Ok I know most guys,myself included,probably figured they'd read and commented on just about all the hard starting issues relating to the SRX they could ever dream of and to be honest I figured I'd been pretty lucky with mine in that neither my 98 or my 01 had really given me much trouble when it came to starting.Well let me relate my latest experience.On Saturday my son and I were pitching in on some trail cleanup after the latest ice storm come through,we trailer out to where we're going to leave from and get to parking the truck.Both sleds are on the trailer,the 98 had been running on Wednesday prior,3 days,but the 01 hadn't been run for a week and then only for about 15 minutes.I just fueled up the 01 before we left but the 98 had lots of gas for what we were going to do.Anyway I park the truck flip the top up and commence to starting up the sleds,I picked the 01 first just because it was on the left side of the trailer,force of habit.

Without too much exaggeration I'll bet I pulled that sled 40 times.It fired up at one point but stumbled after about 15 seconds and stalled then I had to pull it again;it was acting like the carbs were dry,I couldn't believe it this sled has never acted this way before.To put this in contrast my 98 FIRED on the first pull and then started on the second,I couldn't believe that either.
To answer the obvious questions:
1. Yes the carbs are clean
2. The choke cable is adjusted to max opening and yes it was in the start position
3. I choked it to stall the last time it was running
4. No I don't have a fuel shut off
5. Yes there was some gas line antifreeze in the gas
6. Once running it worked like a top

I don't know if it would have made a difference but how many guys use a shut off when trailering?One sled starts right up and the other gives me the most grief I ever experienced,other than the first startup of the fall.
Things I will be checking as soon as I can get the sled back in my shed:
1. Choke cable adjustment...... make sure the cable didn't back off
2. Fuel lines for sealing or leaks.

Anything else you guys can add to the list I'd appreciate it.
 
Bad fresh gas? Ethanol? I once got a 5 gallon of fresh 93 from a local gas station and it had about honestly 1-2 gallons of water or ethanol in it. So it could happen. Could not believe it but it was. Needless to say that fueling station is off the list for gas in the sleds.
 
Sorry to hijack but why should you choke to stall instead of just hitting the kill?

If I were a betting man I would say there is some restriction in the venting on the 01's tank. Being near full bouncing down the road, sloshing around. Fuel expanded faster than air could be pushed out and started to flood it out. I have read on here of guys that routinely trailer their sleds installing fuel shut off valves to cure this.
 
I was told never trailer with a full tank because they have no fuel switch. When my buddy bought his new in 99 dealer told him yamaha said not to trailer with i believe it was no more than a quarter tank.

I have seen this happen more than once. Could very well be. I have also seen the reverse where the tank almost collapses because the vent is not allowing air in to replace the used fuel.

I also have to wonder if these sleds that start much harder in cold weather have the starter plungers cleaned, adjusted and working properly (orifices be must clear too). You need a significant amount of extra gas to get enough combustible fuel when very cold.
 
Well I'll try and answer as much as I can here. Never checked the plugs, to be honest I was so focused on getting the thing to fire up and pissdd off because it wasn't I just kept pulling. As far as not trailering with a full tank that wasn't an option, other than using a 5 gallon can once I got to where I had to go there wasn't any place to get gas.
I'll have to check the gas tank vent and make sure it's not kinked or restricted in any way, and I'll pull the carbs off again and check that the orifices in back of the plungers are clear.
 
Have you tried the mr funnel it separates water from gas when you use it to fill up. They are awesome. You can pour a cup of half water and half gas through it and the water will stay in the funnel. They are available at the yamaha dealers in Canada. For $20 to $30 they are well worth the money.
