I picked up a 2009 170 with the vent racing intake, 26mm carb, 180 big bore kit, and I don’t know if it has an upgraded head or not (I’m not sure how to tell). The engine is fairly fresh with just a few runs on it, but the tuning was horribly wrong. Not a little, but waaaay off. I’m in the process right now of getting the carb setup correctly so we can see what this little machine can do!
I’m hoping it will last my daughter 2-3 years, so we can then upgrade her to something like a 570 side-by-side (she’ll never use the 800/900/1000 power).
Me, I’ll keep with my dirt bikes, and we’ll see how my son grows, but for now, he’s sticking to dirt bikes too.
If anyone in Colorado wants to meet up and you have one of these little 170’s, let me know!
