Need some help with this one. My 2008 Tiger ABS has developed a stutter and stumble at 1/8 to 1/4 throttle opening. It occurs randomly, and I can't make it happen. It comes and goes , sometimes it will go a 100 miles and not happen, then it will happen a number of times within 5-10 miles. When it occurs. it appears to be dropping a cylinder and just running on two cylinders. I can bring it back to normal running by opening the the throttle hard. Then it will hiccup and come on like gangbusters. So far I've run a couple of different fuel injector cleaners through it, and also some HEET, thinking it my be water in my gas, but to no avail. Anybody else run into this problem, and if so, how did you solve it? Thanks for any advice.
