It is small, but my son is also 6' tall. It's about 200 pounds wet.

It's got a decent frame, inverted forks, and sticky tires. On the right road, with the right rider, it would be hard to keep up with.

For those who are interested there is a number of videos and articles on tuning and porting 2 stroke engines. The pdf of Gordon Jennings's tuning guide is perhaps the most cited.

Sometimes it's quite surprising how a rather simple tuning and porting can lead to a great improvement to the performance of a 2-stroke.

Limited availability of replacement parts has been a concern here in Brazil too. I have already seen some Yamaha DT 180's retrofitted with Honda CG 125 engines and the owner of one of those told me his main motivation for that move was exactly this.

Change your final drive ratio by putting on a larger rear sprocket. Less top speed, and probably worse gas mileage, but you'll get more acceleration.

I have a 2010 YZ250. I love 2 strokes. Sound smell and simplicity.
I also have a 2 stroke powered snowmobile. A 580 ski doo double.
