Fuel tank bolt size

[Mike]

The bolt that runs into the back of the fuel tank to bolt it to the frame was not on the bike I got it. Any ideas what size it is so I can go get a new one?

Mine has a 13mm head, so I think that makes it 10mm coarse thread (I think, not positive there), anyway, the metric equivalent of a 3/8" bolt. My mind isn't pulling that stuff out of the murky recesses at the moment, but it may point you in the right direction.

I do not know much about machine screws and bolts but the part number is
01500-08307

the second half of this decomposes to reveal 8x30?

Is is just a bolt and a nut going through the tab on the tank and the frame, or does it bolt straight into the frame?

Correct. Most of the stock numbers for bolts have the size embedded in them. 8mm x 30mm in length.

Take a look where it goes. My 750L has a captured nut that the bolt.....uhmmm....bolts to with some rubber washers. If it's been jacked with, just get a bolt and nut that fits. As long as the tank is secure, it doesn't matter all that much.

Perfect, thanks!

And even if it isn't, it doesn't really matter either, my bike has lived half of its 30 years without that bolt, no problems, the rubbers in the front and the seat holding it down at the back hold it pretty snug.

Mike .. tank bolts go into a nut that is welded into the mounting area on the frame.

Yeah, mine is relatively secure right now, but I figure I might as well snug it down when I get around to it.
