Got a 07 zx6r and a 06 zx10r that developed the same problem this weekend at roebling and caused me to miss all races! They seem like they aren't running on all cylinders, just bog down and won't pull. Sitting there revving them, they are sucking air and just bog.
Background:
Ran barber 2 weeks ago, ran both bikes with VP U4.4. Ran great. It was raining at the end so I packed up and went home without draining the tanks...I know stupid. But several seem to think that a couple weeks shouldn't be bad. So bikes sat in trailer till this weekend. Headed to roebling, picked up some 93 octane pump gas to mix in for practice and the solo. Took the 600 out ran like crap. Wouldn't pull and couldn't get it past 4th and 100mph on the straight. Took power commander and ignition module off and still same problem so it's not that. Pulled the plugs and all are firing. It's runs like it on 2 cyclinders.
Gave up on the 600 and decided to run the 1000. Without considering it would be the gas (either vp or pump), I siphoned the 600 fuel into the 1000 on top of the vp that was already in there. It ran fine for one practice session. Went out in the 2nd session and at lap 3 or 4, it started doing the same thing! It runs ok when you first crank it and then it goes south. Plus the fuel light comes on yet there is plenty of fuel in it! Fuel pump maybe? When I pull the hose off the pump, it still dribbles fuel out where the 600 doesn't allow any fuel out of the pump unless the bike is on.
So either the 4.4 doesn't sit in a bike as well as the 4.2 did last year, or I got horrible pump gas. Either way, what all do I go through to clean, check out, replace, etc? I've searched and saw mostly things on carbs, not much for fuel injection bikes. Please help... and keep the flames to a minimum, just trying to get things straight for this weekend at tally!!!
Note, it was 102 degrees in the shade at roebling if that makes a difference and the bikes have been in the trailer in Atlanta....
