I have a 1997 Suzuki DT150 EFI that I have finally determine has scale accumulation in the power head water passages which has partially restricted the flow through the port head and causes an intermitent over heat alarm. What is your opinion of Salt-A-Way or Salt-X for getting rid of salt accumulation inside the power head? What oher product would you recommend to clean the water passages without disassembly of the power head? Thanks for any and all opinions and suggestions.
