I'm getting a f1 code of 2 long red flashes and 5 short ones..MY Bike set up a little fre a knee replacement.

my bike has 143,000 miles

I use 90 proof

Recently thing it might be be water in the fuel.
the bike has plenty power and handles great

Should i worry about this f1 code?

A 25 code indicates the right knock sensor but it's more likely to be the ECM. It won't hurt anything except maybe the fuel economy. Never ever put your email address or phone # in a post on an open forum unless you like spam emails and phone calls. We won't email you with a response anyway, they are posted right here.

the bike is designed for 87 Octane, you are wasting money buying 91 octane, and fouling the plugs unnecessarily

my '02 had a bad ECM, it lost a bit in MPG, but ran good otherwise.
if you can't afford a new ECM, just forget it and ride.
