    78 Sierra Trail Boss

    This past weekend I bought this little AATV.

    For what I paid for it you can't buy the motor new or used.
    Doesn't look to bad body in good shape with very little scratching.
    Tire appear to be original lots of tread on the lugs and plenty of weather cracks but are all holding air.
    Very little rust on the frame and chains.
    Chains all look good with no slop and don't look stretched.
    Guy who sold it couldn't get it to run took me about an hr but I got it going barely before buying to check if the tranies worked.
    A previous owner swapped out the 2 stroke with a 20 hp Vangaurd.
    Once I got it home put new plugs in it, fresh fuel and fuel filter and it fired right away.
    This thing is pretty quick now the 2 trans need to get adjusted as the left stick moves about 8" and the right about 3".
    I've spent the last cple days reading the posts on this site on these machines so I know how to set them now.
    Will be doing a fluid change as well on the tranies and the motor and then tackle a fairly messed up wiring harness.

    I do have a cple of dumb questions.
    On the bottom right at the back on both sides are holes about 7/16 in the body extentions where the frame sits.
    I know they are drain holes just not sure why.
    Are they there from the factory or did someone add them at some point.
    I know from yrs of boating we would pull the drain plug while in the water and moving to get rid of the water in the boat.
    As most of the time you would be moving through the water they would allow splashed water to escape and once out of the water would allow water to drain out to help prevent rot to the frame.
    Considering how much design work went into making these things water tight then why an open hole that is this small that can and were plugged up with garbage on this one.
    I don't know if I could find a locking plug this small to put in them.
    As part of my plan is to gain entry into better hunting positions I'll be sitting out in water not moving that's deeper than the Trail Boss is tall for many hrs.
    Wouldn't a screw in brass or plastic drain plug into a brass bung have been a better plan.
    Any how it'll be something I'll be addressing before hunting season, will see what my local boat place has that could be used.

    2nd question is as this thing is a redish orange color.
    From what I've seen on this site and others I believe they all were built in this color.
    Would painting it camo colors hurt it's collector value if there are collectors out there.

    I'm sure there will be more important questions in the future as I get into repairs and fixes on this new project.

    Here's a cple pics
    the fan on the back deck was added by the seller as he felt the exhaust heat was to too high inside the body.
