I have a 2003 polaris 700 with spun motor bearing crank all are done.
I am trying to find out an idea if a sportsman 800 efi motor and add a big bore kit to the new motor with a 700 head and run the stock 700 carb on it.
Or change some wiring to make it a full efi motor and also would it be possible to to take the 800 motor from carb to the efi. I am looking at buying a new fully furnished crank+crankcase just need to know whether to order it in 800 or 700 and where to go with it.
Thanks for your help and input and let me know if their is any members that may can help me with this project with imput.
Also what about head porting and a 800 header pipe???
