Looks good! Although I treat my machine as a tool...not too concerned about the look:
Lookign down @ idler (notice slight bend):
Tire clearance (I agree with 2door: get slicks...ESPECIALLY for the rear...the chain will chew away at the thicker-tire):
Down-tube mount (looks ugly, but it's trouble-free...ALWAYS get the seat-tube saddle flush if you can):
Note that I have a shorty intake-plenum...it would have been impossible to fit the engine otherwise. Also, I replaced the stock rear-wheel with my own custom quick-release hub and @ 36-spokes. That Walmart hub WILL deteriorate quickly.
