I have recently gotten my first dirtbike. It is an 86 kdx 200cc 2 stroke. The only things that I have bought for the $300 bike are a new dg pipe, silencer, gastank and that little circle thing with all the magnets on the inside that goes over the coil.
Anyway, My bike is not running so hot after I made these mods. The plug is always wet. I tried with the advice of a friend turning the screw on the carb out 3 full turns. I also tried moving the clip, on the carb, 2 different times down a notch towards the middle of the five notches. It did help by moving the clip down two. It is currently in the middle.
It seems as if the bike was running too lean and hot when I had turned the adjustment screw on the carb to 3 full turns from the bottom, but it was real fast. I ended up melting the silencer right off the bike. Like I said I am pretty new. I am running between 40:1 - 50:1. My friends said it is better to run with too much oil than not enough. I have tried b8es and b9es plugs. I think the bike is getting too much gas, from the wet plugs, and that the adjustment screw on the carb should be at 1/2 to 3/4 from the bottom.
Do you think I need to change my main jet? Should I go with a smaller one and how about the pilot jet? Do I need to adjust that one smaller too? How much smaller on both of the jets should i go. As far as I know the jets that are in it are stock. I finally got a second silencer and I am ready to start trying again. I really would appreciate your help and ideas.
