Carbs gummed up. Need a serious cleaning or a full ruubers replacement/rebuild kit. Gas turns to gummy when left stting in the fuel bowls.
Use a couple of cans of Sea Foam.. best stuff in the world.

If you have used Dyno jet kit I have had a kit come through with smaller main jets than the stock ones causing it to run way to lean.
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.

When removing the pilot jet screw, count the number of turns to remove. Put the screw back the same number of turns then unscrew 1/4 turn.
