Brute Force -- hard to start when cold
My 2005 Brute Force is almost impossible to start when the temps are cold. It takes about 3 minutes of cranking, giving it gas (with the choke on), then once it fires up, it takes another 1-2 minutes of giving it throttle before it will idle by itself.
With the amount of snow we've been getting, I've been firing up the ATV daily to plow snow..
Any suggestions on resolving this?

My dealer's mechanic ran the tests for Yamaha when they were trying to figure out how to fix the cold starting problems on the new Grizzlies. He found that by putting in 30W oil instead of 40W oil, no more problem. Twas a viscosity problem at low temps. I don't know if that would work for your Brute Force or not.

Hey BF.
You have the 750 right? Not sure I have ever heard of a cold start issue with any of the Brutes. My 650 SRA, which is carbed a bit different than the 750, does not really have much problem starting in the cold. Usually choking it on full without any gas until it starts, then just moving the choke down as the revs pick up. Then it idles good after 20-30 seconds of having the choke on. I just did this a few days ago when it was about 25 out, and I had not run it in a few weeks. Like said above you could have a choke issue or a jetting problem. I know that any changes in temp or humidity causes mine to act funny. Usually it does not affect starting though....hmmmm.
Let us know what you find out.

Don't they use a multi-viscosity? If you're using 0-40W...it's 0 when it's cold.GrizzlyGuy wrote:30W oil instead of 40W oil, no more problem.

Get the valves adjusted - specifically the exhaust valves. I'm willing to bet that they've tightened up. My prairie was notoriously cold blooded - to the point where it was becoming less and less enjoyable to ride. I just did my 100 hour service on it, and did my valves - the intake was spot on, but I could barely get a feeler gauge under the exhaust. Now the thing is a completely different bike.
