balanced or unbalanced engines.

I'm not complaining, I find the engine vibration is just fine in Bugs. But
would it be better if you get a balanced and counter weighted crankshaft.
For engine life and less vibration. If you're going to rebuild one.

I think that is mainly for racing.

Developed by Gene Berg and Bob Dixon in 1972
Why a counterweight crankshaft? The VW air-cooled engine is designed
for low RPM, low power output and high mileage use. When used that way
it gives many years of trouble free service with little or no wear.
However, the higher the RPM, power, or the quicker the acceleration,
the more the centrifugal force bends the crank at the center main.
This bending force occurs because the two center rod journals are on
the same side, putting all the weighted forces on one side of the
crankshaft. This pounds out the case at the center main saddle, plus
makes the pulley and flywheel run out, often damaging the case at the
pulley end. It also puts the rod into an acute angle, one of the
things which drives wrist pin keepers out of the piston. If this
bending gets too bad it can cause rod breakage or even the loss of a
flywheel. Berg counterweights balance this effect so the crank not
only stays straight, it also rotates on a film of oil, as it should.
Crankshaft strength is also increased with the addition of the
counterweight. This provides longer case, rod, piston, cylinder, and
bearing life.

The best thing to do for a stock T1 engine is to balance the stock
assembly, read some of the late Bob Hoovers writings, he was the most
correct and anal person I know of without something to sell.
Gene Berg still is considerer a "God" by some today, but proven very, very
wrong many times .

Try to get hold of a copy of "The Sermons" by Bob Hoover, I have the
original release on a Cd, Most of his writings should be available through
search engines or Google groups. Find RAMWA on Google groups and do a
search..

Holy crap I found the Tulz series and it printed. Thank you.

I don't know why. I want to leave it that way to avoid spammers.
