Now there is a lot of debate on this forum that whether to go for Euro 2 or Non Euro 2, or which one is better.
Here are a few misconceptions which exist.
1) Push rod design is changed.
Although the above picture only shows the change of tappet covers the truth is no the pushrods are not changed, the only reason for changing the cover was to adjust crank case emission control system.
As posted by @abobobillythe push rod design was changed in 2003 when they switched from Japanese to local ones
Picture taken by @<a href='https://www.pakwheels.com/forums/user/abobobilly'><span class="bbcode-b">abobobilly</span></a> the thinner being the current ones (my CG2011, and CG2014 has them) and the thicker being old Japanese ones.
Secondly another marketing tactic by Atlas is "NEW ROCKER ARM DESIGN"
Well unfortunately this isn't true as well the picture below is of rocker arm's of CG125 1984 model (Workshop manual)
Spot the differnce cuz i couldn't cuz there isn't any
So people there is no way a Euro 2 is technically more advance that non Euro 2 apart from ofcourse the Emission control system which basically makes it Euro 2 (and was a majburi of Honda). Euro 2's might be better due to being new but one also has to consider the decrease in standards compared to previous years.
So which one is better ? I leave that decision up to you.
