Thanks again James, The seat "springs" are a flash of genius. Very clever. You certainly have the skills to do these bikes. I like the set up for the handle bar limiter. Mine has two little rubber padded screws to stop it but they are about useless. I'll intergrate your design into my plan. Making the jackshaft mount a part of the engine mount is a great idea also. Unfortunately, I have to have all my machining and welding done by others, not much equipment to work with metal here. I do mostly woodworking in my own shop. My local muffler shop has been great about welding things for me, I just buy him a case of beer now and then. I was a patternmaker during my working life but that too was mainly wood, there is a pattern shop near me that has been kind enough to do some minor machining for me. They can't allow me to use any equipment of course because of liability concerns. I take the whole crew there a couple of dozen doughnuts now and then as a token of appreciation.
You're absolutely right about an external fuel filter, both my cruisers have them and I will get one on this bike somehow. The tank on your bike is different than mine, having more of a downward angle, mine goes straight back toward the seat along the frame line. I can get the shut off in ok, it's just poorly positioned for this particular bike. I will switch tanks with one of my cruisers as they both have different tanks that will work better. I used teflon tape on my shut off valves, no leaks so far but I do have gas proof putty as well.
Before I mounted any of my tanks, I filled the tank with small stainless screws and nuts along with some very course sand. Then I strapped it to a paint shaker for awhile and it cleaned any rust out beautifully. I made sure I did a very good job of cleaning the sand out. I've had all my tanks chrome plated inside.
