I have a 1980 CB750K that I'm working on. This is my first motorcycle and my first time really doing anything mechanical. I'm turning into a modified cafe/brat thing. So the past couple of days I have been working on knee dents. Tonight while I was banging them out I noticed it was getting wet. I thought it might have been mineral spirits from when I was wiping off the dust. I wiped it, hit it some more and it got wet again. I was wearing a mask so I didn't smell the gas then it dawned on me. The tank has a crack where the badge originally was. Same thing ended up happening on the other side. It had some kind of filler in it from the previous owner taking the badges off when he painted the bike. I either sanded through the filler or cracked the tank by hitting it. So question number one, How do I fix the crack? I've read things that say to solder it. That sounds the best to me but I'm open to suggestions. What kind of solder would I use to do that? The crack is about 1/4" long.
Part 2: After all that stuff happened I went to put the tank back on the bike to see if how it looked on the bike and I couldnt get the tank to go on. The spacing between the sides of the tank got pushed in just a little from me putting in the knee dents. What do you recommend for bending it back out? I have a little piece of wood between the things that hold on to the the rubber parts on the frame to try to push it out a little.
Otherwise the dents actually look good to me. I was nervous to try my hand at metal work but it pretty much shaped it's self. I just need to get these problems solved ASAP so I can get my bike painted before I have to go back to work. I'm on leave right now. Thanks in advance.
