I have a 2002 Eton Viper 90 that is not getting any spark to the plug. Any ideas on what to check?

 

There's a wiring diagram for the viper 90's on anythingATV.com. You may have to download the manual then look inside to find it.

Which viper 90 do you have? RXL90 or RXL-90R? The wiring is substantially different between the two.

 

Update:

Got the bike started, however it will only idle for a few seconds and then it dies. If you press the throttle it bogs down and dies. It does not have the manual choke on it....could this be a problem?

 

It could be the choke but it also could be a plugged jet

 

That was it. Saturday morning I removed the carburetor, disassembled it and gave it a thorough cleaning. It did not appear to be very dirty but after I reinstalled the carb, the little E-Ton has been running great. Thanks for the help.
