2004 speed trip- I noticed that the front forks have a lot of sag(2inches) this could have been from being tied down to long in moving truck or to many wheelies i do not ride bike much but have noticed this when front end was lifted off ground the last time. is this something someone has seen before. will a pair of 2001 forks work??(on ebay) are the inside spings or cartrage? any help would be great thanx.
