I am going from a 49 tooth rear sprocket to a 47 tooth and wondered if it would be better to shorten the chain or just push the axle back to make up for the difference? I have always heard shortening the wheelbase can help the bike turn better but I wanted to see if anyone on here had some real world experience with either of these options. The bike by the way is an 03 YZ450F with 4 oz. Dr. D flywheel weight and complete Dr. D exhaust. I feel on the track I mainly ride that 2nd doesn't give me enough speed to clear some jumps but 3rd lugs a bit and I have to downshift in the air to get ready to get back on the gas. I would rather just have a longer 2nd gear which is why I am going down rather than up! Thanks.
