2017 800r DPS – Coolant Smell?

Hey guys, I searched the forum and couldn't find anything on this. I've got a brand new 2017 800r DPS that absolutely REEKS of coolant. It sat for about a month and then I started it up and let it idle for a good half hour and then took it for a little stroll in low. Stopped during the ride and saw some smoke coming from around the front left headlight. Took it back home and found a tiny bit of coolant on the left side radiator removable cover and some up near the top left above where the hose connects to the radiator. I ordered a high pressure cap, put that on, and cleaned up what had spilled. My guess is that it just got too hot from idling and possibly boiled over. I have looked, high and low, and cannot see it leaking anywhere since I got the new cap, but it stinks incredibly bad. I can smell it standing 15 feet away from it. It only starts stinking once it gets up to temperature. The coolant tank isn't going down, so I'm wondering if it's just from where it leaked before and I need to spray it off really good or what? I'm planning on replacing all of these bullsh*t pinch clamps with worm gear clamps soon. Anyone else had this issue? Thank you!

350L 4×4 input shaft bearing

I picked up a pretty 93 350L for cheap recently that had "transmission issues". I started pulling things apart and believe I found the culprit of the issues. It looks like the input shaft bearing cage blew and the bearings were just sitting in the hole, allowing the shaft to wobble any time the bike moved. Do I need to pull the whole transmission to press the old out/new in, or can it be done in place? I'm fairly mechnically inclined but all my work has been on motorcycles and this is my first time with ATVs. Any advice or help is greatly appreciated.

Which piston

I am wondering what piston will last long on a 1989 polaris trail boss 250 2 stroke. Had purchased a Namura top end rebuild kit on amazon but it didn't last a month. ANY feedback appreciated
