My blaster had the oil injection removed. It always smoked on wot. So I took the carb apart, saw the stock 230 jet and put my 240 in. Cleaned the slide, put it back together. Pulled the spark plug and it was pretty dirty, so I changed that. Now it runs great. No more smoke on wot. I opened the muffler and it had a coat of oil inside, is that normal? Also removed the tube on the airbox lid and got rid of tors. So did I do good?
