New valve stem seals worked for my GL1100 which would smoke for a few minutes at startup after a few days of non-use, then clear up. It wasn't a heavy smoker and had low miles (I think 26,000) so I was confident the seals were the problem and not piston rings at that low mileage.
The new seals worked and when I sold the Wing a few years later with 47,000 miles, it was still smoke-free.
