Oil pump failure? Not unheard of but uncommon for sure. That certainly explains things, I didn't even think about it. Well if it's just that I can't imagine much has gone wrong, these engines are pretty much bullet proof. I'd probably take off the head and see how things look, you might be lucky and just need to replace the pump which is an easy job.

@me0u01c1 Pretty sure the pump utilises engine vacuum to draw the oil through as well. They also use very little oil anyhow, turning the engine on and disconnecting the oil feed may provide unrealistic diagnosis. I'm not convinced at that I'm afraid. But I work in IT, what do I know.

[finnerz89]

I know from when I first fitted my clear oil lines that at idle the engine uses a minuscule amount. Even with the oil pump pulley fully rotated (maximum output) I reckon it took a good minute or two to fill the lines up to the engine. Which is what, 3 inches of 4mm hose?

@finnerz89 I don't think pulling the oil line off the engine is representative of "The oil Pump has failed"

Sorry but I want more reasoning than that.

[finnerz89]

@Calum I completely agree. He didn't even check the spark plug? Could be running really lean, has he checked the cooling system?

[me0u01c1]

Dunno tbh guys, he said he'd have a look and let me know, I'm just going to have to trust he knows his onions and not looking to be ripping me off.

The other garage in town wouldn't even consider looking at it for a month so not much option. I'll speak to them on Monday and see what the gen is, if its not 'fixed' i'll bring it home and get the spanners out.

And if that happens I hope you like pictures of engines and questions.... :smiling_face_with_open_mouth_smiling_eyes:

@me0u01c1 To be honest, we're all here any how and are happuy to lend a helping hand. There may be a member on here nearby willing to give you a happy end.

May sound stupid, but are you sure the 2T oil tank is filled, I've heard of people getting confused and filling the expansion bottle for the coolant with oil!
Never heard of one of these pumps failing

[me0u01c1]

@Glynn123 yep to the brim, it was his first call for 'pilot error' and it looked like it hadn't dropped at all (but then it has covered very little distance). I will admit I had a little panic when he mentioned it

Ha ha ha I hope you mean helping hand 'cos you normally have to pay extra for a happy ending.

[Glynn123]

@me0u01c1 that's weird yeah, maybe worth trying premix and keeping any eye on the temperature of the engine? Ofcourse run the premix rich and check for any lean mixture or air leaks first mind. Just thinking of quick fixes to get you on the road for now, the damage has been done, aslong as its got compression it should still ride until you want to rebuild.

@me0u01c1 no way I’d pay that for a half hour job the first rebuild I did was on my dt almost exactly one year ago I’d be happy to walk you through step by step

[me0u01c1]

So got it back finally, it was the oil pump. The old 2 stroke had congealed blocking intake so the engine and the pump have been running dry. The engine is running on premix at the mo while I get ready for my mod 2 on Wednesday and then I'll be looking at rebuilding the pump and top end. Thanks for all the pointers guys.

@me0u01c1 How frustrating.
