I use an old garmin etrex but have never offloaded any files. Just let the track log run till it’s full and then writes over itself. Keeps your most recent trails up on the screen.
Been riding since I was old enough to pull start our old Honda big rid trike. Dad gave me the 92 TRX300 to fix up and get running. Did some searches and found this place. Nice to find like minded people
I usually run factory oil in my bikes but I have tried Castrol motorcycle oil and shell rotella with decent results. Just make sure it’s rated for your quad
