You really need to fix this
You might want to reinstall the original intake until such time as you can afford the tuner. Running lean and thus hot can get expensive fast.
My father had an old Evinrude Norseman snowmobile. These had a pull cord starter. To make it easier, there was a compression release valve on one cylinder that you would open when starting and then close. Those valves always got worn and leaked air into the cylinder. Since that cylinder was running lean and hot these sleds always died horrible deaths with a hold burned through that same piston. So we were told after his sled left me stranded in Chequamegan National Forest.
Similarly my first car was a 1979 Ford Fairmont that was the last car of an elderly couple. Somewhere along the line they had installed a hand choke, which the dealer removed when I bought the car. They didn't seal things well, though, so I burned the valves until eventually the engine lost enough compression that it was hard to start and would frequently die. A proper job of sealing around the carburetor resolved that problem. Oh yea, and replacing all of the valves cost me a pretty penny as well.
If you see an old motorcycle with the chrome pipes turned blue and black as they come out of the cylinders, that is a sign that the engine ran lean. I don't know if it's hot enough to peel paint or burn it off of a blacked out exhaust or not.
If the bike is used, are you sure there isn't a tuner on it that you haven't found, yet?
