well it looks like the 650 is running lean...havent really taken it out yet since adding the snorkel...first trip this weekend...but since installing she has been coughing and sputtering alot when i start her up and she is cold. Anyone recommend a place to get a good solid jet kit at a good price. Help would be appreciated...thanks

 

Try your dealer at $5 bucks a piece get as many as you like.

 

Open the pilot screws out to 3 - 3 1/2 turns and that will reduce the low speed sputtering. The high speed jetting will be lean too, so as Alltoys said, go up one size on the main jets.
