Best low end-mid pipe for 98 kx250
« on: February 11, 2014, 02:34:26 PM »
Like the title says.   I read a bunch of feedback on thumper talk.   For the 1998 kx250 a lot of guys said the stock pipe.   Any suggestions?  Fmf. Pc. Dep stock? Low end to mid. Mostly ride  woods

from my own experience i can say that the 98 stock-pipe is a real good alrounder, for motocross , trails and woods. dep is also a great alround-pipe. feels stronger in the mid as the stock pipe and i loved it to have on my 97 kx250 . i can not speak for the fmf woods gnarly because they are not available in europe

I used Pro Circuit for years and years on my 250s, and was always extremely happy with the increase they gave...
I haven't seen anyone use DEP around here in years...not even on the 4Ts...
but if you want off idle stump pulling low end, go with the FMF Gnarly...

Great responses.  I will take that into consideration.   And as always this is for my tecate 4 with the "1851" jug 98-99 kx250.   Motor im having built is going to be 310cc 5mm stroker.  Anyone else feel free to chime in.

Totally jealous! I've always wanted a tecate 4. Had a 85 t3 way back in the day. That is the reason most of my bikes are Kawasaki :P Post some pics so I have something to drool over lol

I've always ran PC pipe. Gnarly woods you lose your top end for the added lows.

It's hard to keep a drivers license riding a 2 stroke dirt bike on the street.  If you drive within the law they are VERY boring.

I never liked the gnarly woods for the same reason. Great bottom but it falls on its face in the mid to top.

I dont have a clue how to post pics.  I use a 92 top end now.  I have a couple K5 hinson baskets modified to work.  Right now im having a new front end being built with elka stage 5's and the yfz lonestar billet spindles that use the ltr450 geometry.  Run precision stabilizer and bar mounts.   Rear end being built now to, dominator axle hardkor rear hubs, everything else is lonestar billet with custom dual piston caliper and new style rotor and sprocket guards also custom made.

Shoot me an email and I will send a couple pics for ya to post up

Those are some pretty quads. I am super jealous now. Cases anodized or is that blue chrome or some fancy paint? What pipe is on there now?

Dirk,

What bore/stroke will you be running? Plus 5mm on the Tecate (75mm) or plus 5 on the KX250 (77mm)? I would be hesitant to buy a "Torque" pipe, if you are going to run a 72-74mm bore on the 1851 cylinder you lose a lot of much needed port time area. I have a 1851 with the 74mm & it added a lot of bottom end, but gave up a lot up top & with that setup I liked the FMF fatty over all of the other pipes, as it allowed the bike to have some over rev, and still had the great bottom, versus running flat.
With your stroker setup you will be able to get some of your time area back, and I think you will be impressed with the amount of torque it will have in itself.
Another question, you say you are currently running a "92" cylinder? What stroke is your current setup? The tecate stroke (if memory serves) was 70mm & the "92" cylinder was setup with a 72mm stroke.

Im building a big bore 04 KX250,290cc. In 250 form I ran a Enduro Engineering pipe which worked well across the board. Its a pretty rare pipe, seems like they only made them briefly. Ive also used a Gnarly, good low and mid but signed off a bit early. The stock pipe worked well also. What pipe would you recommend with the 290? I have a never used Pro Circuit Works pipe and have been thinking that it would work well. They seem to be a mid to top oriented pipe. Im not new here Im the Flyin Hawaiian. Ive been having trouble getting on the site so I made a new acct. up.
