Just bought a 1992 GSX 1100 G and I took it for a short ride. About 20 miles later my clutch lever was not able to effectively disengage the clutch. I believe air got into my clutch hose. I tried to bleed the clutch hose using the bleeder valve down near the engine but it doesn´t seem to work out too well. Is there a special way or tool to bleed the clutch hose? I don´t have an owners manual. Thank you in advance for your help.
