If you value your cams!

Well, I have been working on my bike changing things back to the way they are supposed to be. One of those things was taking off the oil cooler that the PO had mickey moused on. If you value your cams at all I would suggest that you do not install an oil cooler between the top and bottom end oil line on the back of the engine. The PO had cut the hard line that runs from the case to the head and had spliced in an oil cooler. So while removing it I decided to pop the valve cover and have a look at the cams. With only a little over 5k miles on the bike there is already some scoring on the cams. I believe that this oil cooler had decreased my oil pressure, and was starving my cams. Anyways, I just wanted to let anyone know, incase you were thinking about doing this to your bike. I think I caught it soon enough, but I'll know before too long I guess.

The oil cooler is supposed to be connected to an adapter behind the oil filter. Tapping into the top end oil feed line is just pain stupid.

The only good news is that used stock cams are cheap.

it probably wasnt from lower pressure but from lack of oil- the oil from the cooler would probably drain back down and when you start the engine, it would have to fill the cooler back up before lubbing the top end- no oil on the top for a lot longer than normal.....

Low pressure

I was reading those posts months back and thought it was a loopy way o' doin' things, but not having the experience of hooking one up, kept quiet.
Would seem that tapping into a pressure system and adding a cooler that just freeflows in and then drains down would rob the pressure from the cam bearings, but I hadn't really thought too hard on it. Would seem easier to flow through a cooler than to squeeze past the cams and bearing surfaces, and that's the route the oil would take
