Is anyone familiar with how a stock 2000 kx250 ran, and how a pro circuit pipe made it run? My recently rebuilt "basket case" 2000 kx250 has a pro circuit pipe, 304 shorty silencer, two teeth extra on the rear sprocket,and what looks to be carbon fiber reeds. Its a sleeved, unported cylinder also.
Anyway, right on the very bottom end its soft (as in i have to slip the clutch when pulling out in 1st gear); the midrange pulls hard, and the top end just keeps pulling. I literally run out of road and the bike is STILL pulling hard on the top end. Every dyno chart ive seen and test ive read says the bike doesnt rev far.
Does a pro circuit pipe add this much top end? My bike's powerband seems to be the opposite of how it was described in tests. Anybody have experience with this model kx that i can compare notes with?(kips valve is fine by the way!)

Here's one of the 2000's I had
With PC pipe
Swapped out the cyl, ignition and pipe for 98 stuff, the bike is more ridable (for me) low-mid power.
My other 2000 I bought blown
Complete engine rebuild, stock except V-Force reeds and PC pipe
The Shop
A carb spacer is ~$20 and you should be able to score a used OEM silencer (or spark arrestor) for next to nothing.
GREAT job on the build, bro. You and I chatted a while back about your plans, and now it's straight AWESOME to see your bike up and running. Sometimes Vital reminds me of the features in Hot Rod magazine -- yeah, it's super cool to oogle the big bucks builds and replicas, but a completely self-sourced and executed rebuild done well -- like you've done-- is the essence.
Sheesh, anybody with a fat wallet can throw $$ at something, it takes skill and ingenuity to build a bike right on limited resources.
Tip of the hat amigo! Hope some of my suggestions are helpful as you continue your shakedown & set-up.
Good stuff sir.

Haha just kidding!
Jay, do you know what year silencers fit the 2000 KX250? I want a PC shorty or possibly stock for mine.
Ace, Let me know if you want to sell the PC silencer you have.

And thanks for the input Jay. I'll stick to 99-02 if I go that way.

PM me your address and I'll pay EBay and send it your way.
By the way, my spark arrestor is an FMF turbine core drooler. It needs repacking anyway.
