I have a 2006 Viper 90r (sons) and would like to know about cold weather running. I live in Michigan and cold weather is finally upon us. Does anyone have experience running this machine in the cold. I am concerned with it not running too lean. Carb adjustments? Should I use premix for winter? Its oil injected and I run Amsoil synthetic in it. Could there be issues with proper oil flow due to the cold? Any comments or suggestion are appreciated!

 

The only thing that I can tell you is we raced up in northern WI the first weekend in May. It was about 36 degrees. I didn't change any jetting and it ran fine. I did put just a little oil in the gas just to make sure but I don't think that I would of needed to.

 

They run rich enough from the factory it's not a problem at all.
