hey guys, i recently bought an '05 crf250r and its been great to me. I've only put maybe 5-6 hours on it since I've had it. however, I just started it today, for the 1st time in about a week, and in no more than 20 seconds, honestly, quite a bit of white smoke was coming from the where the muffler bolts on to the exhaust pipe. The exhaust is still blowing good out the muffler, but the smoke isn't noticeable out of the back. also, a bit of white smoke is coming from what I believe is the decompression valve? (little hole on the right side of the head) Could running it too rich cause these areas to smoke? If so, Would turning the fuel screw underneath the carb clockwise help me? Thanks for any info.
