Cleaning valves, what works?

[robert_r_lefebvre]

I've started to disassemble the top end on my GS1150 and noticed a fair amount of deposit on the valves once I removed the valves from the head.

The deposits are a hard black grit which has formed all the way around the valve stem.

What's the best way to remove the deposits?

Thanks in advance.

I put a couple of shots of Berryman's in my tank and some Lucas as well over about a year and when I went to adjust my valves, everything was squeaky clean.

The only way I've ever seen anybody clean deposits off of valves is on a wire wheel mounted on a grinder. Works great.

oven cleaner works fairly well. Walmart stuff sells for around a buck a can. Spray, let sit in shade for 30 min. repeat more 2-3 times. Then hot water from a pressure washer at the carwash. .....Jack

Brass wire wheel mounted on a bench grinder is what Engine Re-conditioners use.
