So what exactly is the physical difference in the cams(790, 865, Thunderbike 865)? The gearing has to be the same in order to keep the timing correct but there isn't much else you can 'adjust'. Is it the shape of the lobes, weight, or what? Inquiring minds want to know.
Yes, it's the shape of the lobes.
