Buddys 17 axys went down on us Saturday just shy of 1800 miles. He bought it used with 1400 and put an SLP pipe set on right away. We rode it together 4 days out west thing ripped, rode 1 day in upper michigan, it ripped, and the next day it started bogging. We've been chasing the bog since and tried everything but i had a bad feeling about the motor even though it compression tested at 115 psi. After our ride Saturday he was going to get a leakdown tester but it lost a cylinder with 1 more ravine to hop out of. Anyways, this is the intake side of the PTO piston. Exhaust side is fine and so is the mag piston. By looking at this piston it explains the bog, but do you guys really think it looks bad enough to lose that cylinder? Sure would've thought itd stay running. Thanks
