Throttle rev's but not moving

Postby spragg » Tue Aug 26, 2014 10:01 am



When I turn the throttle on my 93 GL1500 the bike rev's up and barely moves until I back off of the throttle. It does this even when I'm in motion and hit the throttle. I bleed the clutch and still the same thing. Any ideas on what's going on?

So, the bike does motivate itself as you release the clutch?..
But, even if you're already moving, when you open the throttle the bike just putts along?..
This sounds an awful lot like a clutch pack has gone bad. Either the friction discs are worn beyond tolerance, or the springs have weakened. Quite odd for a GL clutch to wear out, have you been towing a heavy trailer??
Keep the rubber side down.

I'm thinking, maybe, plugged fluid return passage in the clutch slave or master?

It sounds like your clutch is slipping. Have you changed the oil recently? Did you happen to use automotive oil in the bike?

It's also possible that your clutch return port is clogged, as mentioned. When did you last flush/bleed your clutch fluid? Try bleeding your clutch. If that fixes it, then chances are it's a blocked port. If that doesn't fix it, then it's probable that you need a new clutch.

If you used a friction fighting oil it will make your clutch slip. You can also run some seafoam in your oil for around a 100 miles at slow speeds dont over do it. This should clean out all the gunk and passage ways,then give her a new oil change too.
