Hello!
Just bought a '93 750SX off a local guy for pretty cheap. It ran 148/148psi day one and ran pretty well, had some starting issues. Took it out for the weekend and it crapped out, wouldn't start. Initially thought it was head gasket related because it was overheating, but as it turns out I had completely lost compression.
Today I replaced all the gaskets on the top end, cleaned out the water jackets the best I could ( trying to hunt down overheating ), and replaced the starter. Did a compression check and found 0-10 (gauge doesn't go that low) PSI in cylinder 1 and 148 in cylinder 2. Engine turns over with no resistance.
So what did I lose, and where do I start? Never really wrenched on standup's before. The cylinder is a grayish color.
Thank you for any tips/advice!
