I just pick up an 2005 FLHTCI. I changed all the fluids. Not knowing what the previous owner had used, I put synthetic in all three holes. Now the problem is the primary is leaking a little on the bottom. I've heard this can happen from time to time, because of the synthetic. My question is has anyone had this problem, and then switched back to a petrollium base oil and had the leaking stop or is it going to leak untill a new gasket is installed.
Thanks In advance Jonnierock
