I am looking at buying a 95 Trail Blazer. My only concern is that it is a two stroke and past experience has been that when you start riding in areas with large elevation changes that they become tempermental. A lot of the areas I ride in have large elevation changes generally from about 4,500 to 10,000. Can anyone tell me how tempermental the Polaris two strokes are? Has anyone ever road thier two strokes on the Paiute ATV Trails in Utah? What was your experience with the performance of the motor? Any help would be greatly appreciated.
