BG 44K is good ****, no doubt about that.Find a shop that sales BG-44k add some to your gas tank. Just remember one can is for 20gallons. So add the proper amount to your bike. Another thing that would clean carbon from valve is to run water in small amounts in the intake while the engine is running. Or if you can get your hands on X66-p from a GM dealer thats the best stuff ever. But they dont sell it much anymore. But on the safe side if you never done the water thing or the X66-p just find the GB and add the right amount.
Tranny fluid works great on a diesel engine as its high in detergent and would clean the injectors. But today you can add a can of BG-44k and it would do a better job. At work we used to buy cases of it and would use it on every car that failed smog test besided the other repairs that were done.
And I'd love to hear what benefits are provided if any significant valve cleaning occurs.I'd love to hear from some people who really know, if fuel system cleaners really clean valves.
