What kind of tuning did you do? Have the carbs been cleaned?? Properly!!

ya the carbs were cleaned by the yamaha dealership i had the full pre season tuneup done by yamaha. I was just doing some minor clutching tunning. and it has never done this before.
Check compression. Viper has lean spot in low circuit, just cost me an engine. NEVER run the viper slow with stock head
