    Tank mounting advice

    Yes...I know this a common thread of "how do I mount my fiberglass (insert part here)"...but I've been scouring the net and haven't found anything too useful yet.

    So, here is my dilemma. The vic camp style tank I got from Airtech is sweet - but doesn't easily mount up. The studs in the front are super low below the frame backbone and it would require a very funky mount...described below. But, am hoping you lot have some more creative (and potentially cleaner) ideas.

    Photo of the tank and seat lined up...


    Photo of the front mounting studs...


    Underside of the front mounting studs and backbone...


    Old tank mounting holes...


    From the front...



    So - in picture 3 you'll notice that there is a brace between the front down tube and backbone. At the back of that brace is a slot that is typically used to mount the coil. I could fab up a bracket that is a reverse A to connect to the two studs and fit through the coil bracket. However - that seems like a big ass bracket and kind of clunky. I spoke to Dutch at Airtech and he thought that might be the easiest way - but I just don't dig it.

    Option 2 (not really sure if its an option or not) is to mount tabs on the front of the tank and use the old tank mounting holes that are in the frame (photos 4 and 5). But I don't want to stress the tank - and little tabs glued onto the fiberglass probably wouldn't be very strong.

    So - any ideas I should consider?

    Cheers,

    I was thinking option 2 as I read/looked at pictures. Perhaps if you fabricated a bracket that bolted into those front holes, curved over the backbone & attached to the lower bolts on your tank... like a big saddle over the top member of your frame.

    I would fab up a metal strap that hooks onto bolts or studs on the original mount holes on your neck in the front, and then bolts down in the back, with some padding in the channel to isolate it from the frame.

    in my best ascii art form:

    Code:
                                  strap
                   /-----------------------\ 
                   |  |-----------------|  |
                   |  |      tank       |  |    <-- bolt here
    bolt here ->  O|  |-----------------|  |__|_

    I wouldn't do that. I'd scrape that pretty paint off the frame and weld on a t-bar below the horizontal tube to use the tanks mounting studs. Rubber mounted, of course.

    don't some older race bikes use a tank strap?

    Yes, but you need a good base to hold the tank to. He doesn't have that.

    Unga - the only thing I'm concerned about with that idea is I still have to make sure the motor fits! Keep in mind that the top of the head will literally be right up underneath the backbone (sorry I didn't mention that before). Hence, the bracket would need to come out at an angle, or mimic the shape of the underside of the tank all the way down to the studs.

    Judey - not a bad idea...as long as its slim enough it will fit through the channel, just need a twist at the bottom to make the bracket horizontal to the stud when it comes out of the bottom of the channel. Hmmmm.

    Keep the ideas comin'!

    This is a CB350, right? Then you should have some room as long as you relocate the coils.

    I think this is a duc, Unga.

    perhaps like this (flat view, and bent view)

    Yeah - its a 65' Ducati 250. Hard to tell without the motor in it! :-)
