The 2001 srx came stock with a 40 pilot, the 98's had a 42.5 the mountain max had a 45 pilot, i just put 42.5's in my 2001 Srx 700 and it seems to be starting on 5 pulls rather then 12 so i hope its better,

That could have something to do with it but my 00 has 42.5's and its much more difficult to start than my 98 ever was. For some reason it takes a lot of pulling to get fuel into the engine. Especially if its cold.
 

Had the sled running yesturday after 2 hours of pulling and still this morning it will not start again

For mine same day first pull all the time. After a week 5-7 pulls. First start of the season 100+ pulls. This year I tried rocking the primary clutch didn't help. After 100 pulls I got the plugs out, added some gas and it started first pull. My choke cable is adjusted properly. I looked everywhere to see the gas tank vent tube so I can pressurize it. Couldn't find it.

Which one is it?

#18 is the vent tube. Look for it above the left foot rest behind the cowling. Many pro-actions have it connected to the steering gate.
 
it is abit embarasing sometimes lol... but thats just because my friends dont like yamaha... well most of em dont.. so when i spend a good 10 min reafing on the pull cord to get her started...their like... sooo still think going yamaha was a good idea?....
 
They can all be tuned to start very easily. You just have to spend the time to find the underlying issue(s).
 
Mine is getting fuel but no spark, I had it running yesturday and riding the sled in the yard, now I pulled the sled over and over but still won't start, i'm going to be looking at it a little closer tommorow any thing i should be looking first brfore I rip into it
 
Its not a consistant problem, I've owned two 1998's, one is very hard to start the first time every year and the other starts on the 3rd pull after sitting all summer.

On the hard starter this year I did the usual ether and plug dance for about 40 pulls before it would start, after it started I thought, maybe its the fuel pump getting tired. So I orderd a new pump and installed it yesterday, On the first start with the new pump I left the airbox out so I could watch the fuel lines, they were about half full, the sled started right up and started idling fine, I was watching the fuel lines while it was idleing and they were not filling up ? The sled idled for about a minute then died, It was just running on the full float bowls from the first start of the year. Why dident the running engine with a new pump fill the lines?? I resumed the usual ether and plug dance all over again, the whole time watching the lines, when it finally filled the lines and started it was because I revved the motor up to 7 grand for a second, then it filled the lines instantly and ran normally.

I was looking at the fuel line coming out of the tank and it's a bit weird how its routed, it comes out of the tank and goes "uphill" to the top of the airbox and then "downhill" to the fuel pump. I wonder if you routed the fuel line directly to the pump if it would fill the lines normally?

That's kind of interesting. I could see the "uphill" path the fuel needs to make being a bit of a problem if the fuel level was below the bend or high point but with a full tank that slight uphill shouldn't matter. It almost seems that the fuel pump isn't strong enough when just pulling the motor over.
 
I'm begining to believe the same thing, I think it needs a stronger pump, or a different fuel line route or both. Some of the pumps do work, but it seems like most people have this problem.

Between myself, my Dad, and a friend of mine, we've dealt with 9 different sleds; 98 Sx7, 00 SX700R, 00 Vmax700, 01 Vmax 700, 01 SRX, 2 02 Vipers, 04 Venture 700, and 07 Rage GT. Not one of them has ever started easy after sitting more than a week or so. 6 of them were purchased new from a good performance minded dealer. I, too, wish there was a solution.

choke them before u kill the motor
 
There is the filter in the tank, the vent to the tank, the line to the fuel pump, the pulse line from the engine to the fuel pump, possible crud or machining debris left in the fuel pump by the supplier, the lines to the carbs, and then the carbs themselves with all of the fuel circuits, and also the health of the engine itself. I am convinced that if all of these are in good shape, it will start easy with good fuel and will not lose prime.

Many people seem to be experiening this problem with their SRX's. My carbs are as clean as you can get them and I'm still finding it difficult to start. I have a 00 now but my older 98 never had this issue. I think it might be the "nature of the beast". One thing I didn't look at though is the fuel pump. Its almost as if the carbs are always emtpy of fuel and your trying to prime the gas through to fill the carbs.

Hey, don't see too many on here from Amherst. Of course, I can't reveal my identity on here!!lol. I might loose some of my hard earned credibility. I will say that I'm from Parrsboro originally.

Yeah, what's going on? So many people running the SRX's around this area I'm gonna have to guess who I'm talking to. Colin??
