On a fairly long ride my speedo started acting up. Going about 30-40 mph the speedo needle started going slower till it read almost zero. I stoped and shut it off and on re-start it was fine for a while then did it again. Came to a stop, no shutdown, took off and OK again for a while then started going slow again. So I switched it to needle on RPM and digital speedo. Works fine all the time. The quad is bone stock with no winch. 24 hrs on unit. Dealer says he never had a speedo problem. I know if mine is doing it so are others. I kind of like it with needle on RPM but something is wrong somewhere. The thing is for the dealer to see the problem he will have to ride it at 30+ for a while and that is not possible.
