  1. You guys see the Polaris recall of 22 to 25 utvs? Missing bolts in frame and roll bars..oops...probably not good if you jump or roll I would think...but that's just me...🤔

  2. The QC on any new vehicle all depends on how thorough the inspectors/installers were on a given day. That's why I make it a point to inspect all new vehicles for this exact reason. You shouldn't have to but reality says otherwise.

  3. Update to my original post: 2018 Massimo MSU 700 burning oil. I disassembled the top end of this HISUN based 686cc motor over the weekend. The cylinder head was unremarkable other than the combustion chamber was completely involved with a heavy black soot deposit. That was to be expected as the unit was burning oil. The piston top was dark brown but again to be expected. I actually expected to find a stuck ring as I removed the cylinder. This was not the case but I have to consideer that a ring could be siezed while in position in the piston ring groove but may immediately "free-up" upon extraction from the cylinder. The cylinder walls while shiny were not scored. There was no detectable (fingernail test) ridge at the top of the cylinder. Of course there was no trace of any original honing crosshatch as the engine has about 350hrs on it. At that point I had not discovered an obvious causal factor for the excessive oil burning. An interesting observation is that neither the top compression ring or the second ring had any identifying marks on them to: 1. Identify which was which and 2. Denote the top of the rings. I am the original owner and know that this engine is as "factory delivered" -- no intermediate ring replacement has occurred -- factory install. The piston skirts did not indicate unreasonable wear ( I have not measured the piston yet). Today I received the top end rebuild kit. As I began the process of measuring the new components I decided to evaluate the existing ring gaps from the smoking unit. Here is what I found: Top (compression) Ring Gap: .051 inch. Second Ring Gap: .125 inch (That is not a typo: .125 inch). At that point I did not evaluate the Third (oil control ring rails) for gap. I am at a loss as to how to explain these numbers. If this were attributed to ring wear I would have thought the cylinder walls would have at least indcated more wear and there would have been at least some discernible ridge. I will measure the piston itself tomorrow. My thought is that if this is indeed ring wear that the piston measurements will reflect significant wear as well. Of course the other possibility is that this is manufacturing/assembly failure and the unit was delivered in this condition. What is strange about that theory is that the unit began smoking excessively only recently and the condition onset was rapid. I have maintained the air filtration system responsibly and prior to disassembly I inspected the filter/the intake ducting to throttle body/the throttle body itself/the intake manifold runners and the intake chambers in the head. No sign of contamination. At this point all I will reassemble with new cylinder/piston and rings. I will check/set end gaps to FSM specs. Additionally I will install new valve stem seals even though the originals appear to be fine. I would appreciate any and all opinons/observations/conspiracy theories etc that may help explain these strange findings. Thank you, Chile

  5. Hey everyone, I’m in the market for a UTV windshield that can withstand extreme conditions, including high winds, dust, and off-road impacts. I’ve seen a lot of options out there, but I’m unsure which one will provide the best protection and durability. Does anyone have experience with windshields that excel in these environments? Are there specific brands or materials you recommend? I’m particularly interested in options that offer both durability and clarity. Any tips or personal experiences would be greatly appreciated!

  6. I’d recommend checking out the utv windshield, they offer durable polycarbonate options that handle high winds, dust, and off-road impacts really well. Their windshields are scratch-resistant, provide great clarity, and are designed for extreme conditions. I’ve seen good feedback on their fit and toughness, especially for rough terrain.

  8. A little late on this but similar to what has been discussed above, plexiglass is junk. I had one on my Can-am Commander and just threw it away. It was hazy and had terrible visibility. I would suggest getting a laminated glass windshield with vents. They are well worth the extra money. There are a lot of companies that make affordable aftermarket windshields as well. I have personally used Alpha Windshields and been very happy with their product. https://www.alphawindshields.com/ just depends on what side by side you have. If they don't make one that fits then there are quite a few companies that make a nice product. That is my suggestion.

  9. I agree, while mine doesn't fold you can take either half off. I will have to take the top off if I use it much as it's so bad I can barely see thru it. Oh, its plexiglas.

  10. Aha! Even the big name brands have problems 😉
