I just picked up an 03 YZ450F. The thing is awesome, and the guy I bought it from raced it and worked at shop and has it dialed in ..Its has a complete pro-pilot-tuned suspension, but he was 180 and I'm 290 with gear..... I haven't been to englishtown yet, but plan on going this weekend to brush up on my skills....The question is, can I, should I, do anything to the suspension? I'm used to ride when I was younger=lighter , but it was all trail/woods riding with very limited MX time.... Any ideas.. BTW...this place rocks. Joe.
