need some help with real loud ticking more so a like something is slapping together in the top end on the left side of the bike. the bike has about 21000 miles and dont know much else.

 

The top left? Or when you are sitting on the bike, the top right?

Because if its the top right, it may be your cam chain tensioner is loose.

Just a guess though, Im sure someone else will come on.

 

it is loudest on the top left side of the motor sound almost like a nut it in the piston chmber slapping around. im going to pull the valve cover today after work and check timing. i also pulled the plugs last night and they were dirty but otherwise fine, no marks were the piston could have been hitting any of them.

 

also the vin tag on my bike says 900 but the motor is stamped 929 is this normal or did someone do a motor swap?

 

NORMAL.... nobody swapped the engine. The tag will say 900RR and your engine should say 929cm³ this is how it comes from the factory.... why ????

 

Just wondering no biggy. Going to check the cct after work but I don't think that's it cause the noise is definately louder on the top left of the motor. Although I was looking at it and the cct was changed to a manual.

 

Top left is refering to sitting on the bike or stator side

 

ok well found out it wasnt top end the first piston blew out the front of the motor while i was tryiing to listen to it to find the noise. so anyone got a motor?
