So I did my valve clearances at the weekend. (GSXR750 K5). Loads were out of spec so lots of new shims.
Everything seemed to go OK, but when I took the bike out it is making a horrible tapping noise, louder than you'd expect from a cam chain tensioner not working properly, and it is directly related to engine speed. Runs OK though.
I kept the revs down and rode it back the the house and put it in the garage. But it's at my in laws house and I can't get back there till this weekend to have a look.
So obviously I'm suspecting that I got the timing wrong when I put the cams back in and can't stop thinking I've bent some valves.
But would it run OK if the valves had hit the pistons? And wouldn't the noise have gone away as the valve edges got mashed off? Or at least changed to a different noise as the valves broke up and fell into the pistons?
I know the only way to check is to strip it down again and have a looksee, but any thoughts to make this long week go by?
