i'm running a ddk needle, and was contemplating a switch to cck or ccj - jetting is perfect at 60 degrees plus, but i get a hesitation/lack of power at 40-60 degrees 0-1/4 throttle, and when i really whack the throttle. for example dead engine start - wot - 2nd gear. when i kick it at 60 degrees + it snaps to life instantly and i get a killer start. when below 60 degrees it hesitates then snaps to life, which can be unpredictable (giant wheelie...) i'd prefer to not rejet, and just use a needle that will work better all over... this weekend i started at 10am and it was cold (30 degrees) and bike was frustrating/hesitant/lack of power when i really needed it on hill climb bottoms and at the start....once the temperature rose, jetting was right on.
here's the problem:
i run 2 series - 1 starts at 10am, and 1 starts at noon. the temperature differential is drastic enough that my on the edge jetting is just lean enough to be weak at the earlier in the day temperatures... if i change my pilot from 42 to 45 to compensate it's too rich when it's hotter.
i need to get every bit of hp i can outta the 200. swapping in a 300 motor is my next step, but i'd much rather have a 200 that would make my life easier later in the races... but i think the 250 motor is more like the 200 motor, and would be better for my style (snappy and on the pipe as much as possible...i can't really lug a 200
i don't like to run in the lower rev ranges until it gets technical..) the 450 4t's have a big advantage over me in the big straights...
on another note : i know it's a long race, and the start is just a small portion of a race, but i'll tell you what, where else can you get past your whole class and not fight for position all day than having a giant holeshot? you don't get tangled up when you enter the woods first and alone i'm not as experienced, smooth, and as fast as the dudes in my class (they all have 30+ years racing experience on me..the 40+ classes have a lot of experience..many times guys in my class finish top 10 overall) i need all the help i can get
