Looking at making the move from 2 stroke to turbo nytro and need some advise from you all because i literally know very little about yamaha but i know the engines are great. little better than my dragon 800 i suppose. I have came across a pretty sweet deal on a 2010 nytro push turbo 163 or 162 track what ever it is with really low miles (about 300). Is there anything i should be aware of with this particular year or any questions i should be asking with this sled? I should have asked these questions before i bought the dragon and 2 new engines later i am regreting it. Any good word or words of advise would be appreciated. It is the 180 Kit or whatever they refer it as. Thanks for the input.
