Hi guys. I am wanting to buy a yz2 and maybe a yz4. But I was just wondering if these yz's are made specifically for carpet tracks and high traction clay or if they also do good on low to med bite clay. I also would want to run it on my outdoor dirt track in summer. And what is this ymax conversion? Is it a bunch of parts you buy individually or is there a kit that comes with everything needed and what is the conversion for? And how much does the conversion cost? Any advice is appreciated. Thanks
