Hayabusa Gen 1 Camshaft Pair Regrind In:248deg/9.30mm lift, Ex:234deg/8.20mm lift
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.
Please see instruction sheets for information regarding the camshafts, their installation & running in.
