Stop running this scoot for the moment. Your oil pump is missing. It should be to the right of the stator, immediately below the ignition sensor. (Thanks to McCrew for this pic) Only continue to even run the engine unless you are properly pre-mixing or you replace your pump. Many here would recommend that you do the former, but there is increased inconvenience associated with that. My scooter is a genuine Yamaha and my pump is completely dry, not a drop of oil anywhere near it. I think a good optioon is to get a genuine Yamaha oil pump to be on the safe side. Assuming, of course that it will fit. Maybe Brent, Reveen, or 2Strokd can chime in on that.

The pump is there. Its not a cable operated one thats all. If your concerned about it working proper. This is how i do a sure fire test... Take the airbox off, or move the inlet hose away from the carb. Next start the scooter and with your how ever you can get some 2T oil in the carb while its running. Next. pull the oil line off the carb and rev the scoot some. You should see oil slowly pumping out of the line. If not, its not working....

Hang on a sec, 2strokd. Bklynfinest911 said that there is a cable. He has already traced one cable to the carburettor and the other one isn't going to anywhere. While I agree that your test is a way of checking (I've actually done the same thing recently, but by removing the sparkplug and using the kickstart instead of risking further damage by running it), I am concerned that the pump was removed. I increased the size of the original pic and posted it here. I put a ring around where the pump would normally be, for the benefit of the OP. As you can see, the pump is missing from that location. Where else would it be located (so that it doesn't need a pump cable) and what would that other cable be for? Oh...to bklynfinest911, use tinypic.com as a host. Imageshack is crap.

Looks like the pump and the cable have been pulled to me (if there is one?) The oil hose is missing too. Isn't it? PREMIX!

That is the oil pump... You just havent seen that style yet. Here ya go... www.sip-scootershop.com/EN/Products/Oil+Pump+_R100110050Honesty IMO, i think that style is better. They only use what the engine needs via vacume instead of "force feeding" oil in all the time. Im guessing his scooter is supposed to have the cable operated one and his engine has the vac. operated one?...

Tango,You dont risk damage if you put oil in the carb manually when its running. Easiest way to prime a pump IMO. Put some oil in the carb, fire up the scoot, crack the bleeder on the pump until oil comes out. Close the bleeder on the pump... Shorty after oil should start flowing out of the lil line. I use a small oil can with a manual pump to squirt oil in the carb so it never starves one bit

Im guessing his scooter is supposed to have the cable operated one and his engine has the vac. operated one?... Now...can anybody explain to me why I shouldn't love this messageboard?!? Shoot...I'm learning stuff EVERYDAY! Very interesting. I actually prefer the cable method. Think about it...if we're held to such ransom by the failures (or risk of failures) of the petcocks I don't think I would want to run the risk of the diaphragm in the oil pump failing in similar fashion! Your theory regarding the cable seems relatively sound because I've really heard horror stories (??) about scooters being put together in those Chinese factories with parts that are available today, and a different set that are available tomorrow! They design the handlebars for cable pump and then tomorrow engijne with vacuum pumps arrive. Oh well...assemble them and get them through the door!

My manifold is all crakced and I don't even want to touch the carb right now, lest I open a hole or two in the manifold. I'm getting set to replace the carb and manifold in a little while, and am thinking about getting a performance setup. We'll see.

well - isn't the oil hose that takes the oil to the carb missing then?

At best, I would think that if this is indeed a vacuum oil pump then it is not identical to the one 2strokd posted (perhaps the oil line and vacuum line run in a different direction??). That much is clear. But I would still suggest that the OP just sit tight until he can ensure that everything is where it should be.

The feed line going to the carb is on the other side. Its simple really. Hook the big one to the oil tank, bleed the system, then when oil is pumping (again engine must be running to do so) plug the small one to the carb. Just make sure you put some oil in the carb while its running so you know it wont starve any

Its the same other than the inlet nipple has a 90 on his and the one pictured at SIP has a straight one.
