So like the title says, I am unable to get any power above a 1/3-1/2(?) throttle position, 82 CB450T...I have to short shift and get all the way up to top gear in order to maybe get 42 mph. If I attempt to give more throttle, it just gives a almost bog and slight slowdown. Does this sound more like a carb issue or a valve issue? I believe I had this same issue right before the adjusting nut came off the left intake valve and then seemed to caused the valve to rip out the valve retainer. I bought and installed new valve retainer and reinstalled it all together. I cleaned up the carbon off the valves and head while I was in there. I ended up getting new carb boots and installed the boots to the carb from the airbox properly, since whoever was in it last apparently didn't. I did the valve adjustments according the manual. although it seems to be running smoother, I attribute namely to the carb boots, it still seems to be louder than I would think it should be, but I also haven't done the balancer adjustment. even though I feel/hear like its coming from the top end still? anyone got a video of one that's not got problems and what it suppose to sound or how loud its suppose to sound like?
