Here it is with the seat off and the clamp slid down a bit. I put two slits (one cut) in the seat post about 3/4 of an inch down. I had to add a spacer so the clamp would fit and I put a slit in it all the way through. Works great and if somebody 7 feet tall wanted to ride it I could probably raise the seat high enough. Any shorter than where it is at now and I would have to take some off the stuck post.
Here's a whacky idea....why not have the shifting done by a mid-ship or back seat rider?Sprocket swap has been completed and the rack is mounted. I also got my long spring Messenger set up. If the seat post clamp seems a little high that is cause it is. The seat post was REALLY stuck. I have been alternating between Aero-Kroil and PB nearly every day since the BO began. I have also tried heat and had no luck with that either. Finally I realized that the old school seat post already clamped to the seat was a perfect fit to slide right into the Worksman post. All I had to do was cut a couple slices down the old tube and slap a clamp around it.
Does anybody know where I can get a REALLY, REALLY long shifter cable for my 4 seater?
The bike is hard enough to ride as it is and it will likely be used to give rides to inexperienced riders rather than the same 4 guys taking it out all the time. Besides I'm a control freak and other people's judgment isn't always easily trusted.
No not really. They usually get the outer housing on a roll but the cables tend to come with the balls and barrels already on them at specific lengths. My LBS can get a tandem cable but it is not nearly long enough.
Not only would it look cool, but it would get around the possible problem that kingfish mentions of cable taughtness over a long distance. 
That would look cool but I am not really sure how that set up would work. Would there be a cable at each end with a solid linkage in the middle, or are you thinking solid all the way? Wish I had a picture of something similar.If it were my four seater, I'd go with solid mechanical linkages.

Time is starting to feel crunchy around here. I have a lot going on the next several weekends so I will be trying to get finished up before the deadline, hopefully. I got some paint on the rear rack and mounted it up. The rack also doubles as a motor mount so I figured I would try bolting the motor in place. The motor itself is B&S 5 horse but the cage and prop are off a Dragonfly air drive boat motor. One of my big worries was that the motor would be too heavy behind the rear axle and would cause unwanted wheelies. Not really a problem but I was prepared to fill the bars with bbs.
I don't know yet but as soon as I get the throttle and kill switch hooked up, I will be giving it a test run.
And yes, I will take video.
