I have a buddy that has a new M8 and he left it out side after riding it and now it will not start. Pulled and pulled and will not start. We pulled it in the shop and warmed it up, still would not start. pulled the plugs and when you pull it over gas shoots out the spark plug holes like two geysers. anyone have this problem yet??:(

Maybe?

How do the plugs look? Fouled?

Did you check spark?

Is the key on? not being a smartass but I have seen this before, I leave my key on and just use the kill switch so maybe check this?

Fuel, Air, and spark should fire? it is an 2010 warranty? good luck.

10 M8 High Compression

I have a buddy that has a new M8 and he left it out side after riding it and now it will not start. Pulled and pulled and will not start. We pulled it in the shop and warmed it up, still would not start. pulled the plugs and when you pull it over gas shoots out the spark plug holes like two geysers. anyone have this problem yet??:([/QUOTE

Yes I have noticed my 2010 is harder to start. Must be the higher compression = harder to pull over.

I had a similar situation on a very cold morning, everything in the on position, on second pull it fired and died. Several pulls later decided it was not going to start. Had no idea what good be wrong so started to get ready to bring inside. Just before the hassle of moving in side tried again. First pull nothing, second pull cracked throttle a bit and it fired. I think they are flooding, just to hard to pull over when -20. Here's what I have been trying- turn key off for several pulls, loosen things up. Turn key on and pull as hard as he!! :D

My buddy missed out on riding last weekend with the EXACT same issue. He was able to get it started first pulling the plugs, airing/ warming it up in the garage for a while, put in new plugs, which were immediatly doused with fuel. Finally started by holding the throttle wide open and pulling. Said it garbled at first and then fired up and is as good as new. Sounded like it was flooded?

Was it parked slightly down hill and full of fuel? I've noticed that mine will flood out very easy in this position. Like mentioned before.....shut the kill switch off..give it a couple pulls...turn the kill switch back on and it should fire right up.....good luck

We had the same issue this weekend, pulled a plug and pulled it over a few times. When we put it back in I held it open and pulled a couple times and it started. Ran like it was flooded then cleaned up and ran fine.

I had the same problem today when I went to unload my sled. Started 2nd pull, quickly died and would not start. I gave it ten minutes or so and tried again. About 10 pulls and nothing. Held the throttle open and 2nd pull she fired and ran. Seemed very loaded up. I'm blaming my girlfriend since she rode it last! This sled seems to load up pretty bad if it's not opened up fairly often. Point is this.... don't give up on it and miss out on riding. Play with different throttle positions and you should get it started.

This happened to me a month ago. I put a post up and got lots of responses, thanks. It was flooded. I pinched the fuel line with some vise grips and held the throttle wide open until it started.

Ya we pulled and pulled on it last night. Took out the plugs and had the key and kill switch off and gas would come out of the plugs holes for as long as you wanted to pull it. Put it in the truck and back to the dealer it goes. It's their problem now.

On a side note I love my Yammie even more now!!:D

Fuel Pump

It reminds me of the fuel pump on the daughter's Polaris 600. Really could not even pull it over, pulled the plugs and it was a geyser of fuel. The pipe was full as was the case. I rebuilt the fuel pump to no avail and finally replaced it, that solved the problem.

The 2010 has the fuel pump inside the tank though. I guess it could still go bad and allow gas to fill the engine. I have not had this problem with mine (fingers crossed here), but it is hard to start. I miss the choke. I have always started mine with my left and cracked the gas with my right. The dealer said this is a no no on my new kitty though as it will flood it. So make sure you are not touching the gas when you first try to start it. I do flick it once or twice before I pull on the initial start and I have learned to do the initial pull or two just to get things moving before I really pull.

So let us know what the dealer says.

Sounds like injectors may be sticking. If this is the case Lightly tapping on them with a screwdriver may free up. On my 05 F7 I went through 2 fuel pumps, started looking into why and found out the in tank pump is lubricated by gas. Our fuel now days is oxygenated, this makes it "drier" meaning less lubrication. The local dealer suggjusted adding about 2-3 oz. of injection oil to the tank at every fill up. Hardly enough to effect the fuel/oil ratio, but will lubricate the entire fuel system, pump to injectors. Couple sleds and 4000+mi. later, have not had any other fuel sys. issues. Doesnt take much just enough to increase the lubricity of the fuel. Good insurance cause those pumps/injectors arent cheap! Let us know what dealer found.

Went to drop it off at the Dealer and jump in the back of the truck to get the sled out and it poped off on the first pull. Buddy feels like a douche now, probably won't show his face at the dealer for a bit.

But it still has an issue. Just because it started today does not mean it is going to start on Sat. when he wants to ride. It is a new sled and is well under warranty. He paid a lot for the sled and he should never miss a day of riding. Never be intimidated by a dealer or anyone else. Since it has an issue, make them fix it.

Did he run 12 oz oil in his first tank of fuel? I ran 12, ran it down to about 1/2 a tank, filled it, and added another 6 oz of oil so I knew my first 100 to 150 miles had plenty of oil in the gas for break in. You don't have to be precise; I was probably 16 oz and 8 oz, but you need to do it.

Tsnowak may be on to something.

When it's in the single digits it's almost a given that my 08 M/8 won't start. I give it one pull to limber it up and another pull with about 1/4 throttle and on the third pull it will usually fire. Now remember this is when it's mega cold outside. Now if it's in the 20's it will start right up >>>>.
