Crf150r knocking sounds

Recommended Posts

My timing chain broke last week and it skipped a couple teeth and my piston came up and hit my intake valves. The valves didn't look bent or anything they just had witness marks on them. I got a new timing chain and threw it together and now it's making a Knocking noise, any idea what it is?

Since the piston hit the intake valves, there's a chance the connection rod was bent.

 

IMO, even if they appear straight and un-damaged, re-using valves that were hit is taking a big chance.
