Hi everyone and thanks for adding me. I upgraded from an 8n to a 190xt and am trying to work the bugs out. I'm wondering if you guys can help me out. I have a valve assembly leaking that I need advice on rebuilding it or replacing it. Where is the best place to get front tires? Any feedback on the 190xt's? I paid 4000 for it and it runs like a dream. The loader works good but slow. Everything else seems to be mechanically sound besides the steady drip from the valve body. Here's pics.
