For example, if you move from sea level to a new home in the mountains, you will want to screw the pilot jets in a scosh, because a bike set up for sea level will run rich at 5000 feet вЂ“ the fuel supplied is the same, but the oxygen is less. It should also be noted that pilot screw settings may absolutely need to be changed due to outside circumstances. Also, if your carb was set at the factory last thing Friday afternoon when the country music station (and they have them in Japan) was playing вЂњTake This Job and Shove ItвЂќ, these screws may not, in fact, have been set correctly. However, for those of you who cannot leave well enough alone and are ready to risky heavy fines and imprisonment, these plugs can be removed and the CO settings adjusted a tad richer for quicker warm-up and better low-end performance. Most Viragos run very well on the factory settings, and if yours has good power you should probably leave well enough alone. The reason is that fuel flow rates have been set to EPA standards (on the lean side) at the factory and are not to be changed. Viragos come from the factory these screws are blocked by brass or aluminum plugs so that you canвЂ™t get at them. CO readings are changed by turning the pilot screws in and out. Richness/leanness is typically measured by the percentage of CO (carbon monoxide) present in the exhaust gas вЂ“ more meaning richer, less meaning leaner. The term вЂњrichвЂќ means more fuel to air, and term вЂњleanвЂќ means less fuel to air. Somewhat oversimplifying, there is an вЂњidealвЂќ ratio between fuel and air which results in the best and most powerful burn. First, the richness of the idle and low rpm mixture (controlled by the pilot circuit in the carburetor) can be set. There are three things that can be done with the carbs.

The Clymer or Haynes manuals also cover this.

The factory service manual is the best source of information on how to do this. This procedure is one that the enterprising Virago owner can learn/master if he/she is so inclined. Well, then, how about the valves? As part of a tune-up, the adjustment on the valves should be checked and if found to be out of spec, reset. Most owners should be able to handle the plug-changing chore without too much trouble. In these latter cases, youвЂ™ll want to find out the reason why this occurred. New plugs should be fitted at the called-for intervals or if they become excessively dirty or fouled. Changing the plugs was always part of a tune-up, and it still is. While you do need a strong, correctly timed spark, thereвЂ™s just not much to вЂњtimeвЂќ here. If a problem is identified, youвЂ™re still not adjusting anything вЂ“ youвЂ™re replacing parts or maybe checking connections. While ignition timing and advance can be checked with a strobe light, unless you suspect trouble there is little reason to do this. The ignition advance is controlled electronically by the TCI unit, sometimes called the вЂњignitor boxвЂќ. Rich? Wrong! There are no points on the Virago and the ignition timing is preset, that is, not adjustable.

The first thing we do is what we did with our old cars, change the plugs, install a set of points and then set the time. So the following group of procedures may be thought of as a tune-up. You will note in the recommended maintenance schedules that different procedures have different time intervals. If you changed your plugs 500 miles ago and did it right, you wouldnвЂ™t do it again just because you decided to check your carburetor settings. But, what does вЂњtuningвЂќ the Virago really mean? When you take your bike to the dealer and say вЂњI think it needs a tune-up,вЂќ what specifically should the dealer do? Or, what should you do it you are going to attempt it yourself? Her is my cut at an answer to these questions.Д«efore we get going, we should note that the various elements of a tune-up donвЂ™t necessarily happen all at the same time, and might better be thought of as separate procedures. We hear terms like вЂњmajor tune-upвЂќ and вЂњfull serviceвЂќ. вЂњBikeвЂ™s not running quite as strong as it should. If your bikeвЂ™s running strong and true, just change that oil a lot (and some of the other fluids now and then as well) and enjoy your career as a Virago rider.Д«ut there will always be a few folks who think they need a Yamaha Virago Tuneup, and maybe they do. The thing about a tune-up is, you likely donвЂ™t need one.
