I wanted to dish out the sides of the tank, so I cut out the shape I needed.
This gave me great access to the inside of the tank. This was the best time to clean out the rust and hammer and dolly the dents.
After all the cleanup work was done I started to make the panels that would fill in the sides.
Panel by panel, the tank is filling in.
I was making one panel at at time, working from side to side to make sure the tank was coming out symmetrical.
All panels on both sides are tacked in at this point. I just need to weld them in fully.
All burned in!!! Just a little clean up, pressure test, and time to start getting ready for paint.
So I started out with the original gas tank, and exploded it into a steel beach ball (hopefully the first and last time I do that). I did want to use the tank however. Lucky my local motorcycle salvage yard, Southwest Motorcycles, had what I needed!
I then started out with another stock KZ750 tank. From there I had a little work to do. The new used tank had some dents as well as some rust to address.
Here is the new stock to be used for the outline of the mesh. I weld the ends of the stock to a piece of scrap.
Next I cut 1/8″ grooves along the new stock. The mesh will sit in the groove.
Here you can see after I cut the grooves I bent the stock into the shape I need.
The grooves stay intact and hold the mesh nicely! This is the front.
Here is a inside view.
Before and after.
It was mainly the inside of the piece that was bothering me. I didn’t like seeing all those tack welds.
Here is the inside of the left rear set.
And this is the inside of the right rear set.
Front of the right rear set.
Front of the left rear set. The rear sets aren’t completely finished, but are %100 better than before.
So, I was working on the frame and just was not happy with the mesh accents on the rear sets. I like the look, but was never really satisfied with the way I had attached the mesh. The tack welds on the inside of the rear sets demanded too much attention.
I chopped off the old and set out to make a cleaner way of attaching the mesh. Now the mesh is basically framed in, instead of welded in. It makes for an much cleaner look inside and out. I was so hyped on the way the second attempt turned out!!
So I wanted a fender that only mounted on one side of the fork. The original design I came up with seemed good enough, after all there’s not much of a fender. While off loading the bike one day I heard the fender make a “tin can” sound. Needless to say that drove me nuts. So back to the drawing board I went. I made the front of the mount more robust. I knew I also needed to stabilize the rear of the fender. I made a detachable strut that wraps around the fork and mounts to the rear of the fender. I decided to wrap the strut in fiber glass to save weight. The fender now has the rigidity it needs to keep things quiet.
I started out by making some rough marks where I wanted to cut. At this point I’m just trying to get a idea of where the lip is going to be.
I made a rough cut with the plasma cutter. I cut around the gas cap mount in order to reuse it on another tank.
I cut out a shape I thought would work for the lip and added it to the back of the tank. Then I massaged the opening to fit. I then added the new gas fill opening in a new location. All that is left is the top.
I then cut out the top of the tank. A little shaping on the slip roll and it dropped right in. This is the tank all burned in and pressure tested for leaks.
This is a 05-06 Kawasaki 636 tank I had hanging around the shop. I bought the bike for parts. I used the majority of the parts on a KZ650 build. The 636 tank was not going to be used, so I figured mod it out and sell it.
