Well figured I WOULD SHARE MY MISTAKE WITH OTHER RIDERS. I have a 98 GSXR 750 with a power commander back in the day it was actually putting out 192HP to rear wheel. Well as of lately it had alot of power loss so in my wisdom i decided to do a compression test! What I found out i was running about 70-75 pounds of compression on cylinders 2-4 and on #1 85 pounds, so i decided to do rings after waiting a long two weeks due to being special order cause of my bike being so old they arrived. The tear down went good along with re-assembly. Pistons looked good and the head no leaks did few test turns to make sure rings seated before head placement and then the start. Wow i got power back she piced up front wheel by power instead of clutch upall was going well then the death knock happened. To make it quick and short i blew apart @2 piston to a million pieces and the connecting rod went threw the front wall and the remainder pieces traveled to #1 and punched the head and snapped the jug walls. Lesson learned as old as my bike is if your gonna do the rings do the pistons and connecting rod shafts with new clips. In short if you have the original pistons upgrade those with the rigs she couldn't handle the new compression on old pistons. SEE PICTURES ATTACHED!!!
