[QUOTE="James Dean, post: 80567, member: 18501"] If any 520 riders can't get enough power. here is your fix :eek: - [b]Replace the stock OBDTM#2 needle/175 main with an OCEMN#4/168 main.[/b] There will be an instant boost in your power from 1/4 throttle up. More snap at the throttle to loft your from wheel at any time. It works in the 400 also. ---------------------- The needle has more taper which requires a smaller main jet to keep the full throttle jetting unchanged. Leave the pilot (#48) and pilot screw unchanged (about 1-1.25 turns out). This is a STANDARD TAPER needle for the Keihin FCR carb. It is very close to what the YZ426 and 250F have. The stock needle simply runs extra lean in the midrange. It can be purchased from Sudco at 1-800-998-3529 or Carb Parts Warehouse or your dealer can get it from them. Have fun and Hang On! ;) James Dean [/QUOTE]
