Hi Everyone, I'm hoping to be selling my '01 MXZ 600 soon so I can get something newer. Based on my budget it will be in the '04-'06 range. I plan to stick w/MXZ. I'm excited to upgrade, but my '01 engine has been trouble free with over 7500 miles. Never had to open the motor. It seems the newer machines are much more troublesome and harder to work on? SDI is fuel injected vs non has carbs, right? I'd be curious to hear thoughts/suggestions on year and type to look for. I saw a '05 MXZ 600 with 2100 miles (no SDI) for about $3800 which sounds pretty good. Are there years to stay away from? Thanks in advance!
