Here's my bike...Project Incognito...1996 Raliegh M-80 with a Grubee Skyhawk 66cc. Gas tank is off of a weedwacker and side covers are self-made of .063" Aluminum (5052-H32). The side covers cut the engine noise down a bit. I am currently working on a hidden gas tank in the tubing of a rear rack. I found a rear rack attaching to the seat post from Walmart for $16.99 and I'm going to modify it to hold gas (i figure I'll get around 10 miles worth of gas out of this size container).
