just put motor back together. New rods and bearings, new timing chains and guides. Now after it warms up, motor barely turns over and have to let it cool down awhile before starting. I dont think its the crank or rod bearings because I have no lower knock or any metal shavings in the oil. I do have a tikk you can hear in the front cylinder once it is warm and can really hear it with the screwdriver trick. Could the timing be off the chains too tight or the valve clearance wrong? I have 5 hours on it since its been put back together and youd hink if the crank or rod bearings were bad id know by now.
