Modern Buddy

Bought my Buddy 125 used a few months ago, she's approaching 7k miles now. I didn't get the impression the previous owner did anything but regular oil changes. What should be done at 7k? Belt change? Carb clean? Tires? Other? She runs fine, no problems so far, having a blast on her. Like to keep it that way. I am NOT a DIY, but hubby and sons can handle anything that needs to be done. Also, is it better to get a belt from a dealer or order online?

At 7K, with only oil changes done before, you probably need:
Transmission maintenance: clean it out (especially getting dust out of clutch and variator), check rollers for wear/replace, check belt/replace, check clutch bell for glazing; check clutch shoes for wear

Engine oil and gear oil change. New engine oil filter.

Clean or replace air filter.

Valve check (gaps @ .08mm).

If the rear tire is the original one, there's a good chance it needs replacement by 7K.

Check brakes, fluid level for disc, pads for the rear.

I buy some heavy duty parts online but all my regular maintenance stuff comes from my local dealer. You might be able to save a couple bucks buying online, but dealers need local support!

Also, recommend avoiding kevlar belts and going with rubber replacement for OEM. Kevlar might last a bit longer, but they shred when worn out, which can damage the transmission.
