More power for your 'Busa, Sir?

NEED MORE power from your Hayabusa? Yoshimura has just launched a new ST-1 camshaft set, suitable for the 2008 onwards 1300cc superblaster.

When used in conjunction with Yoshimura’s JMCA 4-2-1-2 full exhaust system, and without any fuel injection adjustment, peak horsepower with the cams fitted is 175bhp – 3bhp over the same set up with stock cams. Torque output is improved at higher rpm, also.

Yoshimura say, the addition of a race-style open exhaust plus tailored fuel mapping will obviously give considerable gains over stock.
