    Wow :shock: , that's gotta suck ..,.... Yea the hole did not look that deep looking at the surrounding puddle , maybe a foot at most ........ Bet that was a big surprise :o ...Hopefully when you got it home you did a major engine flush and repacked the silencer and drained and cleaned the carb , and blew out all the connectors ..... now would be a good time to use Dielectric Grease at all connections , to help keep the moisture out , just in case you run across ...or rather into another deep puddle 8-[ .......

    He did a top end rebuild and flushed the engine with Diesel and Several times oil.
    It works like new again but it def wasn't good for the poor cr

    On a related note (trust me) he needs to take all the linkage , swingarm , wheel , steering head bearings out and clean and regrease/repack them all as well , along with something that is usually overlooked ...... Take the chain adjuster bolts out and flush out the swingarm with WD-40 , then on the swingarm side of the weld where the wheel goes , on the bottom of the swingarm , drill a 1/4" hole , so if/when the bike is in any water , the swingarm will drain ..... I don't know how many times I have seen the adjuster bolts rusted in place and end up stripping out the threads and then the swingarm becomes a project trying to get the rusted bolt out , then re-tapping the threads or having to install Heli-Coils , so put in the drain hole now , before it becomes a problem later

    Drill the hole where indicated on the underside center just behind the weld (don't drill at the weld or you will miss the inside of the swingarm and drill into the plate for the bolt , which will not allow it to drain)
