GSF1200S Oil-Cooled Maintenance

Well now
 

 
This filter can cause trouble ★
With a rusty tank, rust gets clogged up here and “after running a certain distance the engine stalls and stops!!”
“About five minutes later it starts and runs, but then the engine stops again!”
In city riding it’s fine, but when you open it up there’s this “boooooo” sound.
 

 
I really love this BST carburettor—it’s used on the GS1000S too ★
