On my Shovel someone prior to me actually drilled and tapped an extra oil feed next to the factory one that feeds the top end on the case. It did have a couple copper lines, one going to the front head, one to the rear. Last time I did the top end I took them off, plugged the extra hole and just installed some stainless braided lines, one to the rear head and the crossover to the front. After that it seemed like I had a little more noise from the front rockers so last night I bent up a line from the extra feed hole on the case and routed it to the front cylinder but also left the crossover. So I have one line to the rear head, one to the front head and the crossover line still on there. Anyone see any issues with this? Guy at work I was talking to said he'd be worried about possibly sending too much oil up there, I say fooey. What do you think?

 

I've heard of using larger lines w/ no problem. How's it working out?

 

Top ends are over oiled from the factory , there's a fix I use on them to get it down to livable been around forever . The port coming out of the case and that fitting ? The actual size hole that should be in there is only .060" , you'd be amazed at how many gasket & o-ring problems along with oil pushing past the valve guides suddenly goes away . I solder a plug in the bottom fitting and drill it simple as that , do a little net digging I'm sure it's in print still floating around .

You hearing a bit more noise up front just means it wasn't flooded as usual , worse case rocker arm bushing are a bit loose . It's a shovel they may be .
