Overhead oiler for 1982 suzuki gs 1100 gl

[Anonymous]

Hey does anyone have some pictures of an overhead oiler for this particular bike. I live in florida so I have to make sure every compnent in my engine is well oiled and cooled. Any other suggestions would also be appreciated.

Like this?

I've not sure if I've seen one for the 8 valve engine. They do make it for the 16 valve motor like what Rosco15 showed you.

I've got an 81 750 L. Would that oiler shown work with my TSCC engine?

No. The oil pickup that is located behind the cylinders on the 1100 TSCC engine is not found on the 750 TSCC engine. You need that pickup.

Can't you connect to the plug between the clutch and Magneto cover? There's another one on the stator side (part of the cover) that you need to drill out from the inside of the cover.

That is a possibility. If you did elect to do it that way I would just put a "T" there and run a line across the back of the engine to the other side. I question if it is really needed on the 750 for three reasons. First, the main reason you use it on the 1100 is because if you have heavy duty cylinder studs, the greater diameter of the studs can restrict flow to the head. Second, the 750 has a much higher oil pressure due to its' plain bearing design and it probably gets plenty of oil up top any way. Third, because it is a high pressure oil system, routing the oil via external oil lines might drop the oil pressure in areas of the motor that you want to keep a high pressure supply to (like the main crank bearings).

Hap, I thought the 450 or something was the only one with the standard bearings???

For some reason (costs, I'm sure) Suzuki elected to have plain bearings on the 16 valve GS750. That is why a lot of people use the 750 oil pump gears to increase the oil pump speed on their 1100. The 750 has a one piece forged crank (a lot cheaper than the 1100 crank) and the plain (or shell) bearings on the 750 are a lot cheaper and easier to assemble.

The earlier 8 valve 750 did have a roller crank.

Did you sell the 1100?

All excellent points Hap. On my 1100 I just installed the 750 gears. I love the way the external oiler looks, but I just can't justify it at this time without the oversized studs.

Sell shmell
I have a set of megacycle cams and a new timeing chain waiting to go in. Just a second ago i was telling a friend that i want to trailer the bike to Beaumont to ride with the Texas bunch this fall.
SELL??????????

The two valve motor should not need the oil cooler lines. For a start, the 2 valve uses shims which are always in oil. The 4 valve uses rockers. With oversize studs and rockers elevated above the oil in the head, some problems may occur.

With the 2 valve, an oil cooler is all you will need. The 750 gears will push around more oil.

Can someone go into detail about the oil mods here? Forgive my ignorance but I just want to learn more about the why's and how's . Mike

Relatively simple, in the 16 valve 1100 motors many consider the oiling system to be upside down; due to the fact that the crankshaft is roller bearing and the cams are direct into the head. Roller bearings can live with marginal lubrication quite well, but the camshafts cant because the first thing they damage is the alloy of the cylinder head.
So for his reason the topend oiler kits were developed, they take oil direct from the oil pump directly to the cylinder head, to give a better and more consistent supply, the other reason for doing it is drag racing applications were massive big bore kits and oversive studs etc are the order of the day , it was found very quickly that oversize studs restricted oil supply to the cams; and in fact is probably more likely the reason for development than anything else.
