Took my buddies 93' 900SS/SP out for a spin...did some swerveing as I left the house.. rear end felt a little loose... I summed that upto cold tires...Went another mile down the road re checked with some more swerves.. still felt loose....looked at tires they had plenty of air so I goosed the throttle and it jumped sideways on me. I slowed down and stopped... first place I looked was the axle to see if it was loose... it was fine upon looking further forward the swingarm center pin was sticking out about 3" on the right side.. further investigation showed that the swingarm had cracked on both sides allowing for the pin to come loose. This all happened 7 miles after picking it up from the shop.. just another place to look before you ride it cracked right above the screws that tighten he swingarm to the pin. I made it off the road safely but this could have turned out a lot worse. I don't know if any monsters have developed cracks like these but something to inspect.
