I have an 03 440 snopro that I bought last April. I haven't had a chance to ride it and I can' wait! I do have a bunch of questions about the sled and was hoping someone can help me out. I will be trail riding and I want to make sure it is set up right.

What should the main jets be? Needle jets and slide?
What color springs should it have in the clutches?
How do you tell if the heads are high or low compression?
What kid of studs should I put in the track?
And I would like to add oil injection. can anyone help with the parts I need?
If anyone has any word of advise on the sled that would be great help!

The guy I bought it from said he added the rear cooler, remaped the ecu and he said he never changed the heads, he said you don't need too??

Thanks for any and all your help!
