Default Strange "ticking" sounds from the engine....

Hi everyone!

First of all, sorry for the language...Im from Sweden. =)

I bought a M800 ( Boulevard m50) in february and after a while I noticed a ticking sound coming from the engine. When I rev the bike the ticking follows the rev....I also hear a "whining" sound when driving on low revs in the 4th and 5th gear. This also follows the revs and when I pull the clutch it stoppes. Anyone who had the same problem? Or perhaps its not even a problem? Is it normal?

Actually, I asked the dealer who sold me the bike to take a look at it and listen to the engine and they just said that they couldnt hear anything at all...

The bike is from 2007 and has run 5000 km.

Best regards

I have an 2006 M50 and have the same noises. I have done alot of research about it and talked to few dealers/mechanics, and it seem to be completely normal. I started using AMSOIL full synthetic and it's quieted a little. But apparently, that is just how the motor is. The whining sound I have figured is the air intake starving for air. I suggest a new breather and some aftermarket pipes. Don't forget some sort of efi module. Good luck!
