Howling Noise

[aussiegordo]

hi to you all from down under, I have a 2016 F3 limited. It has 15000 miles and is not ridden hard. At about 40-44 mph i get a howling noise from under the tank region belt engine area 4th fifth or top gear .I have have been told this is probably a harmonic distortion between the drive belt and the cog wheel. Has any one else experienced this and if so what is the fix. Looking forward to a reply

Welcome aboard Aussiegordo,

It more than likely is the belt.

I get the same thing at about 90kph (about 55mph) and drive through it. It's not good to have that happening and is hard on the bike. The speed at which it happens is related to how tight your belt, it's length etc but they are all around the same speed. You can get belt tensioners as a 3rd party add on... I believe Lamonster sells them. Just try not to drive prolonged at that speed where the resonate frequency is the worst.

Also Look at the front pully, there's been a lotta buzz, bout this, there's a fix from BRP, My Spyder F3s, does this @70 Km/h, but it goes away @72 Km/h, so it's not bothering me.
Front pully is most likely the cause for the whining noise, Spyders aren't the quietest ones...

Look for red dust on the front sprocket, that will tell you, you need to put on new sprocket.

I had a loud howling at about 54 mph on my 2020 RT. Took it in for its 3000 mile check and they realigned the belt. Most of the noise is now gone. It is down in the acceptable range.

I had the howling at 52-54 on my 2020RT. Took it back to the dealer and he re-aligned the belt and most of the whining disappeared.
