OK it's been a little while since I last rode my 600... But i've noticed a few things... at like 50 or so if I let go of my handle bars they shake pretty bad... also the thing RIDES STRANGE!! I mean REALLY strange... turning right feels find, but when i go left if feels like crap... the bike doesn't want to turn or feels like the front end left side dips down and wants to turn sharp... the bike just doesn't feel smooth at ALL! any ideas??? I checked the PSI was at 36 like it should... any ideas? got 8K on it, maybe time for new front?
