GL 1500 clutch slips

[andyqpayne]

I have a 96 gl 1500 se. When i bought it 50,000 miles on it cutch would slip at high speed. I have replaced clutch plates, cutch line and rebuilt master cylinder and slave cylinder. after riding for about 100 to 150 miles i will have to open bleeder and let air in the line or the clutch will start to slip again. when i open bleeder and let air in line clutch works as it should again.

Check the master cylinder return holes. They are very small and can become plugged. If opening the bleed screw relieves the pressure, the problem is in the hydraulics, not the clutch pack itself.
Also be sure the master piston is returning all the way. I have heard some aftermarket levers need a little adjustment to allow full return.

Yeah, you need to clean out your spooge hole.

it may sound a bit off beat,
but change engine oil over to Rotella T6, 5w40
that is a pure synthetic and No Friction Modifiers.

it helps clean clutch plates of varnish, and the tranny "seems to me" to shift better.
