I know its a yamaha but the carb works the same. I have just rebuild the top end in my wolvy, I bored it 20 over and put in a 88 grind web cam shaft. It already had a k&n air filter, dyno jet kit with the 155 main jet, and a supertrapp ids2. the question is that now the wolvy has NO low end and NO mid range just has all top end, and when i say no low end and no mid range i mean NONE had more stock with the big tires. i check the spark plug and it was bright white, do i need to put a bigger main jet or what? I need help bad
