    The pumps are not refurbushable. A new pump will be required if this is the case.

    The oil line feeds directly into the inlet manifold not the carbuettor.

    The carburettor will accept coolant lines, so get those the wrong way round and....

    It's not uncommon for the pumps to fail, in which case the best advice I would give would be to simply run premix.

    @calum
    Thanks again!
    Seems strange a fragile part like this is unserviceable but l have managed to source a couple of units so l will check which works the best and replace the old one.
    Now this should really be one of the last fixes, l can wait to finish off and enjoy the fruits of my labour!
    And post a picture for you guys of course! 😂👍

      The coolant feeds will be there to warm the carb to help prevent 'carb icing'.

          @oldman Yamaha told me they were non-serviceable. Interesting.

                  Wow, the oil pump looks fantastic.
                  I would love to have the guys details, pre mixing seems quite prehistoric.
                  And l would love the engine working all correctly......darn these OCD’s! 😏

                      @spanners Nah man, OCD is good. Forums are OCD.

                      IMO, get it running spot on. It's worth it. But a lot of people tend to be short on cash, so I was merely offering a quick win.

                        @spanners We all have OCD in some way, shape or form bud. And there's absolutely nothing wrong with having a healthy obsession on/in something, it just proves that you have a soul and take great pride in creating something beautiful!!! 😉

                          IMHO if it's there it should work, annoys me if it doesn't, keep thinking about it until I give in and correct it.

                            Well guys I’m certainly in the right place with this forum.
                            @Calum I realise and understand your thinking, you always offer a way to still ride the bike to enjoy it. 😃
                            I just want to get shot of the bodges, turned screw heads, snapped bolts and quick fixes.
                            @oldman thank you for the contact, I really appreciate it. I’m hoping both the pumps l got hold of work, then l can send one off to be refurbished.
                            @NINJA thank you for your kind words, l say great minds think alike...... and congregate in similar places!
                            I should be able to take it out this weekend, even my new rear fender for AJ Sutton has turned up, that has got to be good luck! 🤣👍
