2. The OEM pickup tube flops around in the bottom of the tank. Any point in trying to orient it in a specific direction? Prior to the rebuild, I'd run out of gas even with a gallon or two sitting in the bottom of the tank - not just slosh, I just dont think the pickup was sitting at the bottom of the tank.
First of all NICE work man!! In chasing a high speed stall I have on my '89 with the 351 (in another thread), I have dug into my gas tank to look at the pickup. When I tried to separate my anti-siphon, I snapped the fitting off. I actually did not know it had one until a ball & spring shot out. My pickup is different than yours, mine is a straight piece of hard plastic tubing, with a filter on the end. The filter is about a half inch off the bottom of the tank, about in the middle, which I think is probably the best place for it. I'd try to land your pickup in the middle of the tank, or better yet replace it with the original setup. When I replaced my anti-siphon and the special fitting between it and the pickup tube from my local MC dealer, I was pleasantly surprised they had them in stock. I'd recommend going back to stock pickup, I'd bet most of the MC dealers have it, or can get it. I should have taken a picture of it all, oh well. One of the ways I may try to fix my high speed stall is temporarily removing the anti-siphon, but I would guess that is not my problem, or yours either. I have run out of gas and there is about an inch of fuel left as well, but I don't think there is a good way to pick up any more fuel than that.

Is your gas gauge working? If not it may be your float. My original one failed a few years ago, so I replaced it with one from skidim. It bolted right in, and after a few adjustments to the level position, it is right on the nuts.
Good luck with the rest of the project! So good to see one of these old steeds coming back to life!

Worked on the exhaust... installed new silencers (in-tube, -8.4 db) to try and quiet her down a bit.

Put the windshield back on, and bent the ND tower to fit (it was a bit out of calibration - it takes a lot of force to bend it back into spec - I used a tiedown strap to pull the rear in, and a ratcheting cargo bar to push the front legs out .75 inches each, respectively.

Used a 1 inch forstner bit to drill through the gelcoat down to the glass.

Hmmm... there seems to be a support member in the sidewall of the boat, right where my reinforcement plate is supposed to go. Think I need to call NDT on this one

Did you run a bead of sealant along the hull/top seam?
