Hey guys! Just took the CX500 out for a ride today and noticed that when I really got into it accelerating up a hill, the engine would pull fine until around 5500rpm and then it would bog down. Almost like it had a rev limiter. The bike runs great and has tons of power up until that point. I think the carburetors must just need to be richened up a little on the high end. Now I know that these carburetors have to be in sync with each other. How do I make sure of that? Do I use a vacuum tester or just make sure the same screws on both carburetors are equal turns out? My other thought is that the carburetors might not need adjustment, but that because someone ported the pipes on my bike (it's obviously louder than stock) that the jets need to be drilled out or replaced with a bigger set. Could this also be an issue with the air filter and not enough air getting into the carburetors? Do any of you run the small pod filters on your carbs instead of the stock air box? Give me you feedback and advice!
