	What kind of problem might I be looking at. I did a compression test on my motor and one cylinder had 128psi and the other had only 75. Engine still runs but lost alot of power. any ideas what might be wrong before i rip the engine apart? I know my way around the motor a little bit. Will this be to much for me to tackle? Its a 99 yamaha vmax 500. It's a celebration! Enjoy yourself! Rating: 0 Quick Edit Edit Topic

	It could be as small as a ring or as big as a crank bearing. You wont know until you tear in to it. Anything on the top end is a pretty easy job. Just take your time and take a lot of digital pictures for reference if you arent sure of something. Smoking green since '95 Bleeding green since '06 Rating: 0 Quick Edit Full Edit

	i find it hard to believe it's still running with only 75 psi in one cylinder. like Monsterjay said, you never know until you open up the motor what your getting into. 2006 Skidoo GTX 500ss 1999 Skidoo MXZ 600 1983 Skidoo Blizzard 9700 1982 Skidoo Blizzard 9500 1981 Skidoo Blizzard 9500 1980 Motoski Supersonic (2) 1977 Yamaha SRX 440's 1977 Arctic Kitty Cat 1975 Yamaha GPX 433 1971 Arctic Panther 399 Rating: 0 Quick Edit Full Edit

	Trust me, I took it out and was running bad so I turned around and went home. Put atleast 15 miles on it like that. Even shut it down a few times on the trail to try to figure out what was wrong and always restarted on a pull or 2. It's a celebration! Enjoy yourself! Rating: 0 Quick Edit Full Edit
