Hello guys, I want to buy a used motorcycle, this one has been in the garage for 5 years. I don’t think the engine is fixed, but now I’m interested in how I could check it at all. The machine has no kick starter and the lid of the ignition device or the clutch lid lets you unscrew definitely not every seller I’ve already read out with spark plug and shine in if you can recognize rust on the piston, but that’s somehow too unsich he. So if anyone had a great idea, I’d be interested in it. Thank you to everyone.
