Sputtering up top

Bought a 10 off someone on Craigslist. 26xx miles and it runs fairly well but unless it's really warm itll sputter and backfire around 9-10k rpm in higher gears.

It feels like theres no power if I approach full throttle, I have to gradually speed up to get to 50 plus sometimes.

Idk how long it sat but I put in exxon gas and seafood and over the 400 miles put on it through three consecutive weekends it's running a bit bitter but I worry i need a full carb clean or rebuild.

Suggestions? I'm giving it an oil change this weekend

Oh and there's a squeaking noise coming from the front above 30mph. Thoughts?

Well there's your problem. Gas and seafood!
Take out the scales and crustaceans it might run better.

Seriously. Check the cleanliness of the airfilter and lube the front axle, speedo gears and wheel bearings. While you're at it clean the brake rotors and calipers.
