I was seeing if anybody has had the same trouble,with the right front exhaust valve keeps coming loose? I've put a new nut and screw adjuster,and it still keeps loosing adjustment,and the nuts still tight. I've looked in the manuel, and they say that if the other 3 are loose,it's the decompresser going bad. I talked to a guy at the honda shop ,he said he never heard of that before. Any help would be greatly appreciate it.
