My girlfriend's 2004 sportster custom has an oil cooler. I changed the oil a few weeks ago and it has had a small oil leak by the oil filter/oil cooler area. I don't think the oil filter is leaking (no oil on underside of filter) but I did notice that the oil lines that are running from the oil cooler had oil on them. Is it okay to slightly tighten hose clamps? Not enough to alter the flow ofoil, just enough to tighten the clamps and hopefullyseal anyhoses that are lose and leaking oil.

I have washed the bike a couple of times to make sure all oil residue was gone so I definitely know it is leaking (not from the oil change).

Thanks

 

just tighten the clamp. the hose has become more pliable and compressed.
