Yamaha Quiet Tech Spark Arrestor
Did some wrenching on the ride this morning, and since I had to pull the skid plate to drain the oil, I decided to remove the problem causing spark arrestor while I had easy access. Below are a couple pictures. It came off very easy with an Allen wrench. After 141 hours on the cart it was clearly starting to clog up and would have definitely started to caused some performance problems in the not to distant future. After removing it, I noticed a little bit more responsiveness and a negligible difference in cart noise. The cart might have been slightly louder when accelerating at low speeds, but there was absolutely no sound difference once the cart reached cruising speed.
I would highly recommend fellow Quiet Tech owners remove these devices from their carts before performance issues rear their ugly heads.
