Clutch hack on GL 1000 K3.

[Peter T Sweden]

I am renovating a GL 1000 K3 (1979) with uncertain mileage. The engine is running ok but I have a clutch problem. When executing a smooth start will the clutch hack just before it is fully engaged. Is this a sign of rundown clutch or can the problem be fixed without major repair ?.

Hope that someone can help / P Thornström Sweden.

Not sure what you mean by "clutch hack".

Second that, do you mean clutch slip?

Hello again.

In Swedish: Kopplingen slirar inte jämnt ända tills lamellerna är gripit tag i varandra, den hackar på slutet, speciellt om man ger gas.

Try to translate: The clutch does not slide smoothly al the way until it is fully engaged, is goes "hack-hack-hack" in the end if i apply some power.

Your comment that the bike has, "uncertain mileage" would cause me to lean towards replacing the clutch. However, 'first things first'.

First, make sure that your clutch cable is routed and adjusted properly. As you are probably aware, there are two adjustments for your cable, one near the engine and one at the lever. Follow the instructions for clutch cable routing and adjustment in your shop manual. Many clutch issues can be resolved with proper routing, adjustment and cable lubrication.

If this doesn't resolve the problem then, before pulling the clutch for replacement, change your oil. This is a 'must'. GL 'wet' clutches function most effectively when they have fresh, good quality oil that's rated for motorcycles with wet clutches i.e., they contain no friction modifiers. Many owners who've experienced unusual clutch performance issues found that they were using the wrong type of oil or, they'd just purchased a bike which was filled with automotive oil by the PO.

Do you mean clutch judder plates rattling in the clutch basket as your about to pull away

Thank you for your replies.

I will check and adjust the cable and I have bought Motex 4T-X Mc oil for the winter service on my Hondas.

If you do all the adjustments and still find that you have a problem, it could very well be the all-too-common one I wrote about here:
