When i frist crank up my raptor it wont hardly crank. I have to hold the stater button for about a min befor it will ever crank. After it cranks and gets warm it will crank just fine. Thanks

 

Who built the motor? If you are sure the cam decompression mechanism was properly installed, there are a few other things you can do to help:

1) Use a Grizzly battery
2) Run a heavy ground wire from the battery to the starter body
3) Install a manual decompression mechanism
