It looks like the stock tank is going to be the only way to go for now. Everything else is either not that much bigger (IMS), not being made (Clarke), or goes outside the frame rails and gets in to the radiators (IMS and Acerbis). The stock tank lists capacity of 1.7 gallons, but that includes the fuel pump. I think it will be closer to 2 gallons once you factor in the fuel pump being gone. I'm going to do a capacity check before my first ride just to be sure. I attached a couple of shots of the new look. I really like how sleek it looks with the stock tank. I just hope I don't have to push it home some day.
While I was visiting my parents, I was able to get my head stay completed; it only took me four attempts. Not my best day in the garage, but I was finally able to make a really stout 3/16" bridge that goes above the head and holds it just like the stock two stroke head stay. I'm going to paint it this weekend, and I'll post a picture when it's done.
The radiators are going back to ICW for some more modifications so they will clear the frame and allow me to move them back to clear the triples. Two steps forward, one back. I'll get there soon...
