elevation change questions
Soon I am planning to ride my motorized bicycle on a mountain trail. Where I live the elevation is 330 ft above sea level. The trail head I plan to ride on is 1500 ft and I might ride up as far as 4000 ft above sea level. How is this going to affect my fuel ratio? I think it will make it richer the higher I go but I am not sure. Do you guys think that these elevation changes will make a big difference?
