Re: How to fill oil on front fork 1983 gs650 katana

Thanks a lot. I just got home from vacation. I have taken some pictures and it is just as Blix showes in pictures from cms. The only way to take the spring seat off is to dismantle the hole fork i think. It look like I have to do the work. :oops: I was hoping to drive 1.may. But think i have to dela...

Re: How to fill oil on front fork 1983 gs650 katana

Looks like ES forks with the anti-dive. Under the rubber should be an Allen key socket. 10mm IIRC.

The bike is in Norway.

Re: How to fill oil on front fork 1983 gs650 katana

You have a black rubber top, pop that off, under that is a 19 MM cap , .makes sure you have the adjuster in the middle wound out when putting it back on, it's just easier. As for filling , make sure that you have emptied them both and flushed them , there will be residue of condensation and grime i...

Re: How to fill oil on front fork 1983 gs650 katana

There could be rubber caps on the top. Here's the strip down and rebuild pages from the OEM Suzuki manual. Oil is given as a capacity but is normally fine tuned via the air gap level but as Page 59 says you need to "When adjusting oil level, remove the fork spring and compress the inner tube fully"...
