Abstract: An exhaust system provides an oxygen sensor within a balance tube for use with a marine engine. The balance tube is configured to protect the oxygen sensor from water that infiltrates the exhaust system. The exhaust system further provides a mounting system configured to attach to an engine such that an axial load placed on the exhaust system.

Abstract: A go-cart having a chassis including a support frame, a first wheel assembly and a second wheel assembly. Each of the first and second wheel assemblies is mounted to the support frame such that the wheel assembly can pivot about its connection to the support frame. A first load transfer member is connected between the first wheel assembly and a second side member of the support frame, while a second load transfer member is connected between the second wheel assembly and the first side member of the support frame. During cornering, an upward load force applied to the outside, first wheel assembly is transferred through the first load transfer member to urge the second side member of the support frame downward relative to the first side member. At the same time, the upward load force is transferred from the first side member to the second wheel assembly to pivot the second wheel assembly downward.
