    So just got back from the garage, looks like the 2 stroke pump has had it. He started it up and he felt it sounded ok so he'll start with the pump before taking the head off.

    The only issue is that he quoted £400-500 to rebuild the top end, is that not a bit extreme for a maintenance item? We're not talking a panigale here, or am i being soft? Its approx £100 in part according to yambits so 8-10 hours labour?

      @me0u01c1 That's a lot of money. The pumps are pretty reliable and don't tend to fail

      If the pump has failed, then you've failed to lubricate the small end bearing (fine that's included in a top end rebuild), the big end bearing and the mains bearings.

      All of these must be inspected prior to rebuild, else your fresh top end will not last.

      If this were me, I'd be inclined to fix it myself. It's really not that difficult.

      If you don't want to do it, then you have to pay the price for someone else to do it.

      In my Opinion, £500 sounds like the price of a full engine rebuild. Usually see a full rebuild at around £200 mark, but if they're removing the engine from the frame they will charge that back out.

      The top end can be installed with the engine in the frame, and there really isn't much to go wrong.

      I wouldn't pay £500 for a top end rebuild, for £100 you could do it yourself. £150 with forged components.

      The rebore/hone will set you back £40. Pistons vary from £40-100 and the gaskets are £15.

      If he's putting a brand new pump on there then the pump is £80

      The price is the price I'm afraid.

        @Calum cheers for the info, tbh his first gambit was 'its a winter job' and then tried to sell me another bike so...

        Once I got it out of the van, and he had a play said he'd look at the pump (he pulled the 2 stroke feed off the engine started and nothing came out), and to call back on monday. If he can't or hasn't done owt with it I'll pick it up and have a stab.

        It was more the rush (9 days to MOD2) but for £500 and a couple of weeks wait I might as well have a go. I've done cylinder heads on VAGs in my yoof, just old and busy (ehm lazy) at the moment.

          Agree pump failure unlikely but can be repaired to as new for around £50 quid. Sounds expensive to me, if it is a full rebuild could save money getting engine out yourself if you'rehandy with tools. Ask supplier for contribution to repair, should have been in a serviceable condition at sale.

            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.

                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.

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

                      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:

                          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

                            @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

                                @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.

                                    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.
