Guys, I've got a 1999 Honda Foreman 450S. It runs great, but smokes out the exhaust after startup until it warms up. I'm thinking the valve seals are leaking. I was wondering if there is a way to replace them without removing the head or if there's an oil additive that will recondition the rubber seals. Any advice?

Hey everyone,
I’m having an issue with my 2021 Polaris Sportsman 570 – the engine keeps stalling after running for about 10–15 minutes. I’ve checked the air filter, spark plug, and fuel lines, but can’t seem to find the root of the problem. It starts up just fine, but then loses power suddenly.
Has anyone experienced a similar issue with this model/year? Would appreciate any advice or troubleshooting tips you’ve tried that worked. Thanks in advance for your help!

I recently got my hands on a free 2004 Recon that the owner had zero information on the machine or the history. Long story short, a little troubleshooting and research revealed i needed to replace the timing chain for it to stay running. when i opened the case, it the chain was so horribly stretched, that the tensioner pivot arm had play between it and the chain! I also found the oil pump chain totally disconnected from the sprocket due to being completely worn out. I tore the whole engine down and rebuilt it from the bottom up finding little things here and there that needed to be replaced. Upon inspecting the top end, i didn't find any bad/excessive play in the crank, rod bearings or wrist pin. Now the machine runs great, but even after 2x adjusting the valves, the chatter is way more than you'd expect from a honda normally. My neighbor is an auto mechanic by trade, and i asked him to take a listen. the look on his face when i started it and it was chattering like that was priceless! He mentioned that maybe the valves themselves might be wore out or stretched. my question here: what all can cause the excessive rattle up in the valve cover aside from valves being out of spec? Everything else seemed to be in decent condition as far as rockers and guides go. I am fairly new to small engine/ATV repairs, but am learning as a hobby and have a fair amount of knowledge with how to do some wrenching. Thanks!

I have Grizzly 700 that has been pretty much totaled out in a bad accident, but it will still run and drive good...
Will this engine swap into any of the Yamaha UTV's like thr rhino and Viking 700's?
Was just going to sell it as is for a engine for someone who needs one pretty cheap..but been thinking about getting a UTV for the family and maybe find one with a blown engine cheap and swap it out
I already an excellent shape 2001 Big Bear 400 4x4 for us..but kinda been looking for a good used UTV for us and the grandkids on our property to play with
Not sure of the year..i can't remember what year it was when i picked it up for a buddy a few years ago..he went to jail after he totaled this thing and told me to pick up a few things at his house he was renting and just keep them for myself since he owed me a bunch of money before the landlord sent them to the dump...
The first picture is when i went and picked it up for him..second is how it is now..frame is all twisted up and plastics are fubarred..going to sell the rims and tires.they stick out way too wide on my Big Bear
