I'm really excited to see the difference this setup will give me. I hope the snow melts by the time I get it installed! Do I need to jet different?

I guess I should mention it's a 250 cdi. I'm a little slow in the head...

I pulled the stator cover and found a mess of spooge arourd the flywheel

lovely. nothin beats a good ol rusted out flywheel

I also pulled the reed cage to take a look at the piston, and sure as sh!t it's cracked

i dont see a crack but i see some scuffing and gouges. usually the crack starts at the high point of the arch.

owch nipped up on the intake side what ratio oil do you run

Sorry crap pic. There are two cracks at about 10 and 2 o'clock on the cutout, coming up at about 45* angle

I run 40:1 amsoil dominator. I bought this bike from my brother last year for cheap. I'm not sure what he was running.

they could be cracks, double check to be sure. you will get some marks/discoloring there becuase thats BDC. this is what ive typically seen, the crack is at the high point, you can see some 10' o clock and 2 o clock marks that appear to be cracks but they are actually just marks because thats where the piston hits bottom. yours may be cracks but honestly ive never seen them start in that location.

Good call 100hp. Still gonna replace it as y'all ca see it's not to fresh I probably jumped the gun calling it cracked. On the bright side this is a perfect excuse to tear it down and get it ported

Who needs an excuse?, Want to --- just do it!

So much for the 250 ign. This bike is a basket case! The swingarm bolt is stuck, so I'll need to cut it out and redo the bearings. The wiesco piston IS cracked.

Look for this bike in the steelie rebuild section very soon.
