I just passed 20 hours on my 2016 Viking but my exhaust does not get red hot like everyone else's I can tell it's running rich because you can smell the dilution in the oil. I guess it's possible that rings still need breaking in but I believe it's running rich. Also on a cold start it always needs a second cranking. First cranking it fires up but sputters out. I'll even cycle the key so the fuel pump primes 2-3 times. I've even tried putting it in neutral and slightly depressing the throttle and on a cold start, it always takes 2 tries. I'm wondering if the stealership may have richened it via TPS/programming as mine had 16 miles on it and was probably used as a demo.

It's also 20-30 F here so that could be it. My Rhino always started on the first try. I really wish you could enter diagnostic mode like you could on the Rhino to check TPS values. I guess I could check ohm values of the TPS, it was so convenient reading the display in diagnostic mode. I suppose I'll break down and get a power commander or Yamaha diagnostic tool (betting that's just as expensive)

Started her up again today and she started on the first try. Exhaust is much clearer as well. One tip off that it could have been a loose spark plug wire was it would bog down occasionally and then recover.

I have 30 hours on my 2016 and have never seen the exhaust red hot. It always starts on the first crank other than when it's 10* outside.

I never seen my exhaust red hot until I firmly seated the spark plug boot, which was definitely loose causing the rich condition. The glowing exhaust is most likely to happen while sitting idle for awhile. I just added a heat shield as well and rear diff now runs cool. Feel your rear diff after a run and you'll see how hot it gets from the header heat (run in 4WD and feel the front diff and you'll see it's cool).

I'll give it a shot. I did notice all sorts of new smells with the new machine breaking in. My problem is that I have not really been able to get really good seat time yet. Usually its 15-30 minutes around the property so far. Hopefully this summer I'll get out more.
