Sluggish off the line.

Postby japarker » Mon May 18, 2015 11:07 am



Hey fellas. I'm new to the forum. I've have my 79 GL1000 for about 6 months now. The entire time i've had it, it's sluggish off the line and then i feel a bit of a kick (at about 15mph or around 3000rpm). If I'm really easy off the line and pull the clutch a bit when its about to happen, it smooths it out a bit, but it's still there. Flying off the line is pretty much a no go. Someone suggested it could be a timing belt with some bad teeth or possibly clutch plates.

Any thoughts?

Does it have the original points or new electronic ignition.?
Great performance is directly related to ignition timing,great spark,valve timing,valve lash settings,compression and really good carbs including a proper sync.
When all is exactly right,the 1000 will either seperate your arms at the shoulder or raise the front wheel.

I rebuilt and synchronized the carbs and adjusted the valves. Overall it sounds and runs better, but this particular issue is still there. I'll be honest, I'm fairly new to the art of motorcycle mechanics and the electrical side is still a little over my head. As far as I can tell everything is original. Because of the "kick" I assumed it was something mechanical, but if that sounds like it could be the points I'll look into testing them.

It takes a lot of fuel for this,with a mirror in the plenum box,snap the throttle and verify each slide bounces up and down.
Points.Search "split the difference" method for setting them.They must be right on the mark and have the same dwell angle including a functional mechanical advance.

Sounds like the sliders to me. They need to move like hot butter, not just move.
