150cc or 165cc?

Thinking about a couple ATV's for the wife and I. I initially thought the Bull200 or the Coolster 3175u with the 169cc engine. During some research I found the Coolster 3150DX4 that looks to be close to the same physical size with a 6" smaller track and a 150cc.

I can put a big block kit on the 150 really inexpensively, and parts for the 150 GY6 are pretty cheap.

I think (can anyone confirm) that the 169 is going to be a GY6 K Block motor for which parts are much more expensive.

This has me leaning to the 150, plus it's about $300 cheaper.
Any of you experts have thoughts?

I have a 2014 Coolster 3150DX for my wife. If you keep up with the maintenance on the ATV's they will last a long time. When i bought it i figured if it lasted a few years i was happy. Here it is 6 years old this month and still runs flawless.
