I bought a 400ex with a blown engine, it was a 440 12.5:1 with ported head and stage 3 camshaft. the timing chain broke and caused all the damage. I bought a good used stock head and an 11:1 piston kit and I'm wondering if I should re-use the cam I have or replace it with a stage 1 or 2 cam?
The head that came with the atv is not repairable or I would have rebuilt it.
I just want the quad to putt around on and don't need the high output mods but it was cheaper to buy a 440 replacement piston kit with gaskets than it was to buy a stock cylinder and piston kit.
