Owner Experiences & Common Issues
Carburetor maintenance

TC 125 - Buying & Maintenance Guide
What to check before buying
When inspecting a used 2021 Husqvarna TC 125, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained TC 125 should fire up cleanly and settle to a smooth idle within a few seconds.
Oil and filter changes
Regular oil changes are the single most important maintenance task on any TC 125. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. The sump holds 0.90 litres, so budget for that volume of quality motorcycle-specific engine oil. Always use the correct viscosity grade as specified in the owner's manual.
Carburetor upkeep
Keep the carburetors clean and free of deposits. If the TC 125 has been stored, strip and clean the carb float bowls before attempting to start it. Pilot jets are the first to block and the last to be checked - always include them in any carb rebuild.
