Yep.

Fun little bike.

I had a DT100 as a kid. I thought it was a 5-speed?

Before you fill up with straight gas, check the oil line from the tank to the pump and the pump to the carb. Many people bypass the oil injection and switch to pre-mix. Yamaha uses plastic gears in their oil pumps and are prone to failure.

I've had bikes and PWC's with both set-ups. I don't want to jinx anything but I see no problem with the stock set-up.
