The plate in this picture bolts directly to the seat/fender mount "horns" on the frame. These two hoops will be joined by two straight pieces. I need to wait for the stock bits for mounting the rear of the fuel tank before I can build the front of the mounting frame. The front of the seat and frame will tie into the rear tank mounts.

It wasn't clear how big or small it was in the ad, so I am pleasantly surprised that it fits the size of the tail so well. It is 5" tall including the license plate bracket - I may need to increase the bend angle on it to clear any interference with the tire.

You really have to be wary buying parts off of Flea-bay. The clutch lever holder was broken on this bike. I found a couple replacements on that site, but almost all were questionable cosmetically. I finally found one that was really clean except the lever was bent. The lever that came with my bike is straight and clean, so that wasn't a concern. The part arrived today and what was shipped was severely yellowed, and clearly was not the part pictured in the ad. Needless to say I left a negative review on the seller, and sent them a message voicing my displeasure. I am going to try and clean it up, but misrepresenting the part you are going to ship is BS!!!

Not to hijack the thread, but...
Badwolf said:
"Tubeing is stronger than solid round bar,& lighter too"
Absolutely not true. Tubing is stronger than solid of the same weight, because the solid would be much smaller OD. In the same OD, solid is always stronger. The air inside a tube isn't stronger than solid steel.
The strength of tubing increases as does the square of it's diameter. So, given the same weight, you can get some seriously huge diameter tubing that is stronger than the same weight of small OD solid.
Common misconception. But, air is not stronger than steel.

I was going to say that, but was looking for a cooler way to say it so it stuck.

Like...
Pound for pound, it's true a 2" dia tube can be a lot stronger than a 1/2" bar and weigh the same.
But a 1/2" tube versus a 1/2" bar, no way.

You remember the cargo door fiasco in the 90's?
I had a hand in fixing that. Turns out they were forcing the door lever to lock the doors. The door bolts where operated from a central handle by 1/2" thick walled tubing. It didn't take much to cause them to buckle. When I got thru with it a 300 lb monkey could swing on the end of the handle and not buckle them. And only a 1/2 lb heavier.

ALL RIGHT! TUBEING WAR!
I have to guestion what you mean by strength. Tension, torsion, shear, or resistance to bending? I said to go with 1/2'' tubeing rather than 3/8'' round bar. The inside of a round bar is it's weakest point, the surface is the strongest. Because of the greater surface area, larger od and inside surface, I would go with the tubeing all day for resistance to bending.
We need Dave (a engineer ) to weigh-in on this one.

Thanks!

A little about my background... I spent the last 24 years of my working life running a metal fabrication shop as production and quality assurance manager. We did commercial and aerospace work. Contract manufacturing. I certified four of our welders for aerospace, and we were welding on patriot missle parts for Raytheon. So I will enjoy reading about this tube war. Hijack approved! This should be fun!

I went with TC Bros flat track bars. Luckily they were shipped using a foam sleeve over them as the box ended up looking like it had been run over by a forklift. Thankfully they arrived straight and undamaged, which is more than can be said about that box!

So I totally screwed up. My fork caps showed up from China. Search as I could, I could not find a source to ship from the US. Well, I ordered the wrong ones. Same diameter threads, but a different pitch. My bad. I think I will be hard pressed to get a return or a refund as they are not damaged and it was my fault, so I am out $25. The plan was to have them by the time the handlebars arrived so I could measure and plan out the risers. Now the bars will have to wait for the right fork caps. Sigh... Embarrassed

Dave makes targets.

All have to be considered.
In tension, pound for pound, tubing is the same as bar.
Torsion, tubing has it over bar.
Bending, tubing has it over bar.

More wt., more material, more strength.
The books are under the monitor, don't make take them out.
