When very new my 2011 started easily cold, but sucked when warm. After 15 hours of use and a few very hot heat cycles from riding tight singletrack with some idling waiting for traffic to clear obstacles, it is easier to start.

I smell a Yamaha TROLL :devil: . There is no way a tech from any yamaha dealer ship would come on here asking a question like that. They would call tech support. LOL the things you read on the internet. I think i'm going to go copy and past your question in the Honda, Suzuki, Kawasaki, Ktm, Tm, and so on message boards and see if I can create hysteria.

You could be the real deal and if you are i'm sorry to allege such a thing, but for example I work on generators. If there were a TT for generators and there may very well be but I would not go on there asking question about problems with new equipment with out getting permission form say Caterpillar or Cummins or Kohler

It's def a mapping problem. I run into this issue often when we uncrate our rmz's. Plug the bike in and see if FI codes are tripping off. If no codes are shown plug in the GYTR power tuner and play with the fuel mapping. If that doesn't help call Yamaha's technical support line.

You work as a tech for Yamaha and are posting here for support?
Have you considered calling Yamaha?

Typical cold blooded Yamaha?? Hahaha! This made my day! I may have gotten lucky... but my 2013 450 starts great, and so does my 2010, as did my 07', my 04' WR had electric start, so it started like a dream. My fuel injected 450's do require 4-5 good kicks when cold and the choke is pulled. My point... I suppose... is that even if you are having trouble with 2013's, Yamahas are not typically tough to start if jetted correctly, and the top ends aren't worn out. Thanks for the good laugh though! :thumbsup:

My 2012 YZ450 starts great. When it is cold pull the cold start knob behind the left radiator and it starts 3-4 kick every time. If you stall it out it needs to be cleared out. Hold the trottle wide open and give it 3 light kicks, shut the trottle and give it 1 one hard kick and it starts right up. When the bike is warm rev it a couple times and shut it off. Starts first kick every time. They do load up easy making it hard to start but clear it out and it will start right up

They probably just need some good break in time. This has always been my experiance with brand new Yamaha's. We typically put a good 5 hard hours on them before they get easier to start. By the way my background was being a heavy equipment mechanic. I have been building MX engines for over 10 years now and love it. This IS a good place to get questions answered and dont ever be bashful just because you work at a dealership. Theres lots of helpful people on here. :thumbsup:

Never had problem starting mine ( its a 2010) and have used cold start knob 1 time in three years...it was 17 outside. Just bring to tdc and then kick. Always 3rd kick cold for me and just figured has to prime or build fuel pressure.

Both my 2011 and 2012 yz450f was very very hard to start when brand new...specially when it was cold outside.

But after a couple of hours they both became easier to start.

Why would a engine have to be broken in to start easier? Makes no sense to me.
