DET
The biggest thing now with all of your new motors they try to save themselves through the electronics which you never had back a few years ago. That is why if you had severe DET you seen holes in the top of the pistons because the electronics didn't have a way to change timing or mapping and just did what it was set to do. Now through power reduction and mapping to change the fuel and timing you can allmost make a motor fool proof. Also motor design the pistons and dome configurations for burn paths and pipes have gotten way better so you do not see the detonation marks so much in the middle of the pistons as in the past. Your motors are just big air pumps with controled explosions happening ever second revolution and as they become more efficient you create problem areas that were not problem areas in the past. Manufactors do not like to re-tool every time there is a advancement in technology and will try to get every year they can out of a design. The costs to be the standard in any industry would put you into bankruptcy quite fast. Now can you imagine all of the changes Polaris and other manufactors have made the last 2 or 3 years all of the little and big problems that should of reared there ugly heads? Yes a few are still there like the motor issues and drive shaft issues. I looked at it this way. When I built my last mod back in 2004 and all of the little and big problems I had to go through to make a great sled and now I can walk into a dealership and buy a sled that has all of the same qualities and way more for probably half of what it would cost to build yourself it was a no brainer. People tend to forget about what it was like 1 year ago let alone 5 years ago. I jump on my old sleds once in a while to remind me of this. I am talking late 70 and early 80 stuff that I thought when I started was the greatest thing on earth!
