These are photos of 2 different intake camshafts I bought for my 1985 VF750F in the last while. The one in the background with a sprocket attached is a used one said to be from a 1983, and the one in the foreground is a new one I found with part # 04101-mb2-000 on its packaging.
Front intake camshaft removed. I used the flashlight on the right to remove the buckets. It is telescopic with a gooseneck and a magnetic ring around the lense.
