Partzilla Live Q&A Highlights – Motorcycle Cooling System/Overheating Problems
I have a 2008 Suzuki GSXR-1000 that spills coolant from the overflow hose coming from the reservoir after a hard ride. Do I have air bubbles?
John Talley: Air bubbles, possibly, but I’m wondering if you’re having a little bit of a flow issue, because it shouldn’t be spitting this out so easily. The GSXR is a performance machine and you should be able to ride it hard without it putting too much overflow into the reservoir … that’s what it’s there for. … So you may have air bubbles, but I would flush out the system and refill it. Make sure it’s clean and your thermostat is up-to-date or has been replaced recently. When it’s over 4-5 years old, it’s probably time to go ahead and pop one in there, and it would be a great time when … doing a flush, to go pop in a new thermostat because they don’t cost that much, and that’s one less thing that could be causing a problem with your machine.
I have a 2016 Yamaha R6. I was at a stop light in first gear and the bike stalled on its own. What do you think this could be? It wasn’t a hot day and the fans were on.
John Talley: When you say “stalled”, are you telling me it just shut off? And it wouldn’t start again? I guess that could be overheating, and that could cause it to shut down. So it’s a ’16, that’s coming up on 4 years old. Maybe it’s time to do a coolant flush on this one. If you would, reference one of our videos. I haven’t done a coolant flush on an R6 but it’s basically the same process as far as draining it out, and running a flushing agent through there a couple of times and then refilling it. It may be time to do so on yours, especially if the fans are working.
I have a 2009 VT750C2 Honda Shadow. I changed the clutch ring set, but I’m getting high temperature in heavy traffic. I feel the clutch is loose and I need to adjust the cable in order to disengage the clutch from the transmission. Is this normal behavior?
John Talley: No, as it heats up, that shouldn’t be an issue. I wonder if you just have it a little too tight from the get-go, and you need a little bit of time to break in a clutch. Give it at least 50-100 miles … Let it get seated in, let the clutch plates wear in. There’s basically a burnishing process, almost like breaking in a new set of brake pads. You’ve got fiber going against metal and there needs to be a little bit of a transference before they really start to engage properly. … don’t hammer it too hard and then reevaluate it but just make sure that you don’t have the clutch too tight from the get-go.
