Re: First build on China
Yes you can do damage if you run without the baffle/end cap. 2 stroke engines need the back pressure created by the muffler or expansion chamber. Running without it can cause the engine to run lean and hot. The lean burn is why you feel a little more power but it won't last if you continue to ride it like that.
Not only can you damage the engine but you're not doing the hobby any favors either. You might like the sound but the folks around you won't be impressed. Muffle it with a new muffler or go for the expansion chamber.
