hi....i'm somewhat confused by the contents of my tool kit

anyone able to enlighten me as to the function of some of the tools?

got a metal tube that looks like a tank has run over it. is it perhaps a handle for those hex socket spanners?

what size is needed for the front fork pre loads?

a 24 grips but is loose...can imagine that after a while it could round off the adjusters after some time.

the flexy wrench....i've found a few bolts that will turn with the smaller end...and worked out it fits into a longer piece to allow for better access for harder to reach bolts (though cant find any hard to reach that may require it yet) and the only thing that fits the larger socket seems to be the spark plugs.

now. as said above...seems that tube is a handle for thesewrenchs....wrenchs used for the axel when loosening to adjust the chain BUT.....why is there only one? i've tried (albeit half heartedly) and i cant get any grip...can just make the assembly move, but not loosen (i feel weak)


now.....
surely in the bike tool kit, it wouls give you what was required to do all the simple tasks...but of the slightly more difficult ones, you lack the tools....eg, is there a tool to take off the main bolt on the tank? as most work requires the tank lift it seems

i kinda share my dads workshop...so got all tools i need.
just think the kit colda done with a few more sizes of wrench and spanner.




so....the enevitable request for advice i pose to you on THIS day...what do you reckon would be a sensible addition to my humble tool kit?
