    Emissions problem

    I recently moved from Ohio to Arizona. When the time came to get a license for my GS1100L, it failed the emissions test. Some one said that if I mix the gasoline with a smal amount of another type of fuel it would burn cleaner and cause an effect that will result in passing the carbon test when the emission test is made. Does anyone know of theis trick I can use to get the bike to passed the test without having someone mess with resetting the bike to the standards of Arizona. The bike runs perfect and I am afraid of having someone ruin it. Any input would be appreciated.

    Hi,

    You'd be surprised how much a fresh oil change will affect your emissions. Otherwise you could try to go down a size on the pilot jet, maybe adjust the idle fuel mixture screws a half turn clockwise. I don't know if it would be necessary to go down a size on the main jets or needle jets/jet needles.


    Thank you for your indulgence,

      if he is on stock setting then adjusting the idle screws for max rpm would probably do it.

        If your bike is running a wee bit too rich, I think obtaining four 'extra' screws for the balance ports and drilling a 'very small' hole through the center of each one would lean 'er out just enough to make it pass the test. ride the bike to the testing station, remove the stock screws from the balance ports, replace them with the above mentioned screws and re-install the stock ones before you leave.

        don't go overboard with the drill... small hole is the key.

          I thought once vehicles were beyond a certain age, emissions standards no longer were applicable. I know that was true in Fl the last time I checked (which was many years ago ).

            Arizona has a plethora of emissions laws in their high density population areas. They apparently don't care the age of the vehicle, it's got to pass the standards (maybe a collector plate or historic plate vehicle doesn't, I don't know). They compete with CA to see who can cause the most discomfort in emissions laws as in several other areas. GSBill lives away from the city areas, out in the desert I don't think any emissions testing is required.

              You might also try 1 step hotter spark plug for the test.

                It would help a lot to know what part of the emissions test your bike failed.

                  Unburned Hydrocarbons. Tailpipe emissions. If it's running too rich or too lean for their standards it'll fail. The reason these bikes run so lean from the start is the CA emission standards of the time, but they have never required emissions testing on motorcycles.

                    Hey there....Like Brian said, post the test results and maybe we can help more. Theres a fine balance between hydrocarbons and carbon monoxide....High HC indicates incomplete combustion and high Co indicates a rich condition.....What were the numbers ? And can you scan the test results ?.....Billy

                      Just something to try - If you go to an auto parts store -Pep Boys, AutoZone, Advance Auto Parts, etc - I don't know what's out there in the southwest (I live in North Carolina) they sell chemicals you add to your gas in order to pass emissions tests. I have not tried them - could be snake oil - but it might be worth a try for you.

                        This is what the smog guy I go to said. He's an old timer and we got talking for a while and his words were to never use ARCO gas (don't know if they have that in AZ but it's everywhere in CA) and that through experimentation he's found that almost any car will pass with a mix of a gallon of 100 octane (we have VP) and a gallon of methanol. Methanol (not ethanol like what they make from corn or whatever) can be found from race supply places and I was surprised that it was actually pretty cheap.

                        I luckily didn't have to try it but he said it took him a career of smoggin to find that combo. Use the mix then cruise the freeway a bit then go for it.

                        two cents worth anyway,

                        Good luck,

                            Methanol will lean out the mixture, but there is a fine balance here. If the mix goes to lean the NOX will go high, and still fail. A dirty air filter will make the co go high, so make sure it is clean.

                              Rather than pay the high prices at race stores, buy a yellow bottle of Heet. It is 100% methanol and a lot cheaper than the race stuff. I run it in my TransAm methanol injection system. It has to be the yellow bottle, btw.
