[red rocket]

Hey guys! I am going this Sunday to trade my ltr450 quad for a 03 rc with 29k on it. It has Jardine cf pipes but no powercommander. Is this a good deal and is there anything I should pay extra close attention to before taking it home? Also, if I do the flapper and soft rev mod will it still improve performance without a pc? Thanks in advance and I look foward to getting to know some of yuns.

The soft rev mod will allow the bike to rev to 10.2K RPM (the hard limit) as opposed the to the 9.2K RPM soft limit (N. American models only).
The flapper mod will not add HP, only prevent a dip in torque and HP around 4500 to 6000 RPM.
It was there to lower intake noise for EPA noise regs.
If you have a full system and possibly slip-ons, you may need a power commander to richen up or better tune the fuel ratio over stock system.
The optimum air/fuel ratio is 13.2:1 for best power.
