    I was planning on doing the zip tie mod, rather with a wire though. I wasn’t sure the benefits of this mod, only that it prevents a little bog. My yfz has little to no issues with bog. Is there any other benefits to this mod and should I even do it? Thank you !

    I have a 2013 YFZ450 and I’m trying out riding tracks. I need a new chain and sprockets but I don’t know what tooth count works best on tracks. Stock is 14front and 38rear. Anyone have suggestions for what I should get that works best on tracks?
