Interesting post on torque, I wasn’t aware that was an option, thanks. Recently I was golfing on a very hilly course up north and the cart I was using was a beat up older model Yamaha EFI that had better climbing power than any cart I have ever driven. I flipped up the seat and the first thing I noticed was that everything was filthy except for a brand new shiny primary and secondary clutch and drive belt.
I am definitely going to look into replacing the secondary clutch springs in both our Yamaha’s.
