[QUOTE="acutemp, post: 668230, member: 16367"] Rhodester, Excellent first post, it's always good to see people dive in and look to really understand how different setups can change "personality" of their bike's power delivery. Thank's for sharing your finding's as post's such as this are very helpful to other's that are trying to achive the same goal of fine tuning the jetting on their KDX's. Your #7 slide sound's like a pre-95 non air striker style slide and it won't work in your 95's carb. :ugg: I do prefer a leaner slide than the stock #5 though and the #6 that you have is a step in the right direction and is what I would work with. I wouldn't worry to much about needing a bigger main than most run, every bike is different and running a 162 main is not unheard of. If you have room to run wide open for a half a mile then I would jet on the side of safety. The carb body can tend to wear over time also which can cause the need for a bit richer jetting on some bikes. My thought's would be that the richness at 1/8 throttle that you are running into is due to having your jetting package a bit off. It sounds like a little tweaking with the crossover points of the different jetting circuit's might be needed. While going leaner on the straight section to try and clean this up you found that you needed to go to an extreme clip position to compensate when wicking open the throttle. This get's you into the taper quicker which helps when opening the throttle quickly but is to rich otherwise. Here is what I would give a try if you are up for more testing, CEL#3,4, #6 slide, 40-42 pilot, 160 main. It is a setup that is leaner in the area that you are trying to clean up. When changing from a B taper to a C taper you can usually go 1 step smaller on the main. If you have access to an Excel spreadsheet program I would highly recommend getting a copy of JD's jetting guide as it will allow you to input all of this data and map your jetting curves on a graph. This is especially helpful when working with multiple slides and needles. :thumb: Good luck it sounds like you are on the right track and with a bit more fine tuning you should have it dialed in.--Dan [/QUOTE]
