Hayabusa Camshafts & Valve train components

The first upgrade to the standard busa cams involve regrinding the original cams to new profiles, for this upgrade the customers cams are required. These are a nice upgrade over the standard cams, giving an increase in torque & horsepower. This is the largest profile that is achievable as a regrind using standard cams. It still makes use of the standard springs & caps, which are extremely good.

The next profile is achieved with two standard inlet cams (supplied by customer), which are then reground to a profile which is larger than can be ground onto the original exhaust camshaft. This gives a further increase in horsepower yet still retaining standard springs & cams. If you do not have another inlet cam, we can produce a steel billet, this is at increased cost.

We have been working on improving the airflow of the cylinder head and for our latest development, we have designed a new valve made of composite materials to cope with higher rpm applications & higher lift camshafts. The valves are +1mm for the inlet and exhaust; 34mm inlet and 28.5mm exhaust. These have been made in large quantities which has enabled us to significantly reduce the cost, yet maintain the high quality.
