external oil lines to head

[Guest]

Hi all,
I have a GS1000 (2v) the head has been converted to under bucket shim running Anderson S3 cams H/D valve springs etc.
The head has also had the side plugs drilled and taped with oil lines put in externally from the rear oil take off to give more oil to the top end.
My Q. is, I've been tolled that the oil way in the crankcase top half should be blocked off to give better oil prissier to the cams, will this be right?





Not the best pic but you can see the extra lines.

Wow! That's a lot of work (and $) on such an old bike. My kind of guy, and my kind of bike.

(Sorry I can't help you with the technical info.)

I'm not an expert on 2V engines but typically oil to external lines is taken from the main gallery. This mean that there is the same pressure at the starting point of the external lines and original oil ways. So blocking the oil ways won't make any change to pressure on the head. As far as I know the main reason for blocking the oil ways is to eliminate potential leak points on head gasket and base gasket. If you aren't worried about leaks I would leave the original ways open.

Can we hear more about your bike and the mods done to it? I haven't seen anything like it over here.

Can you post pictures of the splitter and how you installed it at the oil port? Also, how are the pilot lines to the head plumbed into the cooler lines or are they? Did you install the higher
pressure 750 pump gears?

He is running a 1000 2 valve engine, the 750 pump gears won't fit.

I'll wait for others to answer that statement Gustavh. Meanwhile, I will be patiently waiting to hear from the OP for answers to my, still valid, questions.

the gs750 pump gears will fit... its common mod to improve oiling on the 1000

yes they do......

[gustovh]

I stand chastised. So 16 valve oil pump fits a 1000, nice to know.

No the pumps do not interchange, just the gears.

refer to my previous reply GS750 8 valve oil pump GEARS can be used to increase oil volume and pressure on a GS1000 8 valve

no where has anyone said anything about 16 valve oil pump fitting, we are talking about the gears that drive the pump

ok are we clear

I also would like to know more about this bike… OP, please post more info and pics!

[Wraith]

Well where to start some pics, some older than others.








As to the Q, and specs of the bike, I've not got any pics of how I've done the external oil ways (can't find them ) but what I did was to drill and tap an oil pressure switch (aluminium type not plastic!) to attach to a standard size brake banjo bolt and connected it in where the oil pressure switch goes at the rear of the motor on the oil cooler take-off block. I connected a line from that switch to a front brake line splitter and then connected the resulting 4 lines to the head at the blanked-off external oilways either side of the head inlet and exhaust areas, the blanked-off oilways being drilled and tapped to take the same size banjo bolts.
Hope that makes sense

As to the rest of the bike, the engine is a GS1000G (2 valve) bored to 1148cc using Kawasaki GPZ1100 1170 pistons. Welded/balanced crank, Andersen hi-lift race cams, CV ported head, under-bucket shim conversion using MTC buckets, APE heavy duty valve springs and HD engine and cylinder studs, HD clutch and back plate/springs etc, slotted cam srpockets, GSX750ET 4 valve oil pump gears. Running Keihn CR 35mm roundslide carbs & 13 row oil cooler.

It has Honda NTV 600 single-sider s/arm & rear wheel (modded to fit frame and shaft). Front end is 600 Bandit with progressive springs and GSXR 1000 k2 callipers. Homemade seat. Tank is modded GS 650 Katana, fairing is from a Peugeot scooter old model, rear cowling also off some scooter. Frame fully braced (Headstock, s/arm and cradle).

Probably forgotten loads: been working on it in various guises since before 2000 so it's ad a few changes (and will have more)...

Very, very creative! I like it.
