mm carb engines? What about the "head mod" or 200SX CDI I've seen mentioned about?

It's almost unlimited what you can do to extract more and more power. That being said, I like the smaller carb because of the added low to mid pull, but you can sure get more upper RPM power with the larger carb. The SX CDI box is a help, but in 2008, the CDI box changed on the XC/XCW, so the older SX CDI box is not a worthwhile investment on the 08 up 200's.

I see that the 08-09 cdi box is a different unit to my 06 cdi. Is there a performance advantage from this box?

Sorry for hi-jacking your thread REX

Yes, it plugs right in, no muss, no fuss!
