60 over, port and polished, head shaved, piston skirt cut, new reeds, new pipe, different front and rear sprockets...96 mph! I don't remember what it was stock.

The Yamaha Tri-Z was produced in 1985 and 1986. It was a three-wheeled all-terrain vehicle (ATV) known for its performance and sporty design. The Tri-Z was part of a competitive market during the mid-1980s, but production ceased after 1986 due to changing regulations and safety concerns regarding three-wheeled vehicles.
I've owned both and with both vehicles running good, a Honda is faster, especially the 1985 and 1986 Honda 250r's with liquid cooling. The Kawasaki Tecate was faster than both the Honda and Yamaha.
The proper fuel mixture for a Yamaha Tri-Z 250 is typically a 32:1 ratio of gasoline to two-stroke oil. This means for every 32 parts of gasoline, you should mix in 1 part of two-stroke oil. It's important to use high-quality oil designed for air-cooled two-stroke engines to ensure optimal performance and engine longevity. Always refer to the owner's manual for specific recommendations based on your model year.
The Yamaha Tri-Z, a three-wheeled all-terrain vehicle, was produced between 1983 and 1985. Approximately 16,000 units were manufactured during its production run. This model was part of Yamaha's push into the three-wheeled market, known for its performance and sporty design. Production ceased as safety regulations began to impact the viability of three-wheelers.

apparently the 85 and 86 diameter is 35mm(same as the 85 tri-z 250), earlier years are smaller diameter.
The 1985 Yamaha Tri-Z is a two-stroke engine, which requires a specific oil-to-gas ratio for proper lubrication and combustion. The recommended oil mix ratio for the 1985 Yamaha Tri-Z is typically 32:1, which means 32 parts of gasoline to 1 part of oil. It is crucial to follow this ratio precisely to ensure optimal engine performance and longevity. Failure to do so may result in engine damage or poor running conditions.
