I'm confused. Surely a faulty starter relay/solenoid would stop it from cranking. Fazer69 says it "cranks strongly" but won't fire.
Can a faulty solenoid stop it from firing, even though it's cranking strongly?
Sprocket misalignment will wear out the chain prematurely. Don't dumb down its importance. I wouldn't be happy with that difference either, but I suppose I am a perfectionist ..
