There are 2 plugs, one for engine oil, the other for transmission/primary drive oil. Both are underneath the engine/transmission case near the kick-stand support on the left hand side.

i found the drain plug on my 2.4L under the exhaust manifold. These cars are ridiculous to work on :(
remove the drain plug between the exhaust under the motor
Run till engine is hot. Park and shut down. Place drain pan under drain plug, underneath engine case, forward of transmission lube drain plug. Remove drain plug allow to drain fully. Replace drain plug. Place drain pan under oil filter. Remove oil filter. Replace with new oil filter half-filled with fresh oil. Add oil to filler opening until level reaches midway between "Full" and "Add" marks on dipstick. Ride, and check level. Add as required. Grin, ride, lean, love, LIVE!
Its an hexagonal plug below the exhaust manifold on the side of the engine.
Greetings, The spark Plug is located on the left side of the bike (if you are sitting on the bike). It is under the gas tank. Let me know if you figure out a wat to replace it. I am still working on that one. To clarify the above: The spark plug is accessed from the left side of the engine, atop the cylinder head. There is one spark plug. Access for replacement is very easy. Put a wrench on it and turn it counterclockwise to remove the old spark plug, then apply a slight film of anti-seize compound the the new spark plug's threads, carefully hand thread the properly gapped new plug into the hole, then tighten it to the specified torque using your wrench. For all the Buell Blast and other Buell Motorcycle related information you can stand, check out the Buell Forums on BadWeatherBikers.com and especially the excellent Thumper Forum; see following links. :)
It's located below the exhaust manifold.
Warm engine. Place drain pan under drain plug. Remove drain plug (one for engine, one for transmission/primary drive) Remove and drain filter, again with pan underneath to catch oil. Install new filter. Install drain plug(s). Add new oil and verify level per owners manual (see link below).
The oil drain plug is near one of the two exhaust manifolds (passenger side).
Exhaust side. Bottom face of bearing door (stamped BAKER on the top) facing towards the exhaust pipes. Two mounting bolts with the 3/16 Allen Drain plug in the middle. It is part 51740-001.
