I figured this was normal but I will ask anyways. The sled wants to turn over quite a bit when its cold starting before it will even idle. Even then it will stall a couple times before you get it going. Carb cleaning issue? Normal? It starts right up once its warmed up. Just have to barely bump the starter and idles and runs smooth. Also there's a light for coolant on the dash that comes on when you start it. I figured it was a low coolant temp light, meaning let the sled warm up before you take off. The light does turn off after a couple mins of warm up time.
Thanks for all the info
If you don't have the choke on, it will not cold start well. The choke lever should be on the left side of the handle bars on the under side of the HI/LO headlight/hand warmer pod unless it has been relocated. My friends Vector starts right up at -20 F so long as it's choked. You only need to choke it for a short period of time (like 20 seconds or so). If you leave the choke on after that, it will run rough and eventually stall out due to an overly rich condition. When cold starting, I usually wait until it starts to run a little rough and then put it to half choke for about a half minute and then totally open the choke. It will high idle until it finishes the cold start/warm up mode and then drop to low idle.
The low coolant light will come on until it goes through the warm up mode. Once it has gone through the cold start mode, the light will go out and and the engine will go to low idle. If the engine is warm, it won't go through the warm up mode. I've read that you shouldn't touch the throttle until it goes through the warm up mode as it can foul the spark plugs.
Make sure that the choke is on. If that doesn't fix it, make sure that the choke cable isn't broken.
If none of this works, you may want to check the spark plugs to ensure that they aren't fouled.
The Yamaha four strokes usually cold start with a few revolutions of the motor unless it is very cold (like colder than -20). I started my RX a few days ago after sitting all summer and it took about ten seconds of running the starter before it fired. Now it fires right up.
A short story of when I bought my RX.
It was February and -36 F in Glenallen, AK. It had been colder in the preceding few days and I got stuck in Tok, AK for two days because it was -64 and my truck wouldn't start. Two days later, it warmed up to -48 and I was able to get my truck to start. I hadn't bothered to plug my truck in since the thermometer in my truck read -40 and I have been able to get it started at -40 in the past. I later found out that -40 is as low as the truck thermometer goes. It was actually much colder.
When I got to Glenallen, it was -36. The sled hadn't been run since August when the guy I bought it from put a new battery in it. I was coming into Glenallen and got cell service about 15 minutes before I got there and called the guy who was selling it. He was concerned that it may not start because it was so cold (he had it stored outside) and it hadn't been started in so long. I got there and he choked it, turned the key for about 20 seconds and it fired right up and purred like a kitten. That sold me on that sled.
Hope this helps.
