Tappets on a new bike?

evening all. Ive noticed today my er6 has an occasional tapping sound when you listen closely. Is this normal for a bike engine/ parallel twin? Im new to bikes but from a car background it had

Me thinking that tappets need adjusting.the bike only has 380 odd miles on it though. Thoughts?

er6 tapping

I take it the bike is new?? If so, take it back to the dealer under warranty.

Tappets don't need doing on an ER6 until 15,000 miles (IIRC).
Could be a leaky exhaust gasket or slapping cam chain. It should be neither considering the mileage.

Whilst the engine is idling and you pull the clutch in does the noise become less?

Very few bikes have tappets,yours is a double overhead camshaft and clearances are set with shims of various thickness.Yours being a new bike should be set at the factory and should be checked every 15,000/20,000 miles (in the service book).Tapping will be louder on a cold start but should disappear when oil is circulated.Just ask at the dealers what they think the noise is.

Hi Nick

Think the guys have about covered it,just like to say the bike hasn't reached it first service period yet,so when you take it back for its first service(in the next 500--1000 miles)just mention your concern of the tapping noise and have them document it in there service record incase of a problem in the future.Good Luck
