The KIPS valve is not restricted on any KMX after 97, im sure of that! Early ones may have been, but you can check for this by taking off the RHS cover and checking that it has full movement out, which is the high rpm position. It sounds really great IMO, and with a DEP silencer, it makes the bike sound far more MX like! This pipe is supposed to increase power by around 10% over std, it's louder and much lighter than the std front pipe.Ģ, Gianelli, The Gianelli expansion chamber is supposed to perform very well, and it seems to add more top end power from 7k upwards, and has a bit more overrev, past 9000rpm, before the power drops off.
( restrictor is the same set up as the NSR, in that it's a metal tube with 3 spot welds, situated in the front pipe).ġ, Big One (formally Fresco). There are two choices of performance expansion chamber, in addition to the de-restricted std item.
Having said that on the KMX200 the std silencer is quite restrictive.ĭEP don't make an expansion chamber for the KMX. Ok, well DEP do make a decent silencer, and it is worth having, as much for the improved sound and throttle response, more so that bhp.
