I very much enjoyed reading this post, what a nice bike.
Your skills are obvious and to be envied.Comment

you do not need that much oil in the top end of a bucket engine-- and what you mentioned is called DRY BLOCKING -- when you block the oil flow from going up the rear outer head studs.
and BTW your outer oil lines are way overkill but they do not force oil where it is needed - inside the cam caps/ cam journal.
once dry block modified you need to improve oil drain down with extra holes every where top to bottom. I believe it is more effective if you have rocker arms to lube the buckets are more resilient.
My opinion - and it is based upon dyno results of my 1238cc 8v engine with and without the hi volume pump gears, hi volume ratio will make your racing engine slower. they help a street engine at idle but not at WOT -- hate to break it to you , you'll get better results using thinner oil 5w30 or synthetic 0 weight and standard oiling equipment.
parasitic hydraulic drag - also had involvement in a stock appearing Bonneville buell/Harley - and the oil pump was 50% the size of a stock one (smaller)- made almost 20 MPH difference. 159MPH with Cammlin/ Weebler's team in 07.
I'll give you permission to go ahead and tell me how stupid I am. as I laugh.
I have another question -- what did you set your valve seat pressures at with the APE springs? - might be able to help with another mistake builders overlook.SUZUKI , There is no substituteComment

To your Q. I don't know as I gave it the the engine tuners and they set it up.
Got some more pics for you all.
May not give lods more oil up there or it may (I was told when I first did it years back it helps mostly with the exh cams) but it looks good

did you ever notice how many different oiling kits available on the performance market for kz900/1000 and how similar they are to the GS 750/1000?
lucky to have a good shop that handles your machine work and knows how to set up a hemi.
good looking resto mod. it would be a 1 of a kind around here.SUZUKI , There is no substituteComment

trip i am puzzled by this comment of yoursyou do not need that much oil in the top end of a bucket engine-- and what you mentioned is called DRY BLOCKING -- when you block the oil flow from going up the rear outer head studs.

"but they do not force oil where it is needed - inside the cam caps/ cam journal."
thats where the oil passage ends how can it not force oil there, please explainComment

IMO bucket type head are safe...near bullet proof unlike a rocker head.
i have seen kawi's...big HP kawi's feeding the top end but i assumed they had blocked the oiling from going up the cyl. studs and was just replacing the feed source and or had crazy seat pressures.Comment

nicely spotted Agemax, i assumed he had tapped into the cam oil gallery , thats what 99% of top end oilers doComment

the oil lines are really cool.
bullet proof exactly! blowerbike you hit it right on the head!
cams twist at 50% of crank rpm. yeah so what. the journals are designed to share the load - don't get that much don't need that much oil.
HOWEVER buckets tops DO wear into a dish not because of lack of oil but -- seat pressure/aggressive lift/ramp design - and you got have seat pressure to get a good compression seal at redline .
if you lighten the bucket and lighten the valve and lighten the retainer that is development that gives you a return of power and longevity.
my favorite parts are always inside the engine, you can't see them -- the oil cooler and extra feeds are not necessary to maintain a high performance engine on the street.
please, you have a cool bike- I like it.
dry blocking, filter bypass, and a huge vacuum pump hooked to crankcase vents gets a bath of oil up to the rocker arms then out of the all the moving metal's way (16Vgs/gsxr need it.)SUZUKI , There is no substituteComment
