The 300 is a solid bike, although it doesn't have the bottom end (obviously) that the 380 does. Both are wheelspin kings - it's all about throttle control. Dad went through both before settling on a 450EXC. FWIW, he wanted the 380 back after he got the 300, but he's a pretty good sized young 'un. He said a flywheel weight and a couple of extra base gaskets to lower the compression on the 380 and it would have been "right". He also had some jetting issues on his 380 and had to run 50/50 race/pump gas to eliminate bottom-end blubber. Once it was dialed in though it was a beast. One thing he said he liked about the 300 was that in 3rd gear, you could go from walking speed to haulin' without shifting - great in the woods. Now that I've thoroughly confused you I'll hush ;)
