you would probably have to get a DI 2 stroke (with the opti as an exception) for it not to sound like a top fuel dragster. You should hear a merc race 2.5 outboard engine. That thing sounds wicked. Its hard to describe.

Like above posters stated, normal. It's just the nature of a 2 stroker and the way they breath. Also the lack of oil in the bearings adds to it alot. Remember that a 2 stroker simply oils the bearings by the residual oil in the crankcase that comes out of the fuel whereas a car engine has oil pressure in between the bearings and the crankshaft. 2 stroke engines bearings are designed to last, but not neccesarily to be quiet doing it. My old 81 150 MERC sounds like a top fueler with a mis-fire when it idles.

My father in law has a 112 Johnson and it sounds like a sewing machine at idle.
