Hi again! I have 2 questions on some of the uncorking stuff. 1) How hard is taking off the smog stuff? The reason I am asking is because in N.Y. we have our vehicles hooked up a computer to check for pollution control. I'm not sure that they can do it for motorcycles yet but I may have to put it back on to pass inspection at some point. I have been in Taiwan since all that started so I have no idea how they do it. My second question is what does it do for gas milage? I have read were guys are getting 120 miles on a 4.3 gallon tank. I can do that with my stock tank. I think they maybe R's though.
