Welcome to the forum. Hopefully all is good with the one you picked up in terms of electronics, sensors, clutch, tranny, etc. Whatever you do, don't put oversized tires on this model. The clutch can't handle it l, and when the clutch starts slipping, the computer control for the tranny doesn't know how to handle that.

Thanks for the Welcome. I got a set of 25x8x12 and 25x10x12 for it. Would you consider that oversized?

Might consider just changing the fuel line and spark plug. You may be on top of this but don't forget the engine oil needs to be wet clutch approved or JASO

Those sizes are considered one size oversize. Which specific brand and model did you go with? If they're not super heavy ones you'll probably be ok. Others have run them in the past with success. Just don't spend a lot of time at really low speeds where the clutch isn't fully engaged (4~5 mph or less).

As far a oil change, I went with the Honda GN4 10W 40. And the tires are the MAXXIS MU19 & MU20 on ITP steel rims.

Mobil 1 4T is the best oil I found it's a full synthetic and well lubricate and flow better at lower temps. Aso for your tire problem I recommend a radial tire STI Black Diamonds are a great choice, they don't tear up ground and ride hard like a tractor tire, they are stronger and better all around. If you ask anyone here they will tell you what I'm saying. I hope to get a set soon the replace my tractor like tires and improve the ride.
