If your riding habits lean to road riding your ATV during the

summer, chances are you do the same thing in the winter too. I won't go into the legal or ethical ramifications of running an "off-road only" vehicle on the highways, however I will address the mechanical ramifications. Obvious road salt damage shows up on frames, chains, aluminum rims and engine cases.
Damage that isn't readily apparent occurs to your exhaust system. Sometimes the headpipe is rusted into the exhaust port and only shaking or prying the headpipe will remove it. However, this prying or wiggling is not the best treatment for a severely corroded exhaust because, as with this particular pipe, the right pipe split lengthwise. Why did it split? The pipe's walls were corroded paper thin. Welding was an exercise in chasing holes.

To close the split in the right pipe in preparation for welding, it was bolted into a spare head that was secured in a vice. The collector was bent to close the gap then the welding began. And about the same time, the corroded joint between the left headpipe and it's flange broke completely away! The official HMCA position at this point was"Take this rusted piece of crap out of here!" No amount of work will ever make it good again. If you dare touch the welds to clean then up visually, the paper thin walls will give away again. Just pop $100 for a new factory headpipe (Yes, 350X headpipes cost that much!). What about welding it up the best way possible and continue to run it? Check out the condition of those clamps that slide over exhaust studs! They are almost rusted away too! Also note the right pipe flange that required welding back on.
And how do you prevent this from happening? Either stay off the salted roads (although some kids only demonstrate enough riding skill to hold the throttle wide open down the middle of a highway) or hose off the machine to remove the damaging effects of sand and salt.
