Hey, First post here. I saw you guys and saw yall seem up to snuff with these rhinos. Let me run this by you, My 04' 660 is topping out at maybe 25mph. So far i have tried every trick I have found on this forum. Its not the backup switch or a gummed up primary sheave. I cleaned it and grounded the switch The belt is still in spec at 1.22''. Any ideas???
