Greentored 3,201 #26 Posted October 9, 2023 (edited) Just gonna throw this very general rule of thumb out there for you pulley swappers: A 1:1 pulley ratio will give you ABOUT 10mph, assuming 3600rpm engine and standard 23" tires. Take particular note of 'about'- this is a VERY general number you can go by. I dont wanna hear 'green is wrong, mine only runs 9.2' ...and FWIW- the transmissions hold up just fine well into the 25mph range..... and often above that.....
