This may be a stupid problem. I have an 05 Raptor 660. It sat for a month without being used but would start and run. Yesterday I started it and let it idle with no prob. The thing was the gas was on reserve and the bike stalled, I guess cuz it ran outta gas. But now the bike won't start. It cranks but if I'm liucky I get one putter. Spark is good but it appears I'm getting no gas. The **** is clean, no clogs. It's start with starter fluid but only for a sec til the fluid is all burned up. Help? Anyone?

 

1. Unplug the fuel hose to the carbs, make sure there is fuel flowing.

2. Make sure there is spark at the plug.

3. Make sure the carbs didn't come off the intake boots.

4. The valves may be to tight. Raptor valves wear and get tight and don't seat. It really gets tough to start.

It should start if all of the above is good, unless it is flooded.

 

Did you try filling the tank up? Maybe you were too low on reserve to fire.

MIke.

 

Okay, the hose to the carb flows fine. The plug has spark. The carbs are not off the boots and the engine isn't flooded because I smell no gass. It seems like there isn't any gass to burn. How can I check the valves? Some people say the floats are stuck open and some say some stupid sh*t about needing an oil change. Jeez I just wanna ride!

 

Also, I let it sit for an hour yesterday and got it to run with the choke on (90 degree weather so choke should not be necessary) and it would sputter and backfire then it quit after a minute. Then, no start situation again.

 

So no help? Anyone? C'mon this should be easy...
It will start for like a minute with thechoke on if it sits over nights. Any ideas? Please???

 

so if you are saying that when you do get it started it quits after a minute.. I would definately say it was something with the carbs because mine did do that. Since the raptor has to carbs, if they aren't in sync with eachother it won't run right.

 

Yeah that's what I hear. Do you think it's something with the floats maybe? You think they might be getting stuck shut? I'm gonna take the carbs off but I'm not sure what I'll find. I appreciate the help.

 

Pull the fuel line off the tank end. Blow into the line with compressed air if you have it. Use lung pressure if you don't. This can free up a stuck float.

 

Okay, tried that. When I shot the compressed air in, the remaining gass in the carbs shot out the other end and it seems clear but the bike still won't start. I'm gonna blow it up!!!!
