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.
