This person reports "that he floated his valves at about 7,000 rpms." He states he was in 4th gear and running at high rpms when passing a semi. Instead up-shifting into 5th, he accidentally down shifted into 3rd. As a result, several valves are bent. Note ... to Honda a "keeper" is called cotter.

Symtoms:
- tapping noise
- back firing
- poor mpg
- lack of performance and misfiring on acceleration
- dies at idle

Now, THAT sounds expensive! Probably cheaper to find a used, low-mileage motor than to rebuild that one.

time to look for a new engine.

all of the Goldwings are interference engines, and if a valve floats, it is going to hit the piston.

unless he is a good mechanic, that engine is toast.

he can buy another bike almost as cheap as it will cost to replace that engine.

I can watch YouTube all the time on the app on my phone but with links to YouTube like this it says that I don't have the correct browser to be able to watch it. A bunch of crap.

I use Firefox on my cellphone, give that a whirl.
but, for me, a phone is not anywhere good enough to read forums.
you just can't get the big picture. I just won't do it.

I just now sent myself a link via email which sends links to Firefox as the default browser

The YouTube video came up inside this thread, just like it does on my laptop.

I would pull the heads and inspect the piston crowns. If they are not damaged too bad, I would buy two used heads off of EBay and carry on. Less than $500 repair. If the pistons have bad damage, find a good used engine to swap it out with.
