I am about to strip down the engine on my 1977 TS125, according to various sources using an M10 bolt will remove the dynamo, other sources say it has a fine tread.
Can anyone tell me if it is a standard M10 1.50 pitch thread or a 1.25 pitch thread.
Standard 1.5mm pitch 10mm bolt will do the trick. Needs to be quite long – about 70mm at a guess A fine thread is used on the 7mm bolt which secures the points cam and stator to the crankshaft.
