- Just picked up a used 2002 520 E/XC
- What are common performance mods engine and/or chassis for this bike
- Anyone know anything to look out for etc.
- Do guys typically run stock gearing, etc.
- Any archives I can search for this info?
Hey Al, I have a 525 exc. I've only done two things to it... 13 tooth counter sprocket and a Big Gun Lafferty exhaust. Both made a world of difference for me and my style of riding.
