 | | The exhaust system supplied by Rotax is specially tuned, to provide the best performance and reliability possible, some manufacturers in adapting this exhaust system to their design have changed the tuning length of the exhaust to better fit the cosmetics of their design. |
 | | Rotax has introduced a new engine cowling for use on the 377,447, and 503 engines which directs more air to the magneto cylinder, making for a cooler running engine. |
 | | Upon closer examination it was found that the aluminum intake manifold, on the single carburetor equipped 377/447/503 had cracked in the area of the bolts used to fasten it to the cylinders or at the point where the outer half of the manifold joins to the inner half on the 503. |
