So I really thought I had dodged the bullet and that it was just a coolant tank issue. But, the coolant spray when going wide open happened again. So I bought one of those testers that tests for exhaust in the coolant. At first there was nothing. But once I got the scooter as hot as I could while sitting on its stand, I did see some belches. And, while it didn't turn yellow, the test fluid turned solidly green. Given that the spray only happens on wide open, I think that makes sense.
So, back to changing the head gasket. I had this week off of work for a staycation anyway so I've got the time. This week has turned into a medical and mechanics repair vacay instead of R&R. But, better that it happen now...
Stay tuned for more of my stupid human tricks, lol.
