Yet Another Newb Oil Question
I have either a 96 or 99 Evo, just picked it up a few weeks ago and got around to change the fluids tonight.
The problem is now once its started it is leaking majorly around the oil-lines, I pulled out some some oil and left for a bit and came back started it again and this time it seems worse. I came to the conclusion either it is still to full or the oil filter (which id some off brand the local shop sold me). I was going to start tomorrow by picking up a K&N 170.
Has anyone seen this happen before, the lines almost blowing off. The oil tank does not have a dip stick, instead its a decorative brass plug. Ive read all the post about overfilled oil tanks but no one seems to have had this issue. The initial drip i thought was perhaps just a loose hose so i tightened it up, the second one it was coming out fast.
I'm using Mobil 1 V-Twin.
Thanks in advance for any help

You are using synthetic oil, this is often the cause of leaks.....your oil lines could be just rotten and porous...DON'T BE CHEAPASS WITH OIL FILTERS!!!!!! Sorry for yelling but people just don't get it....buy a good aftermarket or use a genuine one....then you know it is right.

It can and does happen....switch to mineral oil and report back but you may possible have a blocked breather or a cheapo oil filter....do oil and filter swap and report back with the results, once we know what effect they have we can sort it out for you.

Sounds like the return line and the crankcase breather line are swapped at the oil tank, thus the PO installed a brass cap instead of the rubber stopper dip stick that kept popping out.
So, do change the filter, change the oil to HD 20w-50 or equivalent. Then check which oil lines are attached where on the oil tank, atmosphere breather, oil filter(if separate from engine) and oil pump.
The routing of the oil lines MUST be correct otherwise you get your situation.
Also: Get the serial(VIN) off the engine and go up HD web site to find out exactly what you own. There is a VIN check section. Will identity year, make, and model.

I only said 96-99 cause on of the shops I called said they thought it was POSSIBLY off a 96 ultra classic. The vin on the is FLRT601687.
I have no reason not to believe the church that sold the bike.
If the oil hose routing was wrong would it not have been a problem already?
I will pick up a different filter and pull some more of the oil out of the tank first. I was just thinking if the tank was over filled that may cause increased line pressure but wasn't for certain.
