Ok Guys, I am going to ride limited soft core MX and trail ride. I weigh 230 and want to do the mods I need to make the bike safe on the track. I have been told by the local suspension guy to do the front and rear vales and springs and he will help me set the sag and such- $575.00 Is this good or bad ? Should I do something else. I also have a heavy GYTR flywheel I am installing very soon.
