Hey guys im a new member here, names chris and I just paid out the as* to fix my big bear 350. It got rings valve seals a rocker arm a head gasket. I got out yesterday for about an hour before it started to back fire on me and shot a huge black cloud of smoke out. I couldn't get it started so my buddy towed me back to the pick up point and after about an hour of sitting it started up like it was no issue at all. I got my beast back yesterday and have all weekend to get into it. Anything would be great thank you! Note a slight cloud to the left of the photo. Couldn't get one of the thicker smoke

      Greetings to all.  New to the forum, but not to ATVing.  I started when they only had 3 wheels!  Getting back into riding.  Polaris 850.  Too many bells and whistles, but what do you do.  Scouting out places to ride legally now.

      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!
