    New Ecu flash for Yamaha Viper/Arctic cats 7000 w/POLL

    Thanks for the pic Cannondale. If the reluctor was out of phase wouldn't that cause it to run like crap all the time. After it comes up to temp it runs normal.

    Wider Ski for my Viper!

    I put on a set of C&A Pro MTX with Woody's slim jim dualy carbides last year. I talked with Eddie from C&A PRO at Haydays, MTX was his suggestion for the Viper. Awesome set up zero darting on trails and great flotation when you get off trail. Also changed track to Backcountry X 1.75 lug track.

    New Ecu flash for Yamaha Viper/Arctic cats 7000 w/POLL

    Totally agree with Cobra. Never had issues until Yamaha updated ECU flash. My has got worse with each flash. Doesn't make sense that it starts and runs perfect on high idle for 5-10 seconds then drops to 800 and dies. That's not valves.

    New Ecu flash for Yamaha Viper/Arctic cats 7000 w/POLL

    No cold start issues before last flash. It's on its 3rd flash. Stock flash always started first try. Second flash, supposed kickback flash, my sled would take 2 tries to start, but always started. It never backfired until the 2nd flash was done. Sounds odd that flashing the ECU would result...

    Sounds like its time to dump it since Yamaha is no help. Really loved the sled until the last flash in March 2019. Last ride of last season was near Lake Vermilion after the flash. Both mornings had trouble with cold starts.

    New Ecu flash for Yamaha Viper/Arctic cats 7000 w/POLL

    After last flash my 15 Viper cold starts are terrible. Long crank, starts then after 5-10 seconds at 1800 drops to 800 eventually dies. Won't start unless you crack throttle a bit then it starts. If you let off throttle it dies. I have to hold throttle for a couple minutes until it warms up...

    ST-X DX suspension to harsh

    I talked to the Yamaha rep at Hay Days this fall about the suspension set up on my 15 STX DX. I was getting bucked by rear suspension in the shutter bumps. I'm a big guy, 300+ with riding gear, but the set up theory should be similar. He told me to add the same amount of preload to fronts as...

    Blue LEDs on my 2015 Sr Viper. Can't wait to see how it looks out on the trail. Used a mini timer to automatically turn them off 5 minutes after I shut off the sled. Found the timer at http://www.3rdbrakeflasher.com/timer-c-68/multifunctional-5v20v-time-delay-relay-timer-5-amp-p-192.html Works...
