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 have replaced the cracked stator cover on my non-running 2006 LT-F400F that I purchased recently, checked all the shafts vs the service manual and pics and advice here. I replaced missing gears, bushings and washers, made sure that truth marks were all aligned properly, that the shift cam springs felt like they returned properly, etc. IAfter installing the new stator cover I checked the transfer lever for proper movement from L-H-R and then cranked it up. Happily, it runs and changes gears well in L, but it will not shift into H or R for anything. I have opened it back up and am going back through it looking for the missing puzzle piece(s) but how can I best check that I have everything right this time before buttoning it back up?

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!

Does anyone have a recommendation of a really Heavy Duty ATV cover. I have bought several and they do keep the water off somewhat, but they are very thin and do not contour with the shape very well and water pools up in the rack louvers. I think i may be looking for a heavy canvas one, if anyone has a recommendation it would be greatly appreciated.

Have you ever been on the trail and your tire valve goes bad. No way to break down the wheel and replace it. A lot of you probably know about this already i had heard of it but never used one. Just punch out the old one insert and tighten down the nut
So far it has worked very well.
