RX 1 A NEW NOISE !

[Obone1]

Hi fellow Yamaha enthusiasts. I have a 2004 RX 1 with 10klm on it. I had it out about 3 weeks ago rode as it should always been bullet proof. Its been -33c here on Lake Simcoe , however today at -14c decided to take the sled out for a ride.
Started right up, battery tender always plugged in, newer oil nothing changed .
The engine is making a changing noise, gas spitting out of carbs 3 & 4.
Is this motor toast, is it worth repairing?
Sometimes we can't catch a break!
I tried to post a video, says its to large at 2 seconds

Something may have frozen in the carbs if any moisture present at those very cold temps. Put it inside if possible to thaw things out, or take the air box out and place a small heater in there. Once all thawed, put the air box back in and try again. You never know, could be something simple. That changing noise doesn't sound good though.

get it thawed out. sounding like it could be ice. if it runs on all 4 when warm, odds are needs carbs cleaned.

Tks everyone. The challenge was the idle on the machine was to low, typically at 1350 rpm, was 1000rpm. The cold was a factor as the machine took sometimes to warm up and with the low rims the Helex was even loader than normal. The rpm was adjusted the clutch makes the typical Helix chirp.
