Vehicle Information
Yamaha JT2MX Dirt Bike (1972)
The 1972 Yamaha JT2MX is a classic mini-enduro motorcycle, powered by a 58cc two-stroke engine. This robust engine delivered 4.5 horsepower at 7,500 RPM and 3.62 ft-lbs of torque at 5,500 RPM, featuring a 42mm x 42mm bore and stroke with a 6.4:1 compression ratio. It was equipped with a 16mm Mikuni carburetor and Yamaha's Autolube lubricating system for automatic oil delivery. For the 1972 model year, the JT2MX was offered under several designations, including the "JT2MX," "JT2 Competition," and "JT2MX Base." A "JT2M" model, a mini-motocrosser without lights, was also available. The factory color was "Competition Yellow." Compared to its 1971 predecessor, the JT1, the 1972 JT2 series incorporated mid-cycle enhancements. These included internal engine modifications for improved reliability, carburetor changes for enhanced performance, and upgraded lighting intensity. These changes represent a significant evolution for the model. FAQ:

Maintenance
| Component | Interval | Details |
| Autolube System | Before each ride or prolonged use | The Yamaha JT2MX uses an Autolube system, not a traditional oil filter. Check the Autolube tank level and top off when the oil level is low. |
| Drive Chain | Periodically | Check tension and alignment. Lubricate periodically to prevent stretching and extend service life. |
| Spark Plug | As required | Inspect, clean, or replace as required. |
| Air Filter | Monthly or every 400-800 km (or daily for hard usage) | Foam-type filter. Clean and oil at least once per month or every 400-800 km, whichever comes first. For hard usage (e.g., dirt riding), clean and oil daily. |
| Coolant | Not applicable | Air-cooled engine; no liquid coolant used. |
| Transmission Oil Level | Periodically | Check transmission oil level (includes Autolube tank). |
| Brake System and Clutch | As required | Check and adjust as required. |
| Wheels, Tires, and Spokes | Periodically | Check tire pressure, spoke tension, and runout. |
| Fittings and Fasteners | Before each trip | Tighten before each trip. |
