Hi all, I'm new to the snow mobile engine world. I've been toying around with single cylinder two-strokes for years. But I'm not familiar with the twins at all. I live in So. Cal. And snow is not that common. I bought this 85 ski-doo formula plus type 537 engine on line. This power plant is to be installed into an odyssey and I need to know the best light to mid performance mods to be done to the motor. The motor came with the stock 2 into 1 pipe; pair of 38mm round slide carburetors, all electronics- gauges wiring harness, etc… it also came with the stock driven clutch and a comet 102c drive unit. The bore is a standard bore and pistons/ heads are in good shape (no pitting, carbon build up, etc.) Any help would be greatly appreciated.
