 Engine noises
Hi all,
Could the more experienced guys post some info / description of different engine noises for a 916/748?
How does a piston slap differ from the rockers knock or the main bearings gone noise? What other symptoms appear with the noises and can facilitate the identification of the problem?
I noticed on my 916 a strange knoking sound at around 4000-6000 rpm. It can only be heard while riding and when you accelerate and the rev is around 4000-6000.. I tried to hear the noise while idle, but i couldn't hear it/distinguish it.
thanx |
