Could it be the valves? I know they are overdue for adjustment. The sound has been there since I got it. And it was overdue then too.

Mine was making a jingle sound. I switched over to higher octane like mid grade. Never heard sound again

It should be the tappets..! But these bikes have some ticking sound even when properly adjusted. I know this cause i had valves adjusted when i bought the bike. It had very light tickling from day one..!

Shew, I was going to log on this morning and asak this! Since my first service I have noticed some ticking, specifically when I start the bike up cold.
Relief that my bike is not going to explode.

Maybe Yamaha did it as a bad joke....

Just check the valve clearance, it's pretty easy on the TW, especially with all the good info on this forum.

Also the factory skid plate rattles at its hinge. I used a piece of stick on rubber to fix rattle

I think a minor amount of ticking is normal, You have to remember these were designed around 1980. It's better to have it tick a little then have the rockers adjusted too tight. Another thing that may make valve ticking worse is a worn bushing on the sprocket end of the cam, and/or worn rocker shafts.
