Hi all. I have an 81 cb 750k with 7800 mi that sat in a garage for 30 something years. The engine is out and on a HF engine stand. I can't turn the crank, even after letting penetrating fluid, the oil sit in the cylinders for several months. The carb bank was off and there were no spark plugs in any of the cylinders. There was water in each cylinder which I siphoned before adding the penetrant and oil.
I removed the oil pan, no metal, just black sludge. Oil screen was really clean, just a few non metallic particles. So, I was able to remove the intake cam but I cannot get the chain from the exhaust cam to the crank loose enough to remove that cam. I did get both cam sprocket bolts out. Just can't seem to release enough tension to loosen the cam chain.
Any help would be greatly appreciated!
