High pitched noise in fuel tank
#18
Your fuel filter/regulator is blocked and needs replacing.

What is happening to your bike(s) now is, the internal parts of the fuel pump are working harder to get fuel through the blocked filter causing them to wear prematurely and break apart on a microscopic level. This is putting high traces of metal particles (mostly copper and zinc) through your fuel system, reacting with the petrol and degrading it. Soon you will have a loss of power and struggle to get past aprox 7000rpm. It only took mine 2 weeks to get to that point from the moment I heard the whining noise......but I ride about 800k's per week, so it happened quickly.

I've now had multiple GenII fuel pumps and filters lab tested. All tests came back showing the same results as mentioned above, and I also posted the data from one lab test in another thread.

Keep your eyes on Ebay for a second hand low k's assembly and change them over yourself as it's a simple job.
I got mine for $160 complete (pump/filter/float etc....). Brand new will cost you around $800 for parts alone. No matter what....it needs to be done.
