Run what the MFG tells you
I am speaking from being a past Yamaha dealer in the late 90's early 2000. When I first opended I was bombarded by mill reps and was fortunate to learns lots about batteries, plugs, oil and etc. Of course most were biased but there was a resounding similar tone when it came to plugs whether NGK, Champion or Spitfire.
Run what came with the sled ! The engineers that designed the motor most likely tested what plug would perform the best, hence the stock plug reccomendation in the manual.
I can tell you from experience with Yamaha that the NGK plugs fouled less, and more specifically the SRX took a BR9ECS and would not run as smooth as the BR9ES. We had numerous customers who would bring us "crappy running" SRX's only to find out they were using the wrong plug, as a matter of fact I think I remember Yamaha issuing a TSB regarding that exact thing.
My brother has a 96 Polaris XLT that fouls NGK's every trip but if you run the stock Champions, no problem-go figure !
Run what ya want but my point is, We are not engineers so dont try and out-engineer the mfg's. Yes, in a pinch most will run on anything as long as they fit but is it really worth a few bucks when we have such limited time to ride.
good luck !
