[QUOTE="David Trustrum, post: 165011, member: 21529"] The LHS works in conjunction with the powervalves. The main function of the powervalves is to expose more exhaust port at higher revs & close off port at lower revs preventing loss of unburnt fuel when the port would otherwise be open too long & fuel/air mix would escape. When the engine is in a favourable rev range, the pipe is providing useful suction & supercharging wave effects, but out of this range these same waves are detrimental. The chamber is opened to disrupt the effect of the returning waves when they aren’t favourable (ie at lower revs). There is no emergency that requires a cigarette. The valves are a wonder of engineering. Sadly if you don’t take them apart to clean them they will gunk up, seize & strip the gears on the top. [/QUOTE]
