It might be those air filters, I heard the stock ones are the best!
You have a PCIII what? PCIIIr or PCIIIUSB?My 2001 RC-51 has a power commander III and I just put k&n filters on and feel that I need to remap the power commander as it seems to not run as good as it did before. My question is do I need to buy a cord from dynojet to hook from my laptop to my power commander or is it a normal usb connection? Thanks for the help as the more I ride the bike the more I am happy with it-just need to fix the small issues.
Maybe for an RC51, but this does not necessarily apply across the board.
A UK magazine last year compared several air filter brands on a CBR1000RR and found K&N's flow more air than stock paper.
They weren't the top dog, but were at the upper end.
The top performing air filter was the BMC Race filter.
Second was the regular BMC filter.
The BMC Race filter flowed more air due to less amount of filter material.
Good for racing, maybe not so good for street.
