On the flushing side of it.....
With a new filter use a mix of 2 parts Butyl Cellosolve to 1 part 10 weight oil, for the first fill, high idle for 30 mins, then drain.
Again new filter, fill again with 10 weight oil, 20 mins high idle then drain.
Fill with what you normally use.
(The best flush solution would be to use a external pump and circulate this mix with engine not running first.)
You have a good chance if you shut it off hot and it hasn't run again cold with the glycol in the crankcase.
*******If it was started again, after it cooled down and run with a load with the glycol gelled up in the bearings, its time to pull the engine.****
(While your at it...)I'd give those stock bolts back to Garmon, and get some 625's there is no comparison in holding power.
I don't feel real good about the chances the bottom end will make it, but here's too hoping for the best.....:Cheer:
