May be a bad coil. It will only fail when hot.

SOURCE: missing, back firing just working really bad!

im not certain as i dont have a maintanance manual for that bike, but intake valve clearance should be approx .004 and exhaust valves should be appxox .008 also you may consider taking the coils to a shop and have them tested. coils after warming up will begin to fail once they start to go bad. spark will be great when the bike is cold, but once it warms up, spark begins to fade and hit and miss.. this may be the problem. hope this helps.

SOURCE: starts and stays running with choke on. stalls

Pay special attention to the parts in red. DO NOT mix parts from the front carb with parts from the back carb. When removing adjuster screws and jets, count the number of turns to remove them, write it down, and replace with the same number of turns.

Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part, the part is not in stock. www.babbittsonline.com/pages/parts/viewbybrandand/parts.aspx

Go to this site and you can download a free PDF service manual.
www.carlsalter.com/motorcycle-manuals.asp Most all of the manuals are in English but some are not. There is no way to be sure without doing the download. You can always delete it if in a foreign language.

SOURCE: Yamaha TW 200 starts but won't run.

If the bike has sat for a long period of time without being run - the gas that is sitting in the carb(s) will shellac.. Then the carb(s) would need to be cleaned and "rebuilt"..

SOURCE: 2001 yamaha ttr 250, starts, idles ok, bogs at acceleration

Has the bike been stored for any long length of time?
old fuel in the carburetor will turn to a varnish like residue blocking the jets,or possibly water in the carburetor.

Testimonial: "The bike was not stored and was ridden regularly, but it still sounds like it could be the carburetor. Thanks for your insight."

02 Yamaha xvs 650 dragstar classic that misfires when it warms up


First I would change all the spark plugs, and if that didn't make a difference then it sounds like the coil(s) are warming up and breaking down........when it starts to skip take a good pair of pliers with good rubber on them and pull each spark plug wire, when you get to the one that the running doesn't change then I would replace that particular coil
