Tappet/ticking sound?

I’m resurrecting thread because of a noisy lifter after waking up the box from a long sleep. I put a bottle of marvel mystery oil into the crankcase and let it idle for twenty minutes and shut it down. Restarted the box today,(two weeks later), and low and behold the noisy lifter is silent and the entire engine seems to be running quieter than last year. Will change the oil and should be ready for April.

Good for you & thanks for searching before starting a new thread !

There is a engine oil made just for our engines, "DT40" made by engineers that know these engine's best.

Oil was supposed to be changed at end of season last year but winter hit hard and early here and garage space was sparse so it didn’t get done.

I’m a motul fan and run it in my bikes. I happen to have a gallon of 5w50 edge and another 0w40 edge so that’s what’s going in next. If I had the money you have wrapped up in that engine I would probably consider the dt40.

Just posted so people know that the mystery oil works if the lifters aren’t too far gone.
This board can be hard enough to search so I didn’t want to add confusion.
