I recently acquired a clean 07 ZX6R Track Bike from a very meticulous owner. Before winter storage last year he changed the spark plugs, oil, filter, air filter, fresh V-Power and stabilizer.
When I went to buy the bike we were running it in the garage and it wouldn't rev past 10k. It would rev up to 10k then rev down to about 9k and eventually hold around 8k. I tried this a bunch of times and it continued to do this. I still bought the bike and got an even better deal on it now knowing that there was this issue.
After bringing it home I got rid of the old gas and put some fresh V-Power and SeaFoam in it. Still wont Rev past 10k. When running it for a few minutes in the garage I noticed the header and cat were literally almost melting (they were bright orange and almost melting the lower fairing). But the rest of the exhaust was regular temp and not red hot.
After tearing it down a little last night this is what I am finding:
1. Fuel lines not obstructed and connected properly
2. Air lines not obstructed and connected properly
3. All wires and harnesses connected properly, plugs and plug caps connected properly
4. Fuel pump is cycling and working properly
5. Battery is new and fully charged
6. Brand new air filter
7. 4 brand new spark plugs (NGK CR9E) but appear to be running lean (Pics below).
8. Fresh oil and filter
9. No error codes or flashing lights
Does anybody have any ideas what is going on here? Why won't it rev any higher than 10k? The redline is 16k. Why is the header and cat glowing red hot? Is there an obstruction in the cat possibly? Injector issue? Any other ideas? Anybody else experience this before? Do you agree that these plugs show that it is running lean?
Bike is all stock except an Akropovic slip-on.
Any help would be most appreciated.
