Hi Ben, thank you for your reply. It's pretty easy to understand why the sound would be different. I am sure it's a very complicated mix of vibrations within the engine, coming from various sources, that result in the vibration you feel at the handlebars. Somehow the different geometry of the replaced camshaft affected how all these forces work together, and the result is you feel less vibration. I was hoping for a good technical explanation, but I understand if you don't have one. There's a lot of really sharp people who visit this forum, and maybe one of them will take the time to post a good explanation. I would really like to know how our bikes would run (increased hp, less vibration?) if the cam lobes were the same for all cylinders. Good luck with your experimentation, and please keep us informed of your results.
