Hello,

I have had my son's 2003 E-Ton Viper 90 since it was new. It has run great but just died one day out on the trail. It will start up just fine and then run for a few seconds (even at full speed) and then either bog down or completely die. I've heard of problems with automatic choke so I ordered and replaced the auto-choke with a manual one but to no avail, the problem still exists. Once the engine bogs down, I can play with the choke (turning it partially on) to keep the engine running better but it's back and forth after that. I've also replace the fuel filter, checked the spark on the spark plug and filled the tank with gas. I'm thinking the next step is to completely remove the carberator and clean it out but it's so hard to even get to it since it doesn't appear I can remove the plastic without first removing the handle bars. Just wanted to see if anyone had any other suggestions or recomendations before try breaking down the carberator (including a simpler way to remove it).

Also, would having a "weak" battery cause any problems like this? After the 4-wheeler starts and runs for a while, the battery is strong enough to start it, but initially, we have to kick start it. I'm trying to get all the life out of this battery I can since I have to replace it about once a year.

Thanks,
Nathan

 

clean carb, check compression and get a new battery with a battery tender. it will extend the life to about 3 yrs

 

my son has a 2006 e-ton it had about the same problem I took carb off and cleaned it blew out the jets it seemed to run fine now i'm having different problems but thats a whole other story
