On a 06 WR450, the factory manual states to raise the bike on a stand, measure from the chain guide screw to the middle point of the chain. Roughly 1.9” to 2.3” of slack should be obtained. I set mine to 2” and found the chain to be very tight once I sat on the bike. I’m clocking in at 190#’s so I don’t think it was my weight but the chain seemed very tight to me. It makes me wonder how it would be if jumped like this. Anyone have a trick for setting chain tension? I don’t believe the manual to be correct. I must have measured it 4 times, just as the book states to do. I does not seem correct to me. Thanks.
