So i have a 2011 EFI 700. the SxS will crank right up everytime without any issues. If i let it run or ride it for about 10 mins it will shut off and then it may turn on if i am lucky but most time i have to let it sit for like 3 hours and then it will run again. i have done the following
-New fuel filter
-New injector
-New spark plug
-New coil pack and plug wire
-New air filter
Also could i get a grizzly 660 engine and put in it or would it not work.
