radiator stop-leak ?
my manual says to at 2.5 oz of radiator no leak to the coolant system when filling. is this really something you should do?

Re: radiator stop-leak ?
Would it be in the manual if it wasn't necessary?
I was born with nothing and still have most of it left.

Re: radiator stop-leak ?
I can understand the recommendation back in 1972 when there were not many water cooled bikes around, but it should not be necessary. I didn't use it on any of the GT750s I rebuilt but if you get an annoying weep, you could use it.
