So I’m dumb and put the oil filter in backwards and to make things worse and even dumber move I rode it for 50 miles!! Like that.
It turned off on me many times and now I put the oil filter in correctly and put 10w-40 because it’s thicker.

I don’t know what to do now.
I’ll have to get it rebuild and idk if I can do that, since it is my daily driver and I work 25 miles away.

i can replace the whole engine but I’ll need to take it to the shop since I won’t be able to do that, one guy said he’ll charge me 1200 for an engine swap to a 300cc cbr engine. I don’t trust that guy though.
I’ll need to check another spot.

last option is to sell the bike how it is right now and see how much I can get for it.

what would happen if I keep riding it like this? The oil level is good now and the oil filter is in the correct position.

thank you if you read this far, and yes those were foolish moves, i learned and now I want to do what I can to save money.

I'm pretty sure what you're hearing is rod knock. It gets worse over time and will eventually need a rebuild. You MAY be able to do it yourself, I believe the tools are rachet, sockets, torque wrench, and piston ring clamp plus a manual and tools to remove the coolant plumbing.
You might get a good chunk of money selling it as a beater/trainer bike. If you are a good guy, you'll let the buyer know what happened. Many sellers won't.

Don't feel bad. Many owners have done the same thing.

Good advice by JKV.

If you get into checking the internal parts of machines an endoscope will be your best friend. They're cheap, like sub $20 cheap and many of them have attachments. I thought I would use mine once or twice but I find I use it regularly for things like finding things dropped down the drain, looking in walls, looking in spark plug holes for cylinder wear, and looking under cabinets for dropped parts (which I do often).

ANYONE can do this by following instructions in manual. That's how amateur mechanics LEARN to become better amateur mechanics. If you never learn anything new, how will you get better? Manual is excellent and can guide brand-new mechanics who've never done any of this work.

Agreed.
A mechanic in a shop is doing the same exact thing their first time, too, by looking over a manual to see how it's properly done. It goes without saying that it's always better to learn on a cheap, already broken motorcycle than an expensive one.

I don't know how many times I've put off a repair thinking I would destroy it then understanding afterwards how easy it was to do. I have undoubtedly saved Tens of thousands of dollars by doing my own work. There are some jobs that will require special and prohibitively expensive tools to repair and those are the jobs I hand over to a certified mechanic.

Don't forget that these machines were engineered and built in a way that could be repaired by less-than-brilliant people... except maybe those that put their filters on backwards

Yeah, that's really bad. Replace the top end. Shouldn't be too expensive if you buy used.

What about cleaning it up ? Like sanding out the scratches? What do you think about that

You can't safely take more metal away, it's a moving part with a precise fit. Even if milled smooth the cam will just scour and bang against the journals until it destroys itself. You might smooth and polish it but you'll probably not get more than 500 miles out of it. Bits of metal will continue to flake off and enter other parts of the engine. I'm pretty sure it's heated itself super hot and annealed itself as it cooled.

How does the piston and cylinder look? If it's smooth and moving freely, it's just the cylinder head. I looked on ebay and I don't see one available. I'm guessing one can be found at around $50 if you're patient enough to wait for one to pop up. If it's an emergency and money is no object you could just go with a whole used engine. Poke around in there a little more, maybe remove the cylinders and see if there is more damage before you begin buying parts. Usually you can get an engine rebuild kit with all the gaskets but I don't seem to see one. You might look into seeing if one is available.
