Engine braking on any premix 2 stroke that you have just had flat out for a few minutes is crazy. Firstly the motor is nice and hot and needing lots of lubrication and cooling both of which are supplied by the fuel/air mix. If you try and engine brake from high speed you are cutting off the lubrication and cooling when the cylinder, piston, rings, big and little ends need it most. It's even worse if you are riding at sea level (like on the beach) because the bike is already running lean. If you want to dual sport your premix 2 stroke, be kind to it, blip the throttle to lubricate it on the downshifts and get it stopped ASAP on the brakes. You can also have your idle set just a bit higher than usual to keep it lubricated when you are off the gas. You cannot compare it to a Yamaha RD or any other road bike, the motors are simply designed for different things. Nor can you compare it to a big bore 2 stroke that will do just about anything and still ask for more of whatever you can give it.SS109 said:I have heard mention that the KDX200 is not a good candidate for dual sporting. Supposedly holding it at high speed while street riding is potentially lethal on the engine when you let off the throttle and engine brake it. Right?
Please do go into details. What mods did you do?adam728 said:...After mods mine put up a respectable 81.2 mph on GPS...
Kurt Franz said:Also, I am skeptical about engine braking after long sustained high speeds and the engine seizing as I have never seen it happen and I have seen many guys abusing their 2 stroke bikes in this matter. That is your call - but I engine brake just like I would on a 4 stroke with no ill effects.
Take most of the stuff you read on these forums with a grain of salt - as some of the people posting are just regurgitating stuff they have previously read and want to come across as knowing something - when actually they know very little and just spend time buying worthless accessories for their bikes and posting about the next mods, admiring their spotless bikes, and riding very little.
Take the KDX out on the highway along with a bottle of Yamalube R and have at it - and come back with the real world results.....lets have some more valuable real life information. I think you will find that it is capable on the road and well worth the ride when you arrive at the trail head.
