I have a 06 Grizzly 660SE. I love the machine but when it sits in the cold it has to crank the motor for a really long time before it fires. Then when it does fire you have to let it idle for awhile or it quits and sputters right away. Is it really that cold blooded or is there anything i can to to help?

 

My friends 660 is like that, it,s a tricky choke just move it a hair over and it will mean the difference of a difficult cold start up or not.

 

Sounds like you're valves are a lil tight... (had this exact problem on my 02 griz 660.) After the adjustment it started much easier...
