Hello everyone, I recently purchased a 2005 black and grey Hayabusa. This is the first bike I’ve owned in 3 years. I was into racing and building turbo charged cars for a long time but got bored and got the bike for a change of pace…I have the 16/42 sprockets, PCIII usb, BMC race filter and just installed the DJ wideband commander. This is a awsome site and I hope to learn alot.
