Well not to stir the pot or anything, but they are kinda small..
I like my warrior, but I'm only 5'6 160lbs.. But their kinda heavy, their under powered, and they don't handle very well. (in stock form)
The 350 is reliable.. But it's very expensive to work on.. I also found that there wasn't much of a performance gain to be had on the popular parts offered.
The motor itself is the heavy part of the quad, that's why I swapped mine out to something cheaper, and easier to work on.
Also their an outdated platform.. Thats why I think most people bash them..
You either love the YFM. Or hate it.
(I like them, their as tuff as nails)
That's my 2 cents.
