After service and bike still not running correct

[Tmation]

Did it sound like a bag of nails before you serviced it?


I would start with the basics,

• [size=78%]Is the air filter fitted properly and intake to airbox clear? [/size]
  
• [/size][size=78%]Are the plugs fitted correctly and are they the right heat range? [/size]
  
• [/size][size=78%]When you pulled the plug caps of the plugs you may have loosened the HT to plug connection[/size]
  
• [/size]Did you change the fuel filter, is the fuel flowing from the tap etc[size=78%]
  
• [/size]is the choke sticking on[size=78%]
  
• [/size]all your electrical connections are clean and sound (including earths)[size=78%]
  
• [/size]If the bike has stood awhile the carbs might need stripping and cleaning plus seals/gaskets/jets changing
