When I replaced my cooling system hoses,o-rings and water pump seal two years ago on my '99 VXII,I was concerned about how easy the water pump input tube slid into the pump

.It was as if the o-ring was too thin,even though it was OEM ,it had very little interference.I thought o-well the original lasted 15 years,it should be good to go,

I should have known better.Two weeks ago,I saw a drop of coolant on the floor under the left header tube,and on the bottom of the tube,but could not find the source.Thursday I started the bike, ran it until it was warm and shut it off.Last evening I saw it seeping out it the water pump inlet.I removed the o-ring,and it still measures the correct cross section[3.2mm or .125].I went to our 0-ring assortment in our shop,found an o-ring with a .139 cross section and installed that today.It installed with the resistance I am used to.

I should have done it right the first time.
