"Finally" I got the GT back together and took her for a ride. New Power FRK installed. New audio stuff (Sony Walkman X-Series with gold-leads back to Autocom). Nylon 1/4" standoffs on that servo on the throttle body with longer screws. Metal quick-disconnects to replace the cheap plastic ones.
Took her out for a 120 mile spin since dealer installed new software and new airbox, which took a month and prodding by BMW NA who's tech installed it. The dash clock runs in 12 hour mode now instead of 24 hour mode. That's different.
Some problems were gas tank grew a bit in the 103 degree heat and would not fit into the bike. That part is my fault for sealing the tank's vent while waiting for sealant to dry. Some hot towels and a bit of vacuum took care of that over two days of work. No visible leaks showed up. Body panels are a bit tight though since the swelling, but all screws went in. Oh well.
Test ride with Power FRK is amazing! Very smooth. No flat spot at 3200 RPM when cranked up. Slow speed was smooth as well like the bike should have been beforehand. So smooth I imagined I was smelling a rich fuel mixture off the pipe. Turns out I was - except that it wasn't off the pipe, the damn bike's gas tank is leaking somewhere.
Yep. Once home in the garage, I saw several drips on the floor showed up quickly and I smelled it. Damn it! Gasoline!
Left side is covered in fuel splash, and you can see it on the rubber foot shifter too.
Lifted the fuel cap to depressurize the tank. No "Whoosh!"
sound so I guess the vent is working. The only thing I can figure is the new quick-disconnect is leaking someplace since this appears to be a pressurized leak. I have the Viton quick-disconnect, but it seemed very loose when I plugged it into the receiving end in the tank. The older plastic one is much tighter, now even squeaky tight since it has dried out. The O-ring on the older one seems to have swelled or be a bit larger than the new metal one. I hope BMW hasn't used one of their magic swelling O-rings like they used on their older RT gas tanks. They were they size of a pencil when new, but swelled up like a donut once gas hit them.
I may call the outfit that sells the metal ones and ask in the AM about getting some more O-rings or different sized ones that may seal better. A fan is on the bike now since I don't want to jerk the battery (sparks) until it dries out and cools down a bit.
Will await the "tank pull" to see what is leaking.
