Get some rings, when I bought my Peugeot 103 it had worn rings, the new rings had to be hand sanded down to fit in the groves of the piston. Well of course I broke one trying to expand it over the cylinder and first ring groove. So I put the last ring I had on the top.Now here's the dyno results: With worn rings 23 mph, with one ring 25mph, after I ordered another set of rings and hand ground

Whoa-nelly-great-horny-toads! STOP what you are doing. By no means put synthetic motor oil in a tranny. There are synthetic oils out there that are formulated for transmissions. Mobile one and other synthetic motor oils are made for engines. I have seen so many of my dirt bike friends fry their clutches because the synthetic is too slippery. Even when they take out the clutch plates and put them i

The last thing I read about side gapping was that it changes the flame kernel. If a standard plug fires, the flame has to go around the gounding electrode, in the millionth of a second flash this slows the flame down. I have made plenty of side gapped spark plugs and they work. Air planes for years have used surface gap plugs, becuase they run at a low speed and 75% power at all times. Mazda Rotar

2 stroke pipes in the old days could be taken apart, sometimes the entire center core could be pulled out. Look for rivets, you can drill them out and hopefully remove the baffles. Its a matter of flow, you can drill the baffles larger or drill more holes to improve flow. You will have to rejet, the second the flow goes up the bike will lean out and that will kill power and if it leans out too muc

Everything I say somehow relates to a story, I used to have a Peugeot 103 and Cimatti that I was given as a basket case. The Cimatti had great low end torque and could blow away my 103 which was tuned for 40 flat out. I got into porting the brains out of the Cimatti, it killed the low end torque, my 103 was now faster out of the hole, but the Cimatti did about 43. Mind you the Cimatti had an auto

My 77 103 would usually clog the little filter in the fuel tank, it was a small brass screen, I also put a small fuel filter on it. The carb is so small it can be clogged by many things, the vent pipe, varnish that builds up, water condensation in the carburator when the engine is shut off. So its tank, fuel filter, carb. Don't be afraid to put in a cap full of fuel system cleaner, before you

I used to carry a 6 oz. bottle of oil in my Peugeot 103 tool kit box, ran it at about 40 to 1 or less. That ratio kept my plugs clean for a while. I always carried 3 spare plugs too, course I was known for my 100 plus mile road trips. I always fueled up at a gas station and just added my own oil. I always used 30 weight oil, but now adays I mix in 50% synthetic, which makes the ped run better. I c

I see its the Gopedders vs. the Moppeders again, Mods vs. Rockers. One thing that is important, we need to get people riding. With the price of gas, 100 mpg looks pretty good. Peoples natural fear of riding a bicycle, let alone something with a motor on it own is very intimidating. I don't care what ya got, if its got 2 wheels the better. This gas thing is gonna get allot worse before it gets

That is one of the most beautiful pipes I'v seen, its huge! the bike must scream, congratulations, get the speedo fix, courious about the results.

What I can add to this having worked at a metal plating factory, you need 1 to 2 car batteries, the metal has to be sanded rough to brush away any coatings or surface impureties like oils, oxidation, then the metal has to be polished. The thing that costs the most in chroming is the labor of having parts polished. Then you lay down copper, polish, nickle, polish, then chrome, more polishing. Amper

Of course Mopeders own VW's, you can work on them, just like you do on a ped. I got a dead Toyota in the garage, that has a small short that has killed the car. I have been searching for the last 2 weeks to debug the thing. You woulden't find that on a VW or ped. Ive owned a green 64 bug, red 68 bug, white 69 Karman Ghia, blue 70 bug, orange 73 bus, and a silver 80 Sciroco. I have an old

I always ran more oil than I was supposed to, I used to carry a small 6 oz. bottle of oil under my seat to mix at the gas stations. 50 to 1 makes better power, but I was usually around 40 to 1. When you think about it, do you want to run your engine without oil? Less oil will make your main bearing and rings wear out faster. I would take plug readings and would adjust my oil so my plugs would not

I'v done this allot on bikes, take the baffle, get some drill bits, and enlarge the holes on the long pipe. This should increase flow and performance without radically changing your jetting. Right now you may be running lean and on a long trip could burn a hole right through your piston. That would be bad. Running the baffle modified will be a little louder, but not the straight pipe effect y

Call it Quadropheniaholic or what, I have been Mopeding since the late 70's. All my friends in high school bought every second hand basket case we could find and got it out on the road. We would do 100 plus mile trips during the summer, covering Orange County and Long Beach. Mopeds give the flexibility to go out and explore and that is one of the side benefits to having an economical cruiser.

Im just searching the web for gasoline engine Bio Diesel, apparently when bio diesel is heated into a vapor it can result in higher gas mileage. Natural gas and alcohol burns at 8 to 1, gasoline 16 to 1, and diesel 24 to 1. My 77 Peugeot 103 got 100 mpg with a fly cut head, open air cleaner, and full lenth pipe with a dirt bike glass pack. Now there are ways to make bikes that keep at a low rpm on
