I am thinking of buying a cheap 2008 KFX450 with a rough idle. I'm looking to spend no more than $500 dollars in parts to get it running right and I know some of the fuel injected machines can get pricey to fix depending on the parts needed. Since the quad starts and runs with just a rough idle I am thinking it is a minor problem. What do you owners of these machines think? I appreciate any feedback. Thanks!
