Yamaha V Star 650, KJS single carb mod tig weld in single back bone

I have a 2000 V Star 650 which I have Bobbed .

I came across this V Star on youtube and said WOW…I want to do the same with my V Star. (props to Uptown Customs and Rob)

I did my research and discovered in order to change the huge gas tank I had to deal with the air intake box under the gas tank,


I looked at the Uptown Customs V star and discovered it had a single carb setup and which seemed the only way I could do away with the airbox,
Mods needed :
1) replace stock carb system with single carb system.
2) Cut out and remove the double back bone and tig weld in a single back bone to mount gas tank.
3) Reposition speedometer
After a google search I came across the custom KJS single carb kit for Yamaha V Star 650 which costs a hefty $ 670 delivered. Before I did anything I researched the KJS system and found this write up.

Spoke to the guy who designed the system named Ken and he explained the details about his system so I ordered the kit.
I have been learning tig welding and can weld ok, I will continue to practice tig welding and when I feel I am good enough I will consider tig welding in a single back bone .
Planned design for single back bone

Please give me feedback about the back bone design or any feedback…
