So I took my 85' spree out that i just got, which hasn't been rode in ten years, and all of the sudden it will not climb any hills and goes into really high revs and then just bogs down and won't move up the hill. Also top speed on flat ground is reduced. The problem gets worse the more I ride. Here is what i think it is and you guys tell me if you think i am right.
I think the belt is worn and slipping. When i first start out the belt and pulley system is cool and so the belt grips, but the more i ride it the hotter the belt becomes and it stretches and slips etc. That would explain why i can't climb hills and experience reduced power. However, i don't know how loose the belt should be. I took off the pulley/belt cover and with the belt still on i can squeeze the top and bottom of the belt together. Is that too loose? The belt doesn't look too worn, but it has sat for ten years. If it is not the belt what else could it be? Thanks guys.
Does this sound right to you?
