From: john firth Hello Dave, Does your 582 have the double jointed exhaust bend on it? The earlier one piece ones could set up a resonant vibration which could split the silencer and so obviously put strain on the manifold studs and flanges. I have used socket head capscrews on my manifold and with a bit of grinding the top of the head have managed to get all 8 in. You have to put two of the screws in before offering the manifold up and run them in bit at a time with a ball wrench but i am happier with the result although there is always a small amount of black oil around it which this wipes of easily with a bit of fuel on a rag, I think the gaskets are a bit porous and running rich as we do there will be some oily vapour in the exhaust. Regards, john.

I am surprised that no one has responded with the solution. I have taken Bob Robertson's (Light Engine Services) Rotax Two Stroke Service/Maintenance Course a couple of times. (It is fantastic; a must for anyone who operates a two stroke!). I had the same problem on my 503 and then on my 582. The solution is: First make sure your cylinders are on square (straight). Rotax has a straight edge tool that is to be used when torquing down the cylinders. Then use new gaskets. This alone will not fix the problem. The problem is when the new exhaust manifold heats and cools, it changes shape.. The exhaust flange faces become out of plane (not parallel) as a result of the heating and subsequent warping of the exhaust manifold. This is what causes the exhaust leak/slobbering. The answer is simply take the exhaust manifold off and plane it down parallel. The easiest way to use a belt sander and sand it down until the surfaces are all touching. You could also put some sand paper down on a flat surface like a table saw and sand the exhaust manifold flange surface by hand. A little care and common sense will yield good results. Most of the Rotax 2 strokes in our club had this problem until a few us took the course. Since then everyone has fixed the problem by doing this simple fix.
