YZF1000 Cam Chain and Tensioner Rattle

[Twisted2004]

Finally got round to having a look at my cam chain and tensioner on my YZF1000R Thunderace (1998 45k miles)

I started today. The bike is currently in bits.

I removed the cam chain tensioner first. It didnt look too bad. But I can see some wear on the teeth of the plunger.

I pulled off the valve cover to check the front guide. Again doesnt look too bad. No cracking or significant damage. Although there are some grooves in the guide.

I also checked the cam chain for slackness. There seems to be some play in the chain.

I have included videos and pics.

Does the cam chain look stretched and need replacing?

Does the cam chain tensioner needs replacing?

Guides are worn and need replacing?

Or go and buy a new bike?

Let me know what you think. Thanks again in advance!
