I rejetted my 99 kdx200 with a 155 main and 45 pilot for the hot summers in PA. This weekends race is going to be 30-40 degrees. Should I throw a 158 main and 48 pilot in to play it safe? Thanks.

The easiest way to adjust the carb on the track or trail is to use the a/f screw for throttle response and main jet for plug color. I wouldn't try to change the pilot or the needle clip because the odds of loosing the clip or getting dirt in the carb are too great
Personally I would leave the 45 pilot and 155 main since it is still slightly rich for most of us and tweak the a/f screw the morning of the race for best response.
The main can be changed without removing the carb so I would leave the 155 and take a 158 with me just in case, do a quick plug chop before the race and then you wont have to guess.
Where is your needle clip, this is one thing I would change before the weekend. I usually richen the needle one clip position during the winter. There is nothing worse than trying to adjust your clip on the track ...ping, there goes another one !@#$%
