i ride an 02 model 200mxc. i want a little more grunt out of it. i ride hills, semi-open and single track trails. NO MX. a lot of the trails have big waterholes. i had no problem lifting the front end over them in 3rd and 4th gear on the yz250 i had.  but the ktm is not so easy. thinking about this combo to help with that. it already has an fmf power core 2 and wanting to add a gnarly pipe, 50 tooth sprocket and boysen dual stage power reeds. then do a pv adjustment. will this combo work good for lifting the front at speed without having to clutch it? i dont want to lose too much top end though.

PV adjustment first, it's free.  You should have no problem lifting the front wheel on a 200 either.  I float along in 4th most of the time and with a little clutch the front comes right up.

50 T sprocket is too low, you will be shifting all the time.

Have the head milled and jet the bike.  That along with the right PV setting and your bike will come alive.  The Gnarly will help low end pull, but do the cheaper stuff first, unless you just want a tougher pipe, or in need of one anyway.

IMHO, reeds are moot unless they need changing.  PV, head, and jetting are the top 3, then the Gnarly.

If you watch a little of my vids you will see me frequently pop the front end up and over logs.

We have 2 of those bikes. Just did the head mod on one of them after a rebuild. Best bang for the buck for sure.No problems picking up the front wheel.

not wanting to mess with the head right now. just want to know if this is a good combo for what i ride. i plan on messing with jetting and playing with the pv. but what about the gnarly pipe and the boysen dual stage power reeds? how much difference will they make?

go back and read my post.  I answered most of your questions.  Having the head milled SHOULD be first on your list.  It allows for easier jetting and just cleans up the combustion process.  Really brings the engine to where it should be.  For $80 or less, it will make those other changes really stand out.  With a sloppy stock combustion chamber, the Gnarly, reeds, etc won't make as much a difference.

so what to do to the head and where to have it done? just take it to a machine shop and have it milled? how much to have cut off?

You have a great person right there in Kentucky.  Trey at Wildcat Motorworks.  You tell him what you are looking for and he will set you up.  He likely just needs to know what your X dimension is, (top of piston relative to the top of bore at TDC).

Here ya go:

Gross is right, the head milling will do more for your overall performance than the exhaust pipe and it's half the price or less.  I would add one thing, before you tear it down do a compression test, if you don't know how it's easy just ask.

The reason I say this is because with the head off it people be so easy to slap on a new piston or even just rings to freshen it up. A fresh top end with the head milled is close in price to the pipe and you would know what you've got in there.

If you want your bike to run the best make sure it's mechanically solid before you start throwing performance mods at a bike that needs some told first.

I run an 01 200 exc that is in very nice condition but Ive replaced nearly every bearing, seal, spokes, etc. ironically I run a stock pipe with an aluminum pipe guard. My exhaust has lasted longer than the crankshaft for instance. And many folks say the stock pipe is just about the best as far as performance.

I never had much luck with a compression test.  I just pull the pipe and take a peak.  I also have an hour meter.

thanks for the info. i will check in to getting the head done.
