Help! Just replaced the chain on the bike and matched it up with the same amount of links on the original chain. I tried to give it a test ride but the chain kept skipping. What gives? Didn't have this problem with the original chain so I figured I mis-counted the chain links. So, I took of two links. Still had the problem. I took off another 2 links and the problem did not go away. The bike has approx. 1800 miles on it on the original chain was oiled regularly and cleaned. Help! This just killed my weekend.
