Since my bike will have the old school look that means no speedometer**, gas gauge or anything. Basically everything will be stripped except the wiring to run it, start it, and keep it legal; i.e. headlight and break light. We can argue safety later. I rode a GREEN crotch rocket that was never seen. This bike will be heard far before it is seen.
Anyways I digress, a really cool feature is to have a 'visial' gas gauge. The steps was to order a couple NPT threaded bungs that I got from Bung King. Then some brass angles and clear tubing from the local hardware store. The total cost was at $16, much cheaper than a $36 kit.
- It loses some of the integrity and strength in the backbone, which is VERY minimal.
- The main reason: these twins vibrate more than an ant experiences during an elephant stampede. As a result many gas tanks get cracks and leak.
I felt the only option was the option my dad believed in as he would say, "Nothing should be done half a$$ or mickey mouse!" To over come the strength issues of losing integrity I got some blind bungs, meaning the bungs did not have a whole all the way through. I chose these because that way water could not enter the bung through the threads and get inside the frame. Here are the bungs I used, I used metric threads to match the metric bike. To overcome the sencond concern, I went down to the local hardware store and found some perfect grommets ans some stainless button hex bolts as seen in the pictures.
