    1100 raider sank

    My raider sank this past weekend and now I'm having one heck of a time to get it to fire. My questions are. Is there an easy way to get all the water out of the case. I've pulled the head and noticed that the piston tops have numbers stamped into them. Is this normal. They are different numbers. Two have 25 one has 50. Does this mean that the cylinders have been bored and they are 25 + 50 over. Also I'm wanting to check compression. What is the plug thread pitch and what am I looking for as far a compression

    a compression tester from the auto store will work
    also yea i think someone used two .25 over and one .5...probably did more damage to one cylinder and had to bore it a bit more, if your going to redo it, i would say go 1 over for all of them so they are matching.

    I had a friend of mine sink his and we had to pull it all apart you will have to drain the tank go through the carbs pull the stator cover to get all the water out if it was running good before just leave it the same unless you just want to bore out the cylenders. Oh and check your eletrical box for water

    Finally got her running. Took three nights, three sets of plugs, and two batteries but I got her running and better then before she sank. Ended up tearing it down and putting it back together as it was except carbs were a little off. Compression is even good
