I'm sorry this is kind of a stupid question, but I'm riding my 03 kx250 in the woods and don't need the kind of power that the pro circuit pipe makes. I have heard that the stock pipe (which the guy saved and gave to me) has more manageable power.
Could anyone tell me if this is true? Also would I need to make any jetting adjustments? I haven't jetted in nearly a decade so I'm not really sure where to start.
I'm also getting the 04 powervalve governor spring and a g2 adjustable throttle cam. I can't afford a gnarly pipe.

I actually had the same thoughts on the 2000 I just completely rebuilt from top to bottom.

I strapped on a PC setup and wish I had gone the other way and went for a low-end pipe.I found I had to ride it hard and clutch the s**t out of it in the woods to get it to snap for me....sooooo,instead of spending another fortune on an exhaust....I ended up playing with the gearing a bit since I had several sprockets laying around.I'm at 12-48 rite now and it seems to be working for me.
Since you have the stocker...throw it on and see how you like it...and report back. :-D

as for my jetting...I'm as follows
Main 158
Pilot 45
Needle N3YE (4 steps leaner over stock)
2nd from top
Power Jet 48
Slide #7
I went much leaner over stock...I don't think my jetting will help you too much,because the 03 and 2000 have different setups I believe.

I know on my 03 with a PC pipe setup I geared mine way goofy 14 and 48 to get it to be able to control it in the woods.
