Today I tested my charging system too look for lost energyon my 1970 Commando S type.
After a night ride with mostly high-beam on the battery was flat.
After charching the battery I had the bike running on it´s mainstand and revved it up to 3000 -4000 rpm after warming up.
A test ride was not possible because of a dropback to winterly conditions here in Germany.
Test was fine so far but I stopped it because the right hand header was glowing red!
It was discoloured before. The left header shows only minor discolouration.
Normal because of the narower curve of the S-exhaust sytem or something wrong with carb adjustment?
Bike runs fine and has a good idle at 1000 rpm. Boyer-Ignition is timed correctly. 2 Amal 930 carbs.
Any thoughts, gentlemen?
