Suzuki 2 Strokes

I got a second hand CCI oil pump for my triple because I had an unfixable leak. I got a new gasket to check the condition of this ones springs and internal what nots. Problem is I took it apart and had to swap the arm and now I don't know which way the throttle accuated shaft sits at idle vs wot. I checked out the pink possum page and there is one picture of the pump head with shaft and arm still installed I just don't know if I should take one picture as gospel and possibly run the engine with far too little oil. Any definitive known advise on which way the eccentric sits at idle vs wot???

In the words of Reagan, trust but verify.

That pic is correct but the easy way to test it is to run the bike and let it get warm and them manually crank that lever to full open and wait a moment or two. If it starts to smoke more and more at idle, it is correct. If it smokes less manually pulled to wide open (the pump not the throttle) then it's 180 degrees out.

Ok I'm reviving a wreck so I have never seen it run well. I am not familiar with how much smoke is normal vs what's just built up in the exhaust and that whole mess.

An even easier way to check shaft orientation is assemble pump, connect it to an oil supply, bleed it, then turn the gearbox driven shaft with a piece of rod through the pin hole (doesn't need to be faster than by hand, say 1 turn per second using your finger on the rod). Observe the 6 holes in the pump base. When the oil pump lever is left alone, you should see modest amounts of oil emitting from all 6 holes, more from 3 of them than the other 3. Push the lever to WOT and keep turning the pump. If you've got the top shaft in correctly, its will SPURT oil from 3 of the 6 holes. These are for the upper cylinders and go waay high vs idle. If its t'other way around, you'll have lots of oil with the pump lever at idle and this will reduce at WOT.
I found my GT550A pump top shaft 180 degrees out when I first started the bike. Drank oil like a sailor!

An even easier way to check shaft orientation

Makes me wonder how they did it at the factory??? There must be an easier way, but I don't know what it is. I have a pump with no arm and I know the lever shaft has been rotated, because I did it myself. I think I left the arm on the pump actuating shaft (750) I sold to TZ. If I had the lever, I wouldn't know if I was right or out 180.

Hi,during assembly at the factory the pumps would have been supplied ready for fitment..dabs of paint to align things no doubt,so you couldn't get it wrong
Cheers,

If you have the shaft 180 degrees off you'll know it by the mosquito killing smoke. I found that out the hard way!

With the 750 pump ... as the arm swings to full on , the shaft in the bottom moves up .

Don't they all? Might have something to do with where you're at in rotation. I was checking mine (550) by chucking on the shaft in my drill press and holding the pump body with my hand. I remember the body going up and down as it spun. Yes / no?

I have my old pump apart and one way the arm position makes no difference on shaft travel. Then when it's 180 out from that the shaft has much more of an up and down variation with the arm travel. Problem is it sticks in a spot and the spring snaps the arm back later in the rotation then. Don't know if that's normal

yep .. that can be normal
