I want to put a 600-700 ves motor in a 2003 or 2004 polaris pro-xr. I was wondering how hard it is to fit it in and put oil injection or do what ever you have to do.

Thanx

well I put a 600 ves in my 03 440 chassie and it wasnt hard to bolt in but getting the carbs to fit is a pain. as far as oil injection goes use the pump you get with the motor for a tank I used one off of a 78 yamaha ET250 and mounted it over the brake/chaincase. if you have any more questions feel free to ask.

Thanx for the answers but somebody told me that putting the pipe in is a pain do u have to change the motor mount plates at all

for a 600 just use the 440 plates and for a 700 buy some prox 700 plates. for the pipe getting a prox pipe is the easiest but i got a xcsp one to work for this season.
