My Yamaha CS5 is currently having some tuning issues right now. The bike runs great at idle and up till about 4500-5000 RPMS where it takes a crap, it loses ALL acceleration and power and even refuses to rev above 6k. We've screwed with the timing, cleaned the points, and so far, all we've accomplished is making the bike run better in the 1-4.5k range. Any ideas on what is wrong with it? We are starting to look at the carburetors, but I don't know if carbs will make the power stop so quickly, it's like hitting a wall. Any help appreciated, thanks!

Carbs were SUPPOSED to be cleaned last season, and I replaced the fuel lines while I was cleaning the petcock and gas tank. We're going to work with the carbs on Sunday when my dad and I both have some free time, thanks!
