I am not absolutely sure on the date. I am just making a guess based on what I found in the oil screen. When I dug out my spring impact driver, I found the fat phillips bit twisted from the last time I had to remove a Honda crankcase cover. You will never find me riding with period-correct case screws.
Several, actually. I am knee deep in fuel leaks from this old petcock, carb bowls and old fuel lines. I would love to know who thought rivets were the best approach to assembling these fuel valves. I am performing surgery on the rivets while waiting on some new gaskets.
