My question is about the installation of the upgrades , is it self installation ? Does it come with instructions ? Or it requires us to take engines to dealer to spend more money, how much More ? I noticed engines parts are not included in the package so if somebody could explain difference between of a new 2015 engine with all updates including lighter piston & crankshaft and the old engine without new piston & crankshaft ? How much would cost new piston & crankshafts including installation & labor from dealer, which I really think is where all money is at . I noticed engine block is different not only the black / red paint so does it make any difference with old engine? There is a lack of information about this EVO update and my opinion it’s not only the $470.19 (Sr./master)+ delivery Cost + Engine parts + labor That worries me updating my old engine , what if after all Big money spent then This Engine cant Catch up With a 2015 original Engine . What if We just sell old Engines and buy new one With all updates and not half of them without spending moré money On labor & Parts installation . The main concern it’s if it is worthy to update old engine with all this lack of info from Rotax.
