You would certainely need the oil pump, exhaust front pipe, and CDI from the 200cc. I don't reccomend this as there are alot of small but detail changes between the 200 and 125cc engines. Lastly you can fit the 200cc version's top end to the 125cc engine. The KMX speedo is about 5mph overreading at 70mph+. If you tune it to 26-28bhp then you can fit a 16/48 and run it off the clock (90mph). You can run 15/48 for about 5mph more top end at the redline, and not lose much acceleration. The std 14/48 gearing tops out at 80-82mph at 10k rpm. The other modification to do to de-restricted KMX is change the gearing if you only using it on the road. Just fitting the TM30 carb should get you to around 25bhp r/w, and is worth doing on it's own. The compression ratio is 7.8:1, and this can be increased to 8.2-8.5:1 safely.ħ, have the cylinder barrel ported and tuned.Īll the above work would see around 27-28bhp r/w or more.

This is a bolt on part and is the best carb upgrade as it fits the std intake and air box connector hoses.Ħ, Have cylinder head re-profiled and skimmed.

If you don't the bike will run lean and is likely to seize! These mods will get you to 23-24bhp r/w.ĥ, Fit Mikuni TM30 carb. as the KDX200/220 item).Ĥ, Re-jet the std carb to suit the above modifications.

Broken KIPS valves won't fall into the engine, or damage the piston/bore, but if they seize in the closed position you lose all the top end power.Ī std full power/de-restricted KMX should make 20-21bhp at the rear wheel or 24bhp at the crank.įor tuning you can do the following things and more! This is what i would do:ġ, Fit a Gianelli or Big one front pipe, and a DEP silencer.Ģ, Modifiy the std Airbox lid by cutting out the silencer, and opening the entry to the same size as the inner diameter of the filter.ģ, Fit V-force reed cage, or Boyesen Rad valve. Then the drum valves, break due to the rack and pinion trying to open them. they do seize up in the cylinder over time, and or if the bike is ridden gently everywhere. If you test ride the bike now, then you should find that the bottom end power dissapears and that the power comes in quickly at around 7k.īear in mind that KIPS valves on early bikes were made of alloy. As a further check, you can disconnect the operating arm, and temporay fix the operating rod in the out position. When revving the engine in neutral, the KIPS operating arm should swing out fully at or just before 7000rpm. 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.
