Whirr when leaning

Postby TJ-GL1500 » Tue Feb 02, 2016 8:35 am



Hey guys!

I'm fairly new to the Goldwing, and I've only had my 1500 for a short time; so this may be a total n00b question.

I noticed a while ago that i'm getting a whirr from my wheel assemblies when coasting. It gets much louder when I lean it more than a few degrees. Bike still stops fine, and brakes evenly. Tire pressure is good, as is the rear suspension pressure.

Is this normal?

If not, any ideas?

Your tires are cupped causing the whirring sound. Most likely the rear tire is the culprit.

Dunlops are famous for this but other tires do the same

On my 1500, with my first set of Avons, it was the front that cupped. I wasn't running the pressure high enough (very common cause of cupping). I now run them at 41 front/47 rear (cold) and no more cupping.

But yes, what you describe is classic tire cupping.

Thanks, guys. I'll up them to 41/47 as per suggestion.

I'm used to my old harley. Never heard any whirrs or rattles or felt any non-motor vibrations on that thing.

depending on what tyres you have fitted you can only go to manufactures highest rating most are 41 max for back tyre

I just ran down to the garage and checked em. I was already at 2-3 above manufacturer suggested on both front and rear.

I was running Metzlers on mine and at 41-41 both tyres cupped it is just one of those things with the heavy wing my mechanic did say that the tread pattern has alot to do with it as well as the cupping on my tyres was consistent with the tread pattern Was a bugger too as rear still had plenty of tread left but vibration was so bad when cornering

Since you just got the bike, it may be that they were already scalloped from the previous owner running too low a pressure. When I got mine, it had very new tires with no scalloping, but I also ran a rather low pressure. They developed a pretty good case of scallops, and were very noisy, front and rear. I upped the pressure to 41 front and rear, and over time, the scalloping wore down to barely noticeable. Mine are Dunlop K177 OEM tires. I've actually gotten great mileage from them, 15K miles on the front, and still running it. The rear got a nail at about 12K miles and I replaced it, but it had plenty of tread left at that time. You might keep the pressure up, and see if it doesn't correct itself over time. My rear had gotten so bad, I could feel it in the seat and footpegs when slowing down. Braking made it worse. But, like I said, it did correct itself.

The tires still have a ton of tread left. I'll keep it high and see what happens.

Since the cupping has already developed increasing the pressure won't change the whirring much when in a lean. The damage is already done.

What brand and model of tires do you have installed? Do what you want, but I would not recommend running the tire pressure any higher than the tire manufacturers recommended maximum pressure cold... Those numbers are there for a reason... If some day you run a TPMS system you can see how much the pressure increases as the tire gets hot.... It will surprise you......

As for what tires (tyres?) to use, there are several posts already debating everyone's choice and reasons. I'm sure our fearless leader can direct you to those! Or try a search for "What tires to use?" and see where you end up, you might find answers to questions you don't even have yet! This is an incredible web site!

Don't rule out bearings drying out and the wear on the brake pads. Both can cause the same sounds when leaning over.

My rear tire whirss a little too when leaned over. Maybe I'm just not running enough air in it. My old dunlops were noisy and cupped. Really gave the poor bike wobbles. :D

Since I installed the Blackwing brace I have no more cupping even with the Dunlap tires. I do get a little rumbling in turns but nothing out of the ordinary

I have a 2010 Wing running my second set of Bridgestone's. The first set which came with the bike when it was new did develop cupping only on the front from about 18,000 km. I increased the pressures from 36 on the front to 41 and left the rear at 41psi. The cupping did improve a little but was still there when I replaced them at 30,000 km. Just after I put the second set of Bridgestone's on I also fitted Centramatic Wheel Balancers and found cornering to be greatly improved. I pulled a trailer across Australia for about 10,000km and the front cupping came back quite severely. When I returned home I did not use the trailer for about 1000 km and the cupping has pretty much gone and is getting better with the more distance done without the trailer. I believe the fitting of Centramatic's to my Wing was money well spent.
