This bike has 35 hours on the original factory piston from when I bought the bike brand new. There are emperor racing radiator guards/brackets installed as well.

The bike runs as it should, the carb hasn�t had to be cleaned, and I haven�t fouled a spark plug (original factory spark plug) in all the time I�ve owned it.

Transmission oil changed every 15 hours

Fuel to Oil ratio was 32:1 as recommended by Yamaha

Only premium gas was used as well as yamalube 2R oil
