    Fuel Tank Rubber Isolator - Interest Check

    Hey gang. I'm in the midst of talking to a company about making new cast polyurethane fuel tank isolators for the OEM tank.

    Right now I have no idea of price, but of course I will do my best to make it reasonable. I think I can target ~$40 a set, but don't quote me on that until I have more information.

    I made 3D models of the front and rear mounts so I should be able to get quotes from several places.

    I would like to have a few dozen sets made in the first parts run. Let's say 36.

    So, the million-dollar question. Who would be interested in a set?

        Put me in but frankly I am a little sceptical. I'm wondering if urethane might be too stiff. I have to mash the front one pretty hard to get the spacer to line up.

          should also think about the upper units so the tank does not rock back and forth on the frame!

            bk94si I'm going with 40A durometer urethane, which should be similar in hardness to the OEM parts (I'm using a brand new rear mount as reference). If that turns out to still be too hard I'm pretty sure I can get even softer urethane.

            nt650hawk not sure which part you're referring to? The pieces I'm working with are #22 & #25 in this drawing. The side rubbers, #25, I figured could easily be replaced with some rubber tape or edge trim without needing to be reproduced exactly.

                            I think the problem is that the aluminum frame flexes quite a bit under load, so the big rubber wedges (which you refer to as the "side rubbers") are needed to support the gas tank, in addition to the front and rear mounts.

                            Is it only the front tank rubber that is no longer being produced by Honda, or is it now all four rubber parts?

                            In any event, I will need a new front tank rubber soon, so I'm on board.

                            PS - I second Bk94si's concerns about the needed pliability of the front tank rubber. You really have to ram the tank into the rubber to get the holes to line up so you can get the tank sleeve back into the hole. Even at that I had to use a bit of cable lube to reduce friction so the tank rubber didn't grab the tank sleeve on the way back in!

                              The side rubbers aka #23 are still available and as mentioned above, can be replaced with a few other options such as fuel line with a slit in it.
