Partzilla Live Q&A Highlights – Suzuki Motorcycle & ATV Repair
Suzuki Motorcycle Repair
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.
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.
Suzuki ATV Repair
I keep tearing the CV boots on the left of a 2012 King Quad. It’s happened three times in the past two years. Any thoughts?
John Talley: It shouldn’t be happening that often. Are you running unusually large tires on it? Because it sounds like they’re getting strained really hard. And if you’ve done any type of lift that will change the angles that they’re operating at, the more you lift them up, the more severe the angles are that you’re going to wear them out. So are you telling me the whole story here? Has the machine been modified, because if it hasn’t, you really shouldn’t be having that many issues with tearing them apart like that.
I have an 02 Suzuki Vinson 500 and the engine won't rev up more than 2000 rpm when it's in gear. I went through the carb, valves and electric and found that the stator wires have continuity between them. What could be the problem?
John Talley: That really just screams like it’s not making the transition from the idle circuit up into the main circuit. I would still go back and look at the carb again. Check your actual fuel level. That’s going to be in your float bowl. You’ve got the jets more or less hanging down in the float bowl and if that float level is too high, it may be getting to the idle or the pilot but it’s not making it up to the main, so check your fuel level to see what’s there. Because it’s easy when you go through those and putting them back together to maybe have bent that tab or maybe it’s not connected to the seat correctly and it’s not letting enough fuel in.
