Folks,

Short form: assuming I have XB1200 2004-spec heads, which pistons/cylinders will work with them? XB9? XB12? What years?

I have a 1997 Buell S3 that I am desperately trying to get running, in more or less any form. Rear cylinder is fried; I did an Axtell 1250 conversion and the rear wrist pin came completely apart :(.

Back in 2005 I put XB1200 heads on, 2004 spec, with the right adapter to put those in a tube-frame Buell like mine. Bottom end is stock.

To say that I am desperate would be an understatement. As long as there are no valve clearance issues, screw it, I'll put a friggin' BLAST piston and cylinder back there for now, if they'll fit.

Help! What the hell will fit? I can find XB9 piston/cylinder kits all over the place, probably from upgrade projects...will those work?

I'm in Tucson AZ and need to get this thing rolling by Wednesday the 16th at the absolute latest.
 
All xb models have the same cylinders and heads, the piston make the difference. If you put xb9 pistons into a 12 motor you will have a very high compression motor. Xb12 pistons are flat and xb9 pistons are dome shaped on top
