Suzuki Motorcycle Clutch Issues
When your Suzuki motorycle is about to hit 20 years old, is it time to replace the clutch? Maybe not the entire clutch, but you might want to inspect the clutch plates if they've never been replaced.
Partzilla's powersports pro John Talley goes live on our YouTube channel every Friday at 3pm Eastern. In this edition of Live Q&A, John answers a couple of questions about clutch repairs for Suzuki motorcycles.
Suzuki GSXR Clutch
I have a problem on my GSXR 750. I changed the clutch when I pressed the lever in and switched it first and let it go and it doesn’t start to roll. What can be wrong?
John Talley: Alright, I know that on the GSXR-1000 there are different plates that you have to measure in order to get the correct stack height. And I wonder if you’re missing a clutch plate. Possibly. It sounds like that stack height is not correct and you’re disengaging it and it’s just freewheeling because those plates aren’t touching it yet or not touching each other in between the fiber and the metal disc inside of what I call a clutch pack. Now I don’t remember the exact distance but I’m sure you can find it online or in your service manual. You actually need to measure that to make sure it’s at the right height, otherwise you’re going to run into the problem you’re describing. Also, count your plates one more time and make sure you’re not missing one.

Suzuki DRZ Clutch
I have a 2002 DRZ 400S. The clutch feels fine, but it's almost 20 years old. Should I replace it preventatively?
John Talley: That’s a bit of a loaded question, because those fiber plates do break down after a while. If I were going to take it out for a really serious hard ride, I would probably go ahead and do that, just to get that out of my mind where that wouldn’t be a potential failure. Because when those plates get older, when they do finally start to break down, they dump into your oil and guess what? That gets circulated throughout your whole engine and can cause lubrication problems. Especially if it starts to stop up some of the old passageways. On the DRZ, that’s not such a huge problem, but I’ve seen it on sport bikes when they start to break down, it usually has a catastrophic effect.
