Overhead oiler for 1982 suzuki gs 1100 gl

[mike J]

Dink, now we are getting somewhere. Makes sense that the bigger studs would restrict oil flow. A couple of questions, why do they sometime change to after market oil pump gears, I'm assuming it's to help the cam situation. Also if you add the outside oil passages do you plug the ones coming up by the studs? Mike

You can plug them up if you want to. I think it better to leave them open. That way the oil goes back down the studs to the crank. The 750 gears pump more oil than the stock 1100 gear.

Ryan, so by not plugging the holes you don't lose oil pressure? Im assume you have one of these on your bike? Can you tell me what other mods your motor has? Sorry for the 20 questions I just want to be a quick learner. Mike

Just another point of view. My bike with HD studs, and the 750 oil pump works fine with no cam oil starvation. The external oilers for most engines are not needed. Take a look at my web page (Click the link in my sig) to see what's been done. One benefit for doing the external oiler is also the ability to plug the oil feeds by the studs. It will allow you to go to higher horse power before needing to o-ring your block. Really only an issue if you're pushing big hp.

Well I've had a few 8 valve GS bikes, they are all pretty much "bullet-proof" but excessive top end wear as a result of overheating due to oil starvation is common, so for anyone concerned with engine longeivity, I'd say that a top end oiling kit is a pretty good investment.

Because of their popularity with the speedway set and the fact that they don't have the cult following here that the Honda CB750's and Kawasaki Z900's enjoy, many have gone to meet their makers so I haven't seen that many modified GS bikes, but a friend of mine has a nice 1980 GS1000S like mine, but he's running a big bore kit and street cams etc, and he has a top end oiler kit, of sorts.

I haven't seen him or his bike for awhile now since I moved, but he ran a cooler, and tapped into his adapter were two additional smaller diameter lines which split into two and terminated either side of the cylinder head near either end of the inlet and exhaust cam.

Not as flash as the anodised alloy blocks in the pic above, but rather a clever concoction of Earls braided line fittings and short pieces of line, I rather liked the look, more "racer" than "show pony". I might make one for my GS750/1000 project. Cheers, Terry. :twisted:

like this one?

Yeah Katman, just like that, excellent! :twisted:
