Wednesday I took my bike out for the second time this year. It was about 0 degrees when I left, everything was fine. I parked it for a few hours and then headed home at about -4 degrees.
After a couple minutes of riding I heard a constant high pitch squeal/whine coming from my bike. If I recall I had just finished giving it some throttle and I noticed it when I was easing off. Really hard to say where it was coming from but probably the mid/front half. It was quite loud, anyone I was passing would have most likely heard it. I pulled the clutch in and it kept going at the exact same pitch. I Started braking and it continued for a long time, all the way down to 30-40km/h, then changed pitch once and about a second after cut out completely once I slowed down enough. I started up again slowly and it was ok but once I picked up speed (60km/h?) it started again. So I pulled over and rode around for a minute on an empty street and it was fine at low speeds. Didn't happen again for the rest of my 15 minutes ride, although I was taking it really easy.
I know its a pretty vague description, but any ideas what it could possibly be? I rode one other time this year in slightly colder weather and I never heard this. The bike is a 2012 Ninja 250, it has < 4000km on it. Weather is beautiful today so I won't to take it out, but I don't want to cause any damage.
UPDATE: On second though I'm not 100% sure if it was a constant pitch all the way through 80-30km/h, it may have fluctuated slowly. But I do know it wasn't changing pitch in relation to the engine speed.
