tried to start my sled for 1st time this year, won't go. Ran when I parked it last year. Will only start if I squirt a little gas down the carbs, but stalls shortly after. I don't think there is a fuel shut off, so wouldn't be that. ( I think I would remember if I shut off?) could it be fuel pump or filter? I put new gas in tank already..
Thanks, Rob
 

Have you done the basic preseason work on it? Cleaning the carbs is where I would start. Once cleaned and re-installed you can pressurize the fuel tank with either compressed air via the gas cap or blow into the vent tube located in behind the left footwell. Fresh gas and plugs are also a good way to ensure that it will start fairly quickly. My Viper would start in about three seconds after performing the above work.


There is no factory fuel shutoff for the Viper.
 
what i do every year for the past 15 years was pour a little gas down the middle cylinder. Probably not good but it works
 
In the spring once riding is over, I usually drain the gas tank, take the carburetors off and drain all fuel out of them. Then after a few days I will put them in a box and store them inside. Sometime in late fall, I will pull them apart, clean them up, and install them on the sled with some fresh gas.
 
I have several sleds. Process is same for all. Syphon gas,take top of air box off. Fire up sled and let idle for a few sucking last bit of gas from tank. As sled starts to sputter I will hog 2 cans or so directly into carb boots. Put top of airbox back togther just far enough so I dont have to try and remeber what went where. Pull plugs and give a snort of fogging oil down each hole. Pull belt,primary and give they whole engine bay a coating of fogging oil or wd 40 to stay off any corroding. Lift sled enough to take weight of suspension and back track off a little bit. Takes and hour or so on each sled. Carbs are almost always spotless in the fall when I re-assemble for the next seasons festivitys!
 
Thanks all. I took mine to get looked at and he cleaned the carbs, and said the fuel pump also required a diaphragm. Looks like I'm ready to go.....now to find the snow, it all melted here
 
Can you get diaphragms for the Vipers? I thought we couldn't, had to buy the whole unit. Am I way off here?
 
I usually always have a hard time starting after sitting for the summer. Gas down the jugs a good 4 or 5 times before she stays lit. I guess the fuel system really drains itself out, and pulling the rope only trickles the gas back into the carbs. You'd need to pull over 100 times to get enough gas in there.
 
Carbs cleaned, three plugs and a diaphragm the guy had new on the shelf. $155. He said don't use engine fogging oil, clogs carbs. He said I should get power valves serviced next year and clutches cleaned. Good advice, I think.

Clean the power valves and clutches atleast once a season.
Fogging has never clogged up my carbs.
