Last Saturday I delved into the depths of my motorcycle to clean out the carburetor. The bike was running OK, but the low end was a bit jerky and sluggish. So, sure as "parts is parts", I rode the bike that morning to my buddy's shop, home of all the tools of the trade. Despite my insistence that I could probably do most of it myself, he realized that I didn't even know how to remove the rear fairings... so he gave me some directions and a phillips-head and went to fetch a wrench. Turn turn turn pull-flump. Pulled out the gas tank, which for some reason doesn't leak when you pull the hoses out. Disconnected the throttle and choke cables. Hmm... looks like we'll have to pull out the airbox, what a pain in the ass-- and then with a bit of magic he extricated the carb from the impossible space between the engine and airbox.
He did most of the work inside the actual carbs. Drain valve? Nah, let's just unscrew the float bowls and let the gas pour out. Unscrewed the jets and put them in the float bowl along with the screws, and pour in some cleaner. Damn, that's nasty, the mixture is turning green. Flip through some magazines about American cars while the chemical does its thing. Then we put the whole thing back together, which took about half an hour. Cranked, started, and she was good to go. He took it around the block to make sure it was working alright, and then I rode home.
In all, not only was the low end much smoother, but I didn't realize how anemic the top end had gotten. Now it's smooth down to 2000 rpm (near-stall for a 14k redline), and the throttle doesn't have any choppy points. Well worth half a day. I really owe my buddy for helping me out with that.
Got home and I wanted to take a shower to wash off the sweat from riding and grease from wrenching, so I hopped in the shower and turned on the tap... one thin high-powered stream of water. What the hell? Switched the faucet over to the bath tap and a bunch of nasty silty crap came out. Fantastic. Out came the phillips-head again, to remove the shower head and clean out the shower jets. Hey, there's a grommet here too. And a bunch of rusty silt-crap, force-rammed into the jets of the showerhead. Easily fixed; just reverse the showerhead, hold it in place backwards, turn it on, and let the water pressure blast the crap out. It worked, but only after a lot of gentle prodding to loosen the dirt. And then, finally, screw it all back together (deja-vu via reassembly) and finally take a shower.
