MJ is 112.5, and the needle is 4FL46ĥ, The airbox lid has a bigger inlet on the 200. Assuming you have a 200cc complete engine then this is what is different to the 125.ġ, CDI unit (AFAIK the timing retard is different on the 200's)Ģ, The expansion chamber and silencer is different (bigger on the 200)ģ, The Carb is the same but the main jet, and jet needle are different. The 200cc engine is best used in it's entirety, and not with the 200cc top end fitted to a 125cc bottom end, which does work and fit, but there are lots of small differences. Hi, well first thing is get some pics of this nice KMX project you have up! The KMX200 unlike the TS200R and DT200R has a single rad, but you won't find many 200cc bikes derived from a 125 engine design, that use a single rad, due to the fact that the bigger engine capacity needs more cooling ability. On the 200 that im building, im going to replace the std Steel rad, with a custom built alloy one which should be around 30-40% more efficiant, and cool better without needing to try getting a bigger rad to fit, or a dual rad set up, which is more complex.

People have fitted fans with a manual bar mounted switch to help with this problem, and im told that it does work if a suitable set up is used. The 200 will not cope with continuous slow speed town riding, and heavy off road work in hot weather conditions IMO. It sounds like your rad is not in ideal condition, and most battered off road bikes, will have bent and damaged fins after years of use. For open road use it's fine and for a bit of town riding, providing that the cooling system is all in good condition.

They have a reputation for being less reliable due to overheating than the 125, caused by the fact that in constant slow speed and off road work, the 200 cannot get rid of enough heat quickly enough.

The KMX200 rad AFAIK is exactly the same as the 125's, and TBH the 200 has a fairly marginal cooling system for off road use too. On off road KMX's and field bikes, the stat is often removed causing more problems than it solves. Make sure that the stat is fitted and working correctly first.
