Message: [QUOTE="m0rie, post: 755616, member: 36827"] If your compression is at the upper end of the service limit then your top end is most likely just fine. If this bike is still new to you I still tear it down and check everything out. If nothing else take off the head and clean out the kips ports and valves. They get covered in carbon very easily. Wiseco pistons come in one stock size 66mm. They then go in 1mm overbores. This is different than the pro-x pistons which are sized to the OEM bores of A-B-C-D-E. So if you get a wiseco you get the standard one (66mm) -Maruice [/QUOTE]
