The reason I suggest filling with distilled water is then it would prep for the next option to use diesel engine block sealer (or other silica based sealant), the coolant system needs to be clear of the antifreeze... add the sealant, and follow the instructions, heat cycle the engine, drain the water/sealant mix and let stand for 24 hrs. Not optimal, but if you are in a "need to do this, no other way out", I would not be afraid to do it and leave it that way.... provided it fixes the issue but I would only do this after a retorque and maybe as a safe guard to a failed/failing and healed up from retorque head gasket.
Thanks so much for the tip. Any long term negative effects of using a sealant like that in my bike? I'll definitely try that route if torquing the heads again doesn't work. I think I have all the tools I need along todo it, if not I'll buy them!
