You're assuming it's the fuel pump. You need to do some troubleshooting instead of just throwing parts at it. Fuel pumps don't usually have a problem only some of the time. They work or they don't.
It is very intermittent. Haven't been able to get it to act up during testing.
Between the years 2012 and 2018 The bike was sitting in a garage and only got a total of 380 miles. During the next 2100, this has been an intermittent issue that has been getting worse.
Talked to local shops and Fuel Pump has been considered the most likely.
Not having any other issues with the bike.
Gas tank has been flushed, fuel treatments have been used. I was thinking I got bad gas several time until I finally noticed the pattern that every time it has been between 90 and 100 degrees.
if I get fresh gas and the tank is cold from the gas coming form ground tanks it runs prefect all evening, but then again I can feel the cold of the tank.
Cool days, I can run 10, 20, 50, 100 miles no issue.
Day gets hot, tank hot, I might run 1 , 2, 5, 10 miles. no way to guess when it will put me on the side of the road. But it straightens up every time i restart it..
(yes, I did make sure it got it 600 mile service, oil, valves, etc.)
Fuel pump is the first part I have found confident enough to consider replacing after talking with people and reading symptoms on the internet.
Yes, it is fuel injected.
