919 first gear whine

Hello all,

I recently bought an '03 919. The bike has some road rash, but I think I got a good deal on a low mileage bike and it's an absolute blast to ride.

The only mechanical issue I've noticed is a whine in first gear. It sounds like the whine some manual transmission cars make in reverse. I don't hear the noise in other gears and the transmission seems to perform flawlessly otherwise.

Any idea what this might be? Should I be concerned?

Thanks!

Thanks for the reply. My bike has a whine that only happens in first gear, different from the subtle idle whine typical of many Japanese water-cooled fours. And, like I mentioned, it sounds like the whine some manual transmission cars make in reverse.

Is this common for the 919? Should I be concerned?

Thanks again!

If you're hearing it while moving, check your chain to see if it's too tight.

I had the same thought. If anything, it was too loose. And yes, it is while moving, with little difference when the clutch is pulled in, but definitely road speed dependent. It completely disappears after shifting into second.

Mine does that. I treat it like a first gear indicator. It's not loud, and it hasn't changed - it doesn't seem to be a problem.

its just how it is....

being that its a naked with no fairings to stop motor sounds to your ears you hear alot more than you normally would.

That whine is produced by the fact that the first gear is a straight cut gear to handle the load. There is nothing wrong with the bike. Ride it and change the oil and lube the chain from time to time and you will never have any issues.

and WELCOME TO WT!

Thanks everyone! I'm glad it's nothing to worry about. Gotta fix some of the rash on the bike and maybe get a Delkevic exhaust...

Just popping in to say mine does the same thing. Like nd4, I treat it as a first gear indicator. Drop down from second and hear the whine, I actually like the sound.

Does this napkin smell like chloroform? Just kidding baby lemme buy you a drink.

I sometimes detected a more pronounced whine at low speed acceleration in 1st. Unless it's obviously loose, back off on the chain tension a bit and see if the noise is diminished. Otherwise, don't worry - be happy.

What parts are you looking for? Post up in the classifieds. Probably someone that has them.

I'm looking for a tank for my smoke gray '03 919, but I'd be interested in black or silver as well.
