thanks... i know but i have to go through woods, i don't need extreme trial performance, i'd like to "put on" (i don't know the english for) a 215-80-15 tires "re-builded" tha are more heavy than new tires... so my engine has only 94hp and the deep mud and comeing up steep slopes are hard situations for it.... calmini tells me that with 5th low gear and with 31" tires max speed is about 25km\h... too low for mud...
have i explaned well?
