Last year I bought this 1998 XC from a friend of my dads who never rode it. It had around 2,000 miles on it and is in immaculate shape. All shocks had just been rebuilt and it moved pretty good. I then put cheater heads on it, an older slp silencer thats got more of a deeper rumble to it, V Force 3 reeds, and an aftermarket clutch kit. This fall I built my own 4" riser and put that on keeping the stock bars. After that I put some pwermadd handguards on and now am thinking of putting a newer suspension in either keeping it 121" or going to 136" after riding this weekend in the powder. I am going to have this sled for a while and would like a better ride. Should i put in an edge, M-10 or suspension out of a pro x? any input and thought are greatly appreciated! thanks in advance.
