2003 K1000 Fuel Delivery?
I got a 2003 Z1000 about a year ago with 2,500 miles on it. In the past year I put about 7,000 miles on it with little problem.
But recently is started to hesitate at highway speeds, feeling like it was running out of gas. I can't guarantee it, but it seems like when I filled the tank up, or possibly just opened the tank, that the situation would improve.
I took it to a shop, explained the issue, and they told me they couldn't find anything wrong with it. They did say they drained the tank and cleaned the lines, and recommended gum-out.
Riding home from the shop, I hot about 50MPH and it started to happen again. This time it seemed like any time I went above about 5500RPM it would happen. I pulled over once, opened and closed the tank, and just revved the engine to about 8000RPM, and in a few seconds it started to sputter and dropped down to about 2000RPM on it's own (throttle was still at same position that had been 8,000RPM).
I don't really want to go back to the shop and might try to go it on my own. Any advice on where to start?
