First off, I was wondering how often people replace their drive chains around here. In the manual it says every 7.5 hours (of racing) or something! Since this chain has about 75 hours on it, I was thinking it might be time to get a new one for next year. I think the gold chains look sweet, but do they have any advantages? I think I heard they are stronger and don't rust or something. And finally, what about chain length? The manual says it is a 120 link 420 chain. Besides 10 links, what makes the 130 link (for sale here on CRFSONLY) different/better?
