I have a 1910 Harely that I love to ride. Problem is I live in a hilly area. I can ride the bike all over town, but the hill up to my house (about an 8% grade 3/4" mile long) it makes it about half way and runs out of power and I have to push the 300 lb bike the rest of the way up, which I am not fond of ( or have my wife get me, which she is not fond of). There are lots of other inclines I ride on with no problems. It slows down on some but chugs right along. Are there any tricks to boost the power?
