Scavenge pumps

[R1guy]

I'm sure I'm opening myself up to a load of abuse here, but I really can't work this out...

Ive currently got an electric scavenge pump, but fancy one of the mechanical ones that is driven off of the timing nut:

 

 

but how does the plumbing work for it?

 

my electric one is inline, so it suck oil out of the bottom of turbo and back into cases. But how would this work?

Line from turbo just connects to Black union on outside off case, and oil leaves pump from slot above screw (right side 1 in pic2) on the inside back into engine.

Same principal as an Emtes pump but your picture shows case with pump incorporated.

But the ignition points are behind this cover? They can't run in oil?!?!

I've had a windowed ignition cover on an oil cooled motor in the past. Through the lexan glass I could see a pulse of oil being sprayed in there so don't think oil would be a problem as the rotor would be moving fast enough to flick off any excess oil that may affect the signal.

You've never looked inside a GSXR engine have you! They do and were designed to run with oil - in. over and around them.....Oil is an insulator

and has no electrical effects on magnetic pick-ups...........NOT POINTS!

behind the ground plate of the ignition pick-up you can even see the crankshaft through a hole in the case. It's supposed to be oily there.

where can we get these pumps?, and how much?

[Gixer1460]

Used the Emtes version and got it from NLR in the States a good few years ago now. I think Stu at Warpspeed can do you one?

That’s the type of pump I’m running 

got it off a someone who got one but never built a turbo bike 

works well and better than a electric one as know it’s working all the time 

[Askamaskinservice]

Would this be usable.

It will fit if you make a housing for it.

An internet search produced a solution in the attached picture.

I made my mechanical scavenge pump using the oil pump gears from a H O N D A CT90. Works perfectly in place of the water pump on the WC engine,
