    Crankshaft trued and welded

    What does that exactly mean. What is done? I'm guessing it makes it stronger?

    BD, when the engines are built to deliver more power and they are hitting the rev limiters, they are coming in and out of the water etc. the crank is taking a beating. Some times this beating is enough to take the crank out of phase or "index", welding of the crank prevents this from happening.
    Trueing the crank basically makes sure the piston comes to TDC exactly when it's supposed to for better combustion, movement past the ports, yadda, yadda, yadda.

    So a trued and welded crank is important to have when building power. With a stock or mild application it's certainly not neccessary but it sure wouldn't hurt.

    Speaking of cranks, anyone know a great place to buy Polaris main crank bearings (not rod bearings) at a reasonable price?
