The following information is from Ron Wood Racing:
Rotax Camshafts (Nockenwelle)
660 cam, 7.9mm lift/225 degree duration. The stock"lawn and garden" cam.
670 cam, 8.9mm lift/261 degree duration.
675 cam 9.65mm lift/297 degree duration (Intake), 9.56mm lift/285 degree duration (Exhaust)
805 cam 9.60mm lift/248 degree duration.
860 cam 10.55mm lift/292 degree duration.
Wood Racing recommends either the 675 or 860 camshaft for good performance street motorads. Has anyone on the forum tried this? Helps performance? Current setup A2 with Bing vergaser.
Danke, Donny
