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?

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!

quad is a new to me freebie, pulled carb and cleaned it. got it running and idling nice but mid throttle it craps out and will go down to almost a stall, i release throttle and it just sits there idling away happy as a pig in poop. i was thinking fuel restriction then i noticed the exhaust glowing red in the sunlight. so its running lean

bottom of the tail pipe was rusted out and the little nut also ripped off when i tried to undo it.
a 540 ml soup can is the same id as the exhaust pipe od and the soup can has ridges to make it a tight fit
a little bit of a mickey mouse fix but it works
