I'm the original owner with 21,570 miles on it. It was running fine, one day, bam! this issue pops up. and now, I have people tell me to hold the throttle wide open, and as if it was on queue, now the I can't even move the throttle a little bit. Almost feels as it if it had a lock to it. I mean, can't even move it at all.! This is starting to feel as a curse of some sort.......geez! I can't even try the tips offered here now......WTF
A couple of things...
The throttle being "stuck" has nothing to do with the other problem. Mechanical but might require taking stuff apart to see if something is jammed or cable broken etc. Airbox might have to come off to get to the throttle bodies or it might just be at the grip...? You won't know until you get into it.
Sometimes a sound recording picks up stuff that you don't generally hear "in person". I can't really tell what is going on here. At first, I was thinking it was flooded in combination with a weak battery. In that case, fully charging the battery (and/or a jump) in combination with WOT would be the appropriate solution. (Seems most likely)
BUT...
As I mentioned (as others have as well), there is some sort of mechanical "THUMP" noise that doesn't seem entirely normal. Might not be anything, however there is a possibility that the cam chain has skipped a couple of teeth. This would be a BAD thing and needs to be checked out. Some Gen I and early Gen II bikes had an issue with the cam chain tensioner not always engaging properly which enabled the cam chain to skip and basically wreck the motor because pistons and valves tried to occupy the same space. If your 2007 still has the original CCT (cam chain tensioner), you can't ignore the possibility. Common symptom of a CCT that is not working properly is a "can of marbles" rattling sound from the right hand side of the engine when starting the bike. (May happen for some weeks before actual failure.) Noise goes away after it is warmed up a bit. Unfortunately, you might not have that warning...
At this point, I would lift the tank and pull the sparkplugs. I would remove the oil pump cover which hides the lower crank and cam chain and have a look inside. I would CAREFULLY rotate the engine using a socket wrench on the crank bolt and see if you run into excessive resistance at any point. Unfortunately, if it is severely out of time, the damage may have been done already. If you don't encounter anything, it may be safe to reassemble and try the WOT with a freshly charged good battery... (after dealing with the throttle linkage issue)
Note: With the sparkplugs out, examination of the tops of the pistons using a borescope might tell you if bad stuff has happened. If there is debris in the cylinders or the piston tops have been marked by the valves, it is likely already too late...
Next would be to drain coolant, remove coolant pipe and cam cover and check cam timing using the marks on the cam gears. If you aren't sure about what to do, STOP and get some assistance. Your bike is close to needing a valve clearance check anyway and this might be a good time to do that. In any case, if the CCT is the original, I would definitely replace it!
How comfortable are you with this stuff? Do you know anyone (or a dealer) that you trust for mechanical diagnosis and repair? Where are you located? I would definitely recommend getting an experienced set of eyes (and ears) on your problems.
Good luck!
