The rubber O-ring is missing. The OEM part is $2.98 at bikebandit. You’ll see it in the oil pump schematic on their site or other OEM suppliers. I’m not sure about fitment of other rings or seals. I usually swap these out every couple oil changes.

If you buy a Fram aftermarket filter (CH6015), it includes a replacement o-ring. My local Walmart stocks them. Might be quicker than ordering a replacement from the dealer, even if you just throw the filter away.

thnx for the info guys , might be a litle too far away for me to shop from a wallmart given the fact that I live in Athens Greece.
But thnx anyway.
Will this do anything to stop the leak until I buy a proper O-ring? (look for Viton O-ring for better?)

I would spring for the o-ring. If any of the RTV gets into the oiling system, potentially bad things could happen.

Rtv???

RTV = the gasket sealant above. I agree it's a bad idea.

I'm sure you can find an o-ring that will fit properly. Take the piece with you to the store.

Room Temperature Vulcanizing, usually it is RTV Silicone Rubber, it is great stuff for sealing odd shapes but if some oozes into the cavity and then breaks loose it can clog oil passages and kill your engine in short order. If there is no bike shop handy or automotive supply with an apprpriate O-ring look for a tractor/heavy equipment shop. I would take one that is too large, cut it down and glue it with super glue (usually works quite well) before chancing getting a glob of RTV in the oil pump.
The stuff in your picture appears to be a sealant to be used with a gasket which might be even less appropriate than trying the mentioned RTV which is usually used in place of a gasket.

If you tune weaker and get less efficiency, then to achieve the same power you must use more fuel. Less efficient inherently means higher fuel consumption.

Someone on the Super Sherpa yahoo group put the flat-slide carb from an XR250R in a Sherpa. Join the group and take a look in the message archive, and you'll find the info.

That was me, and it worked pretty well, all things considered. It's a round slide carb, not a flat slide, and it's a tight fit, but it will go in. I ended up using the throttle assembly and cables from an XR250 as well. The engine-side spigot of the XR carb is slightly smaller in diameter than the stock carb, so I cut a ring of rubber off of an old airbox carb intake boot in my junk parts pile. It fit tightly over the output spigot of the XR carb, and the combination fit nicely into the intake boot on the engine.

With the stock XR250 jetting and needle, the throttle response was much quicker, more crisp, more like a dirt bike. Low end and midrange seemed stronger. Top end petered out earlier than the stock carb. You'd expect all that, as the bore diameter of the XR carb is smaller than the stock carb, so you'd get higher intake velocity.

I never did get it fully sorted out, but it definitely works. I rode it that way for a while in the south jersey pine barrens, and it was an improvement, as you could throttle up in the sand and keep on top of it better. I think there's additional performance to be had with the snorkel removed and a low restriction exhaust. But then I'm not sure it would be a Sherpa - it would be something else. Better maybe, but something else.

BS, efficiency can be changed without changing the jetting for fuel consumption.

Does DrJeckle mod tune the Sherpa for weaker power output and less fuel efficiency? I think not.

Details man! What are the parts off of?

I'm not clear what you are trying to say or what you are calling "BS"?

Are you claiming I am wrong?

[Cat0020]

By changing out the Sherpa OEM jets for bigger jets, fuel consumption is going to be increased, regardless of efficiency.

Efficiency has to do with relation of the distance traveled, fuel consumption is just how much fuel gets to flow through the carb., could be zero distance if you're just sitting there idling... but still fuel consumption is greater with larger jets.

Pantheman was asking about consumption, not efficiency.
