Does the weather affect the way my 1987 honda elite runs???
i know it probably sounds dumb but it just seems like in rainy or very humid weather is when it bogs the most, i havnt had a chance to check my belt, ill have to wait til daylight. is it possible rainy weather is causing my belt to slip? im going to break it down a bit tomorrow and hope i can just get it back together and it starts, i even have a variator plate that ive been too nervous to install but i guess if im tearing it down i might as well try, also will changing the variator require changing my jets??? cause the different derestricted exhaust made my moped smoke so i replaced the stock. but wondering what jets would i want to put in it to get it to stop smoking with the faster exhaust?

Re: Probably a dumb question
Variator has nothing to do with the carb or jets. Change the plate, everyone does and it will make you faster.

Re: Probably a dumb question
The answer to your first question is, yes. Atmospheric (temperature, humidity and altitude) changes effect how much power the engine makes.

Re: Probably a dumb question
Greetings:
As The Bear said, and to add:
You think you're "Burning" gasoline, but all Combustion (Including "Internal"...) relies on the Oxygen in the air to provide the other half of that exothermic chemical process. As it happens, Oxygen is only about 20 percent of the content of whatcha call "Air". If the Air is cold, it will be more dense, and therefore contain a few more molecules of O2 than warm air. If the air is humid, it'll contain a few molecules less than dry air.
All this matters because Hydrocarbons (fuel) and Oxygen have a Perfect ratio at which the maximum amount of heat is generated from the combustion process your spark plug initiates. If there's too much fuel, the mixture burns cooler and less force is generated to push that piston crown down the barrel. If there's too much Oxygen, the combustion generates more heat but the process is abrupt, violent and in extreme cases premature. Aside from producing a potentially destructive event, the power generated is weakened by the possibility of a "missed" ignition.
Flash and several other 2-stroke machines I've owned run their best on a cool, high-pressue, dry day, such as after the passage of a winter cold front here in Deepinnaharta. That's because it's jetted (deliberately - for engine life considerations...) pretty rich. The "right" jet for your application can only be determined by your equipment - pipe, compression ratio, carb, intake filter and so on. Trial-and-error should keep to the "too rich" side, because a sortie toward "too lean" can quickly disable the engine and end all experimentation.

Re: Probably a dumb question
What? I thought it was only me? My moped acts a bit differently when it's raining and when it's cooler. =p
j/k. (on the only me part)
Recommend that you change the variator, it's a simple mod that can be done pretty easily (with the right tools).
Is the faster exhaust, new? If it is a used exhaust, they will sometimes smoke because of leftover residue from the previous owner.
Downloading the manual (if you haven't already) will help you get familiar with your moped/scooter and so that you'll not be (or perhaps be less) nervous when working on your moped/scooter.
If you do change out your exhaust, you may be running a bit lean. Learn to take a (spark) plug chop to see how your engine is running (lean or rich, or just right?).

In other words, make sure you jet towards "too rich" because "too lean" will sometimes destroy your engine.Wheelman-111 wrote:Trial-and-error should keep to the "too rich" side, because a sortie toward "too lean" can quickly disable the engine and end all experimentation.

It is a used exhaust, am going to be changing all this stuff at once, the exhaust, the variator, and im gonna try to do some of the mods involving a dremel tool. and now that i know i have a bad belt im changing that too, do different brand belts or types increase performance or are they all just about the same?
