unlike the Pacific Coast where the heat exits out the bottom or the two side vents. My stock suspension sucks the big one. I need some shocks and front springs bad.
The higher MPGs in the mountains is due to the lower air resistance from the thinner air. I've experienced the same even in a car. Once you get above 5,000 or 6,000 feet, it becomes noticeable.
Are these bikes reliable even at 20+ years old? Assuming they have been taken care of.
