Hi to all I'm new here n to riding blaster. I didn't know if there's an area to introduce my self and it took me a minute to figured how to post lol. Ok I just bought an 03 blaster in good conditions with oil injection remove. I just bought new tires to take those huge looking tires,I just bought a shearer pipe kit, uni filter, jet kit and lowering kit for front and back. I have read for days about blaster and jetting a lot of different opinions and info. But I'm going the spark plug test route. But I have read about altitude and is confusing the crap out of me. I live in Florida, and where I ride is dusty and it gets between 80-108 degrees on the upcoming month. What jet size should I start w. 310? And can I still ride with lit is a k&n lit that was already in it. Thanks in advance.....
