My 1974 1150 has not been started in 5 years and before I spend a lot of money and effort on it, I want to perform a comp. test to see if its worth it. I dont know if the motor was preped for storage after it's last use, but I doubt it.<br />I think it would be beneficial to lubricate the cylinders before cranking the motor over, but this may affect the accuracy of the comp. test readings.<br />Any thoughts?

Not having the motor warmed up will compromise the test more. Go ahead and lube them, but a bad reading could be a mere matter of stuck rings, which can come unstuck with a de-carb.
