Is this what a bad timing chain looks like?

Ok, I van upgrade to deal cogs, heavy duty for a total of $99 bucks complete. Do I really need too because I have not changed compression? No, but will it last longer? More reliable?

Tming Chain and gears dont raise or lower your compression. They keep your camshaft and crankshaft in time with each other which ultimately keeps your valves and reluctor (tone wheel) in time. So you dont want to jump time. It will shut you down instantly without warning and can possibly do major or fatal engine damage.

...also being loose, your timing is inaccurate during engine RPM changes... Especially when you lift off the throttle after accelerating.

Change it! Or maybe you like tearing it down. If so, maybe next time you can also change a few pistons if it drops a valve or two when it breaks...

factory chains are not that tight from day 1...normal

There is a reason to change gears, they wear as the chain stretches. Every other time I would change a chain on my motorcycle, I would also change the sprockets. Same principal. I know it is not the nicest thing to hear, but I speak from experience with timing chains: Don't skimp. The money you spend on the chains and gears is very well worth it. Good Luck.

If you change the gears, good luck getting that lower one off. Mine wasn't coming off without cutting it off with a torch so I left it and changed the upper gear and chain. Not the perfect solution but they didn't seem worn too much anyway. I was just doing it for maintenance.
