Suzuki gs550 katana 1982 oil presure

[Guest]

Hi all

i hoping you can help me .
every time I brake very hard the oil pressure light comes on on the bike .if I give it a bit of revs it goes away again . It never used to do this . It says in the Haynes manual that their is somewhere that I can can attach an oil pressure gauge to test the pressure but for the life of me I cannot find it . Any ideas as to the location of it or why the
night keeps coming on

Many thanks in advance

Pull your oil pan and clean the oil pick up screen.

The oil pressure port should be on the right side of the motor, above and behind the ignition cover. It's a large bolt
