I have a 2007 Vulcan 500 with 19k miles. It was leaking coolant and was told it needed a new mechanical seal. Replaced it with 2 new gaskets, all OEM, put it all back together with a torque wrench. Went to drive it and while it was sitting, before turning off the ignition I noticed it leaking again from the same place. Any suggestions are greatly welcomed! Thanks a bunch!
