Posted here a month ago or so regarding my 04 SX Viper with DCS light coming on every time I ride. Everyone offered lots of help which was greatly appreciated.........so I decided to take it back to the dealer for some more work. Dealer spoke to Yamaha directly and was told the wiring harness can be a problem on that model and year of Viper so they re-routed the harness. While the carbs were off they jetted them up for me to make it run a little richer as I was advised by numerous members on here as the fuel could potentially be the problem. Always run 91 octane in it and the sled only has 700kms on it......its brand new.
Carbs cleaned, powervalves cleaned.........dealership thinks now maybe sensor should be changed. I have my doubts. Light seems to come on once the sled is warmed up within a few kilometers of driving it and then from there on. If I squeeze the throttle it usually doesn't come on but when I let off and maintain RPM's around 7000 it comes on. If I let off and then punch on it then it won't come on. If I slowly increase the RPM's then it comes on.
I know this thread is long winded but I am frustrated as hell with this 'new' machine of mine. I have not been able to drive it all winter because of this issue. Not to mention I am $800.00 deep into fixing a light that is not fixed. Where do I draw the line and what step do I take next. I would LOVE some help. Thanks in advance.
P.s.- Everything is stock on this snowmobile.
