High pitched noise in fuel tank

[storm]

guys one thing about doing this.....it is just a temporary bandaid fix that has potential to lead to other problems later.

Can't vouch for Gen1 but you will never effectively clean out the filter on the GenII - it's simply not possible.
Inside the sealed canister is a heavy duty V-folded filter element about 3/4" thick....designed to trap particles and be thrown away when clogged!

A quick experiment of a similar process would be to take a filter element, pour used sump oil through it for 1 week..... then try to reverse flush it clean.
Yes you will be able to flush the bulk away but once the particles trap in the element....it's garbage....you will never clean it!

Doing the reverse flush process using chemicals will break down some of the sediment in the filter and if that starts to pass back through
the filter when running again..... that's headed straight to your injectors. Also you still have a constant increased load on your pump which does wear the internals
faster leading to other problems later from the metal particles reacting with the fuel - lab test results have proven that already.

You need the fuel to detonate and burn as clean as possible for best performance, and by choice ya'll are starting by running it through dirty old filters!

IMO this isn't a process to save money, as it has direct potential to cause problems later on in the engines life which would outweigh the savings of the temp fix.

Your bikes, your choice.... but please have a think about the pro's and cons of doing this.

so whats the permanent fix? new filter?
why is this not happening to other bikes like the gixxer or the bmw or cars as they use the same fuel?

cheers

1 drain fuel from tank
2 remove seat

4 lower tank unbolt n remove tank from bike,only undo the 2x 12mill bolts to the frame ,leave the 4x 10 mil bolts alone
5 place tank on soft surface upside down ,getallen key undo bolts holding in fuel pump
6 lift sender pump assembly from tank being careful not to bend fuel float
7 remove fitler from pump assembly 8 spray with carby cleaner ,then use compressed air the blow backwards back flush etc while doing this wrap white cloth around fitler as shit will go everywere
8 follow steps in reverse to re-assemble
good luck

Thanks grant.that's great instructions.
