The Honda PA 50 is a 50 cc, 2 stroke moped with a Continuously Variable Transmission (CVT).  The CVT works like a snowmobile tranny, as the rpms climb, the gearing also climbs.  One of the PA 50's more notable features is the decompression lever which makes no noticable difference as most of the resistance to pedalling comes from the belt drive and gear reducer on the rear wheel.  An interesting fact is that the 49cc motor is almost exactly 102 times smaller than my 5.0 mustang motor.  More interesting is that at approximately 2 horsepower, the 49cc motor is putting out almost the same amount of horsepower / liter as my mustang; 40.8 hp/liter for the moped, and 45 hp/liter for the mustang.

                                                          The Story of my PA 50

I got my moped in the fall of 1997, it cost me a set of slightly used 14" tires.  It didn't run when I bought it, and the piston was siezed from sitting for so many years.  My friend Isaac and I pulled the head off and wire brushed the carbon off of the piston.  We then sprayed the piston with WD-40, let it sit, and then cranked it over with an air gun.  The ped still didn't run, so I took it to my mechanical guru Dan.  The problem, as Dan figured out in about 10 minutes, was a bad condenser.  I got a new condenser for $10 from a salvage yard (any condenser works, the one I got was from a yamaha) but the ped still didn't run.  After cleaning the carb and petcock, the ped ran.  It would do 30 kph (19 mph) and it ran like crap. The problem was that I didn't have an air filter (engine is tuned to have an air cleaner), and the pipe was pretty plugged up.  I attained a parts moped which was almost complete for $20 (starting price was $100, it didn't take much to get the price down) from a branch of the salvage yard where I bought the condenser.  The pipe and air cleaner from the parts ped made my good ped into a smooth running machine.  I decided I was going to fix it up, so I sanded both fenders, the gas tank, the rear luggage rack, the lower subframe, the upper tube frame, the kickstand, the liscence plate holder and forks down to bare metal and had my friend Mike get them powdercoated.  Mike worked at a powdercoating plant, so it cost me 3 cases of Bud for the powdercoating.  While the parts were being powdercoated I buffed almost every piece of aluminum and chrome on the ped as well as almost all the bolts.  While it was apart I cleaned and greased all the bearings which I would highly recommend you doing if you plan on keeping your ped for a while.  I got the parts back from powdercoating, bolted the thing together, slapped some SPY stickers on the tank and some flames on the luggage rack, bolted up the motor and it started up right away which surprised me a little after having it completely apart.  Something else I should note is that I am 185 lbs which is 5 lbs over the 180 lb load rating for my moped, so your moped may go faster than mine with equivalent mods (take a look at the different mods sections).

                                              Driving Impressions of my PA50

Driving a moped requires a slightly different attitude than when driving a motorcycle or a car.  With a moped, not only can you sit back, relax and enjoy the ride, you MUST sit back and relax because it's going to take a bit longer than with a vehicle with a respectable amount of power.  You must be able to laugh at yourself, or else you'll be the only one who isn't laughing at you.  In spite of, or maybe because of the lack of power and the laughs, a moped is a blast to ride.  Nothing around you, no stereo, no power, forces you to look around and enjoy the ride.  Unlike a motorcycle, which most people are not very fond of, most people have fond memories of mopeds and enjoy seeing them.  My moped accelerates pretty hard for a moped, and it handles incredibly.  My riding buddy is my friend Isaac who has a 1979 Kawasaki KZ650SR and, needless to say, his bike is a bit faster than my ped.  When it comes to corners though, Isaac slows down, corners, and accelerates after the corner, whereas I keep the throttle wide open and lean over till I am almost parallel with the ground.  I have to corner hard to keep my speed up, but it's fun cutting corners hard.  Riding up hills I have to pull over into the bike lane so as not to piss off even the slowest drivers.  Gas mileage is very good, I've never actually measured how far I can go on a tank, but I know that a 10 liter gerry can costs about $5 Canadian, and my tank can hold maybe 3 liters.  So if a tank lasts me a week, I can go about three weeks on $5 of gas.  I wouldn't recommend a moped as your number one mode of transportation unless: you live far away from any hills, everywhere you need to go is fairly close to where you live, and you never need to take anything large along (nothing bigger than a backpack).  I use my moped as a second vehicle for when I have lots of time, and it saves me lots of money on gas as my first vehicle is a 5.0 mustang.  (update: sold mustang, am now looking for Suzuki Savage 650, or Intruder 800)

E-mail me at the top of this page, I'd be more than happy to here of your modifications or speed tips; Make sure you explain them in great detail so that I can try them and post them.  You can also send me pictures of your moped if you'd like them posted on my page (any moped is fine) and please also send all the specs on your ped so that I can include them with the picture.
