Is that a range for all the valves or for the intake and exhaust? Some engines have the same across intake and exhaust but many have wider gaps for the exhaust side. That is what my first thought was. Did you check them and record what they were at before changing them? They would open up and never close up right so the initial gap would be something to consider against the 0.04-0.06mm, in as did it make sense.


I am fairly certain that Minsk has that engine in one of its bikes, maybe they can offer some insight?
