    I love finding places like this. That's what it's all about. Bet a troll lives under that dam ...

    If you're only getting 3000 miles out of a 520, you're doing something wrong, my guess would be over tightening (since there isn't much else that would cause that kind of wear :scratch).

    Need suggestions please.

    Apparently I've got a pin hole or two right at the right tank locator. Nothing visible, some pics attempting to show.

    Used stock tanks are cheap and plentiful. There are several choices of larger capacity plastic tanks.

    Thanks. Should have said, this is on hacked DR, upper bracket under tank limits aftermarket.

    This being an rural area at least I've got plenty of JB Weld options, suggestions in that vein?

    If you are determined to fix the existing tank use a fuel tank sealer.
    IMO the best stuff comes from Eastwood but POR-15 makes some good stuff as well.
    I would not try to patch it from the outside.

    Thank you.

    Anyone got a 2000 blue stock tank for sale? First choice...

    I have been scouring the internet today- I cannot find anything about that dam.
    It has to be old and it is quite isolated from any modern day activity. There is a much larger river just over a mile away. Why build it there?
    From what I saw the brief time we were there isn't much held back from it, no lake. Water just runs over the top. Very curious.

    EDIT- I believe I found the story on that small dam and the access door- A large dam and 6.2 mile tunnel was built along the Pigeon River creating the Waterville Lake. This was finished in 1930.
    I found a 1938 map that shows the path of the tunnel- which seems to be hard to find on any modern maps.
    This tunnel, from what I can tell passes directly under the small dam we came across.
    I suspect that is some access point to the tunnel for maintenance.
    Pretty cool!

    The drop from the lake to the powerhouse is about 1000ft- I would suppose that much drop, with about 400psi, would spin the turbines quite well.
    I'm going to keep digging for info.

    Red circle is where we were

    mysterydam.JPG


    ADDITIONAL EDIT> found some more interesting info- that concrete structure is not a dam at all!

    It encases and protects a 14ft diameter steel pipe the water passes through on it's way to the powerhouse.
    The valley there, formed by Mt Sterling Creek, was deep enough they apparently did not want to go below it- so they went through it.
    Below was captured from the July 14, 1929 edition of the Knoxville Journal.
    Again red circle indicates the point we were at

    Measure discharge? Power a sawmill and the pond has silted in? Mongle's ancestors water source for distilling honey dew vine water? :ilmostro

    I must be missing something about chain construction here.

    Why does the pin wear in 2 separate, side by side grooves?

    That pin is covered by the outer roller, which is just a loose fitting sleeve, no?

    My old DR's chains in miles, all replacement chains were DID, except the 520, which I don't know what it was.
    18517 OEM
    10688 a 520
    18300
    18185
    14546 was pretty much still OK but I put a new one on because I just did the engine work on it.
    6302 currently running
    new DR
    16391.6 OEM
    5256.5 currently running
    And I sometimes oil them and even, on rare occasions, clean them!

    Many designs have two grooves on the interior ID of the roller. To “hold” lubricants

    And to be fair, chain life has a lot to do with riding “style” and abuse.
    My SV650 which I sold prior to the trip, had 237,000 miles on it. And I used to track chains and consumables on a spreadsheet too.
    Smooth riding. Smooth acceleration. Smooth braking. Proper slack. So many things affect chain life. But riding hard, allowing the chain to accept the abuse of your choices of when to shift or brake, staying on throttle over that sharp edge, cleaning when dirty, etc....all play a part and are hard to quantify

    I got one of these kits:

    from Eastwood to do my TW200 tank. It will certainly seal it, and fix any rust you might have.

    This is from the OEM chain on my Vstrom but shows how the rollers wear the pins. Back in 2001. Sorry the side plate is off the end of the pins.

    I flew RC planes for a short while (I hated building them and everyone crashes). One of the more 'frugal' flyers broke the carb off his engine. In an effort to avoid spending money on a new motor that he couldn't afford, he JB welded the carb back on. The JB weld held for the two years I was there and still running when I left.

    After seeing that, I'd use JB weld to hold the Space Shuttle together. :nod So I'd clearance whatever rubbed the hole, clean the surface and JB that beotch. Note that I'm a day rider, any failure will only inconvenience me for a day BUT dripping gasoline on a hot engine could ignite and ruin more than your day - YMMV, use at yer own risk, you din't hear it from me, nothing sticks to a plastic tank, yada yada yada. :uhoh The OP should buy a replacement tank. :deal

    I am of the mindset the chains do stretch. Reason being is that you measure from pin end to pin end. Only way that can change is if the side plates stretch. Once stretched it causes heavy load on the rollers which causes the wear you see above...and the quicker wear at the end of it's life.
