Haven't even rode the new bike yet, been raining and snowing.. Noticed my forks were twisted in the clamps, needed to lube the steering bearings anyway.. Decided why not lube the swing arm and linkage while its raining.. noticed no master link in the chain and was thinking maybe its a good time for a sprocket and chain change.. Anyone change their rear ratio? I like a 52 on my 400, wonder if that is too low for the 450? I ride single track, tight woods, slow and steep.. Thanks and happy new year..
