Slight Grinding When Switching Gears

Postby SAILOR » Tue Apr 16, 2013 8:26 am



I'm having a little grinding when switching between 1st and 2nd gear, and sometimes it ends up in neutral instead of second gear. Also a slight grind between 2nd and third. Never seems to grind between 3rd and 4th, or 4th and 5th. The clutch also seems to engage and disengage when the clutch lever is about all the way out. Was wondering if there is any adjusting I can do? Or is it time for a clutch job? Bike has almost 30,000 miles. If it is time to do a clutch how much work and expense might that be?

A couple of notes...
The clutch grab point seems too far....Verify if it's the clutch or hydraulic problem by cracking open the bleeder to relieve any pressure in the line...just in case the pressure relief hole in the master cylinder is plugged.Then try the clutch again.
Mine starts grabbing around half stroke.
Second...the trans are not syncromesh like cars..it's just slam it in gear.Grinding is not normal and is usually associated with slow shifting habits or a clutch that is not releasing well.
The wings do sound "clunky" a bit.Sounds like my old ford and built that way.
I've had many wings over the past 25 years and not one has needed a clutch replaced.

What RPMs are you shifting at

Usually 3500-5000 rpm for the 1100-1200 and 2500-4000 on the 1500
Normal driving.Near red line if needed.

I found 4000 to about the best for mine, plus little firmer shifting. Changing to Sell LE oil made the biggest difference.

Yes indeed.....Every bike is just a little different in how they react...It's a learning curve when it comes to each used machine.
Even with the exact same year and model,a mistreated bike operated different than a babied one.

Seems like if I shift at higher RPM's the grinding is minimal or non-existance. I've found if I hardly let off on gas and then shift it goes in fairly smooth, but I still have to kick the shift pedel with a lot of toe pressure. The GL1500 i just sold was a much smoother shifting machine. Where might I find the clutch bleeder value. Also what procedures should I use to crack off on it, plus what difference should I see by letting out some pressure?

Ah...that's the idea.crack the valve and you should see very little fluid come out as there should be almost no pressure on the clutch line till you pull the lever.
My 84 bleeder was on the battery side.In front of the battery,mounted to the rear of the engine.
operate the clutch several times and then crack the bleeder open.A few drops are normal.If you get a squirt,the bleeder hole in the clutch cylinder is plugged.
My thought comes from what you said about the clutch operating at near the end of the lever. It could be it's not fully releasing the clutch.
