So let me preface this whole post with this:

I bought my 2010 hammer s last month with 4000 miles on it. I have owned several bikes in the past, and consider myself a fairly experienced rider. I have not, however-

Owned or ridden an EFI bike,
Claim to have any knowledge of victory tech
Owned or ridden a bike younger than 20 years old.
Ridden 6 a speed

Additionally, when I bought the hammer it had aftermarket swept exhaust and an s&s intake already installed.

So first and foremost, my biggest concern is what sounds like some pretty significant valve ticking, especially when under load and in 6th gear, I can hear it reflecting off cars that I pass, scares the hell out of me because the only time I've heard this type of noise is in vehicles that are critically low on oil/pressure

Secondly, I occasionally get a pretty sharp backfire while shifting up, it sounds cool, but if this isn't normal I'd like to know.

At low speeds, if I let off the throttle quickly I get a distinct "CHUNK" noise from the transmission. Never heard that in any other bike before.

And the O/D indicator light doesn't turn on...

I know it's a lot, but I get so anxious about stuff like this so any feedback would be greatly appreciated

Ticking noise sounds like it could be pinging. I had this issue with my Vegas under hard excel. Try a little higher octane gas if you can. If that doesn't help then your cylinders may already be carboned up so try running some Seafoam or Victory carbon cleaner through a couple of tanks of gas. This could also be caused by the bike running to lean from not being properly set up for the mods it has. The oil pressure isn't a concern on these bikes. I read somewhere that the oil pressure is around 70 psi running down the road. The "CHUNK".....get used to it, it's a Victory thing. Has to do with gearlash in the gear driven primary drive. Just the way it's designed, bullet-proof but a touch crude. The O/D light, anybody's guess. Could be a bad bulb, wiring or a bad sensor switch. Check your battery cables for clean and tight. A lot of strange electrical issues are caused by bad grounds in the electrical system.

Ticking could be pre-ignition which is solved by running premium (see owners manual) or lugging. These bikes don't like to lug so at a minimum you should try to keep it at 2600 rpm and try not to accelerate if you're turning anything less than 2600 rpm.

Backfiring is pretty common after exhaust/intake swaps and can be tuned out with a fuel controller.

The clunk when you let off the gas is normal and won't hurt anything. It's basically drivetrain slack that you'll eventually learn to overcome with proper throttle, clutching and braking.

O/D indicator? You got me, I'm not familiar with said indicator.

it is not stock so you have to find out why the mixture is not right, pre-detonation could cause piston damage if you are hearing banging of the piston. I for one have blown a hole thru a piston because of to much advanced timing and wrong octane set up. This was on my first car, a 1968 Chevy impala years ago so I am very careful now to know the difference between spark knock and piston BANG.

If you're using premium grade gasoline and still getting the pinging, I'd be curious what modifications are on the bike. I'm with the previous poster that it's entirely possible that modifications like pipes and air intake without an appropriate re-flashing of the ECU could easily cause something like that as your bike would be running too lean. And too lean means too much heat, so it's definately worth looking into.

I put in a call to the dealer that installed the pipes and intake, they claimed it's normal for vics with high flow air intakes to hiss and have that clatter noise.

I believe the pipes are victory swept pipes, and I'm sure the intake is S&S. They say they retuned the ECU but maybe not?

Also, I use 93 octane gas in all my bikes, so I dont think that's a contributing factor

Try disconnecting the O2 sensors to see if you get a change in sound and the way it runs. By doing this you will put the AFR into its backup mode because it thinks the sensors or broken or burned out. Backup mode is around the mid 13's AFR which is a good place for Vic's to run in.

Interesting, if I understand correctly, if I disconnect the O2 sensors and experience little to no change in performance, that means the ECU was never retuned after the aftermarket parts were installed? I will try this tonight

I don't know how far you are from The Vic Shop just west of Des Moines. I would get in touch with Rylan. He could probably save you some time and unnecessary worry with a quick call or email.
The biggest thing I have learned after riding my Hammer for a couple years now, is these things don't like to be putted around. I found that if I shift at about 3000 RPM's, the popping and backfiring seems to pretty much go away. If you shift at 2600, 2700 the popping seems to happen more. Drive it like a hammer, it will love you back. I agree that the transmission is loud and clunky but it is rock solid. No problems at all. You will get used to it.

Not necessarily but it will give you more information to find out if it's running too lean.

The connectors are usually 6-10" back from the sensors.
