Hey guys, I bought a 426 last month and love it. But the prob I have is I have not kept up with th MX scene for the last 17 yrs or so. The 4's have come a long way since I last rode. My ? is what size sprocket should I have on the rear. I will be do trail riding and some street to work maybe. I got plated for st. The last guy who owned it had the wr stator installed so he could run lights. AZ is easy to plates for OHV. Right now it has a 45t on the rear and yesterday I got to open her up but just did'nt seem all that fast. RPM's were high when I was hauling down the dirt road. Can you guys give me ant maint tips, riding tips, and any general tips? Thanks!
