Gen 2 Frankentank

That bike belonged to the late John Ryan. The tank held 13 gallons + and I suspect was the inspiration for the IBA rule dealing with the rear profile.

I met up with John in Key West, FL at the end of his 96 hour UCC ride from Alaska.

I don't remember John mentioning anything that Devil's Mountain getting in the way of the bars, but he did say that it made a great head/chin rest on the IBA rides

Did I miss something here? Chuck can you explain the whole 10 gallon versus bar thing to So Cal Ha Ha!

 

[Chuck35]

10 Gallons is about the limit to be had by upward expansion. With MCL risers the grips just clear the tank. In fact one quickly learns to rotate the thumbs upward around the grip when steering to full lock.

So the grips limit the top. Turning room for the bars limit the front. IBA rules limit the back. The bottom is limited by the airbox.

We have but 2 possible paths for further expansion, wider or modified airbox.

I wonder if I took two 3/4 gallon pieces of play dough could I make them attractively fit the sides?

Mine was Jim's first build where the bike had a replacement triple clamp. While this gave us more room above the tank, (than riser adapters) the front was tighter.

He had to "take another whack at it".

I wanted to replace my Helibars clamp with a MCL one due to MCL's increased forward grip rotation, so I had the new one shipped to him along with my tank.

So who is going to be the first FJR owner with an 11.4 gallon frankentank and APE HANGERS. ?

 

[Big-B]

Maybe we can get another gallon or two of gas in the ape hangers.
