In a discussion with Bob Z we came up with the idea of eliminating the 1/2 ounce exhaust tube on my Saito 62. Bob made me a threaded aluminum adaptor to replace the steel pipe that comes with the engine. This is so cool I had to share it.. It puts the muffler closer to the engine and in the case of an unplanned hard landing the nipple will break instead of the pipe breaking out a chunk of that expensive head. Bob is thinking about offering a few accessories for four strokes and this might be one of his offerings.
