KX 85 2mm stroke or 100cc cylinder.......

Which one would you? I have a cylinder where the chrome is flaking (Kawasaki imagine that!), thinking of sleeving down to make legal mod. Although we mostly race outlaw series here in Fl. Most just slap on bigger cylinders, but I've heard the 2mm stroke really wakes up the 85.

we're doing a stroker on my sons 100 right now. I sent the head to BC Racing in Mo. Bob is familiar with this and he a great guy to work with, Just remember the head has to be machined and he needs to know what piston you're using or get the measurement from the deck to the center of the piston at TDC. Mine was 2.27mm with the stroker crank. Then he knew exactly how much he need to cut out. Also this was on an 06+ head, the 05 and earlier were different.

I've got 2 heads cut slightly different, that and a little experimenting with base gaskets I should be able to get the squish right.
