    Right, I guess buying a new fuel pump would make more sense rather than cleaning this. Chances are that in future it can go kaput. The rubber gasket is accompanied with the new pump set ?

    Noted the over tightening point.

    I am still stuck with rusted fuel tank. Dont know how to remove the rust stuck to the walls and base of the tank. Any tips ?
    No. The O ring doesn't come with the fuel pump, that's a separate part as far as I reckon. Secondly, you can use normal nuts and bolts or a small timing chain inside the fuel tank and give it a good swash this will remove the rust deposition pretty much easily.

    Once upon a time, a guy asked a girl 'Will you marry me?'
    The girl said, 'NO!'


    And the guy lived happily ever after and rode motorcycles and watched sport on a big screen TV, went fishing and surfing, and played golf a lot, and drank beer and scotch and had tons of money in the bank and left the toilet seat up and farted whenever he wanted.

      Will try that with nuts & bolts. I also saw a guy on YouTube named 'Top End' cleaned his RC tank with sodium hydroxide & Hot water. Wondering if same can be done in plastic tank..

      By O ring you mean that flat rubber that have threads in them, right ? Just to avoid confusion attaching 2 pics. One from the spare part manual. Another from the pump that I have. It was installed at the internal base of the pump.Click image for larger version

        Yes, that flat rubber is what's called the fuel tank O ring. Yes, that's caustic soda, and he uses it on metal tank. Sodium hydroxide can be used in plastics, PVC won't have any trouble, as a matter of fact the tank itself is PVC, so it can be used easily for cleaning. He also cleans the fuel pump with the same solution, but I'd rather replace yours considering the amount of rust accumulated. Make sure you use PPE while using caustic soda.

          VJ I am no expert, but like you said cleaning a Plastic tank of old petrol and goop is easy. Petrol itself can be used , or Kerosene, or Coca Cola can be used to clean out the tank...Coca Cola had carbolic acid which cleans from Radiators to Toilets.. The Plastic used in Petrol tanks are mostly resistant to this . The presence of water seem to have caused extensive corrosion of Pump and other metal parts.Please check by cleaning the parts if it is corrosion or muddy gook in the Tank coating itself on the parts. .If it is corrosion then the safest method would be to replace the Pump along with filters, and the Injectors may also need cleaning ...
          Good Luck.

            [MENTION=24497]Veeral[/MENTION], I think psr sir, has laid out some more techniques and tips on how to remove gunk from a plastic fuel tank. Basically, plastic tank is far easier to clean than e metal.

                As pathetic as it is, it can create a hole in your stomach, if the consumption is such that. YT is full of DIY videos on cleaning from as psr sir rightly said, toilets, to floors to car rusted floors, to rust removal of old geezerhood articles of yore. And yet, all along, its concoction is still a secret. Should be mild phenyl and sweetners, hence the secret.

                  Thanks for the confirmation on O ring. I've seen few unboxing videos where the O ring is preinstalled at the base of the fuel pump. I did try the caustic soda, well it flushed out the rusty goop but still there is rust layer on the side walls which just doesn't come out even after trying twice with caustic soda. I also cleaned the fuel pump with it. It looks better than before but tried turning it on via battery connection but it just gives sound 'Click' a slight movement and then nothing. Wire starts heating up. I suspect a short inside the motor. I better replace it.

                  Thanks a lot for your valuable tips. I tried caustic soda but still there is rust layer left on the side walls which doesn't come off. I guess coca cola should do the trick. I've posted a comparison pic of the pump before and after cleaning.

                    You can try using coca cola as psr sir said, and give it a good brushing inside the tank, if you can, which would mean it clears even more goop. Secondly, yes, wire heating up means bust motor. Wire shouldn't heat up, meaning it's shorted somewhere and eventually the wire will burn.

                      I have 2016 model and recently did a bleed of both front Brake (already have EBC strinted pads) and rear brake, the brake feels like new.

                      Recently bought a used duke 390 2015 model run about genuine 25k km. It runs absolutely brilliant, but the stopping power is way less, not even compared to dominar. So to imrove breaking i am planning to do the following things. Please provide your views.

                      1. Sintered pads from 2017
                      2. New brake master cylinder from 2017 model
                      3. New disk on front, as the present one is having few grooves and markings.

                        Hi friends,

                        Posting after a long time. The bike was lying idle from past few months due to lockdown. I only started it sometimes in 7 days, at other times in 15 days. I was lucky enough that the battery didnot gave away. Right now, I ride the bike occassionally. I have a few questions, I have a 2019 model Duke :

                        1) Does adjusting the rear suspension affect ride height ? If so does compressing the spring reduce height or increase it . Am asking this as I want to reduce ride height by 2 inches.

                        2) Does anybody has any experience with aftermarket windshields performance? Do they affect handling at high speeds? Asking this as the windblast above 90 kmph is unbearable for me.

                        Thanks.

                          Thought so. Visited one of the service center nearby my office to get the fuel pump and other spares. Inventory seems to be an issue with them these days. Since they have just started operating, procuring the fuel pump will take him 20-25 days. Will try one more service center or else will have to wait for 20 days . I wish there was online shop for bike spares. There is this website 99rpm, but they only have fiat and bajaj spares.

                            No. Adjusting the rear suspension, compressing doesn't affect the ride height "much" but yes, you can feel a mild difference in the bike having a lower set feel. Aftermarket windshields do help a lot when it comes to windblast, and windblast is as pathetic on naked bikes.

                              Yes you can easily reduce the ride height by 2inch, however it'll also reduce the ground clearance so you should have it in mind while riding with a pillion over some unusual humps.
                              I actually used it like that for about 1 year or so later reverted to stock. I manage to scrap the engine scoop part once when I was with a pillion and rode over a big hump while parking the bike ..

                              I did it in order to reduce the stiffness as it hurts my lower back. Later became back to stock settings as the bike looks low and handling wasn't as sharp as its meant to.
