yeah but someone on the h22a.org forums was talking about a specific thing to do when you remove your counter balance belt, and I forgot what it was, it was to make it to where you did not have the belt, nor the vibration. But if you have excessive vibration at idle w/o the counter balance belt, wont the engine shake itself loose? its on there for a reason, however, the reason may be most people are jus anal about having a smooth car....I have to research it more.....
