CBR BOGGING DOWN WONT GET PASSED 45mph
#31
Okay, I'm going to check is the vacuum hose connect to the FPR has fuel in it. That's the sign that is gone bad correct?? I want to say my exhaust does have a strong gas smell to it, which is another indicator right? But that could just be me looking for answers to my problem. I'd have to start it up tonight to be sure.

When you clamp the return line, you're not allowing the excess pressure to bleed off into the tank. The system will be at full pump pressure, which it double what it should be.
Long shot meaning its not a very common thing. Usually the FPR leak and fail... But at this point, you don't want to overlook anything.

Just curious, if I do take the vacuum hose off and it drops or has fuel in it could that also be the problem. I just was looking through other forums and someone (lots of people) stated similar bike issues. Not 100% the same but then again no one is posting on exactly the same issues. I'm just trying to get the bike back healthy. But at the same time a lot of symptoms were the same for fuel pump problems too. So like you said... this is a bitch.

I was about comment again before I read your post. I just changed spark plugs recently. But when I took the old ones out the "pin" was still in great condition at a sharp point. But the end of each plug was brown/black. Which upon doing more research, is another symptom of bad FPR. Once again this could just be wishful thinking because I'm so ready to just know what the problem is! Any thought on this update? I am planning to do some work tonight on the bike. So let me know anything I may need to look into while I'm in there. I am going to try to do the hose clamp after I take the fairings off.

Update: I think I found the problem. Little did I know that there were suppose to be four hose connected to the air box. Well I only recalled disconnecting three when doing previous work. So I opened her up real quick and discovered that the previous owner had broke off the plastic connector piece for vacuum hose #4. So this entire time that hose has been disconnected and not holding the vacuum. I ordered a new air housing so that is on its way. I think this is the solution to my problem! But I will let everyone know after I install the new part and get on the road again.
