[QUOTE="Monkeypants, post: 53043, member: 2708"] Re Oring chains sapping power- Jim Comstock, a well known engine Norton Engine builder and ex racer has a dyno in his work shop and dyno tests his many modifications. He also dyno tested the same bike run with a standard non sealed chain then immediately after with a new xring chain. The result was zero difference in the graph, not even the thickness of a line. The old Oring chains may have sucked away some extra power, but the new style Xring chains do not. 250 HP GP bikes are now all running x ring chains. If there was even 1% to be gained by using nonsealed chain, the race teams would run it. Glen [/QUOTE]
