Today I took off the carb from my 06 lc4A and saw something I had never noticed. Apparently there is s division in the middle of the intake to send separate currents od mixture to each admision valve. What bothers me is that the work doesn't seem as an original feature, it much more looks like a DIY version. Here is a picture of what you see when you look in the direction of the valves (valves appear as bright figures with a copper like color):
I also took down the left light, and noticed there is a spot where a bolt might go, but i am not sure if there should actually be something there. The left light actually has a threaded hole that matches the spot I signaled in red in the next picture:
Anyone has any opinions on these issues?
