GS674R top end cam oiler?

[Guest]

Im curious to know if it would be beneficial to install a top end oiler on a 550/674 hybrid motor?

Curious to see the answer to this. Although I've yet to see a smaller CC biek running one.

Didn't those engines already have built in oilers under the valve cover?? I've had one apart before though it's been a good while and swear they had oiled tubes running to the journals...

Well, I can't give your a definitive answer, but

The pictures are a 16 valve motor , which is a completely different design than your 8 valve motor. I don't think I've seen an 8 valve motor of any size with top end oiling and that includes dragbike and roadracing motors.

So, in conclusion, I think top valve oiling is a 16 valve issue, not 8 valve

ALL of the Pro Stock Suzukis have oilers on the 8 valve Ward & V&H heads. Ray.

I bow before the knowledge of Ray. I don't hang out at the drags.

But, Ray, is my basic premise correct on the 8V/16V issue?

For the most part, yes, Big T. Ray.

So what would need to be done to plumb a top end oiler into a stock 8v head? The end plugs drilled out and tapped? Or would that not work?

It's basically a bored out first generation 550. I never heard of an early 550 having top end oiling or any other engine problems. The GS that put the bullet in bulletproof. I think when I do mine I won't mess with it.

Neither have I, but I'm simply curious. Someday I'd like do a big 750 or 1000 based build, and while it may be overkill or not absolutely necessary, if anything it can't hurt and it certainly, at least to me, looks cool.

Im working on the design right now, I think I will probably route braided lines up from the transverse oil gallery that runs along the base of the cylinders. dose anyone know where I can get an adapter to use in place of the drain bolt which is located above the points cover?
