Yes I am running the lines to the back of the valve cover. This is a drag bike so oil cooler has been deleted,I have the billet crossover block installed on the oil pan. If that helps.

Yes this is a 90 GSXR motor 1340cc 425 lift intake 380 lift exhaust had the block done at Carolina cycle who told me I needed a top end oiler and would have to remove oil galley jet and plug those holes which I did.upon initial start up had 90psi of oil pressure at the test port APE springs were set to 60lbs of seat pressure, ran the bike minimally in the shop made a couple of test hits and brought it back to the shop to inspect.i took the valve cover off and had knarled up 2intake cam lobes and 2 rockers which were new hard weld from web cam but the exhaust cam and rockers were fine?I'm running brad penn 20/50w oil .

I have installed a ward top end oiler on my drag bike have blocked off oil jet galley on the back of the cases but am having oiling issues any idea's would be appreciated
