<p>A heat riser valve for an internal combustion engine is carried on a saddle and U-bolt clamp which is conformable to and directly mounted at a readily accessible location on the thin wall exhaust pipe leading from the engine. The saddle and the exhaust pipe include coinciding valve receiving slots for admitting the valve plate of the heat riser valve. The clamp trues the exhaust pipe diameter to permit minimum diametral clearance between the valve plate and the inner diameter of the exhaust pipe.</p> |
