I've been thinking about getting a Venus II with an OS 120 AX and mounting it inverted with a Bisson muffler. Has anyone tried this setup? How will being inverted affect the performance of the engine? How well will it all fit under the cowl? I'd appreciate any thoughts anyone has about this.
Thanks.

Since the Bisson inverted muffler for the 1.20AX actually mounts on the side of the engine, it will not fit under the cowl and will more than likely require a large opening to clear the muffler itself. On page 10 there is a picture of a Saito 1.25 inverted with a Slimline Pitts muffler and even it required an opening on the side just to clear the piping to the muffler, mounted behind the motor. Now imagine that Bisson muffler mounted where that plumbing is. I was thinking about the Bisson myself until I saw what it would look like. I haven't made up my mind about whether to go with the Saito 1.25 or the O.S. 1.20AX, mounted at an angle to point the exhaust down the channel.
