If you have ever noticed your clutch slipping when you are driving, it is usually due to having deep scratches in the flywheel that hinder the normal operation of the clutch and the flywheel. Small things, such as slips or jolts when shifting, are usually the first sign that you need to balance your flywheel.

The illustration to the right, shows Darkhorse Crankworks' corrected and dynamically balanced flywheel. Each individual part has been balanced using the exact same ratios, which moves center of gravity in parallel with flywheel center and the sums of all parts are then
dynamically balanced. We do not use the automotive method, (spinning at 500-750RPM) that is reconfigured and loosely adapted to achieve balance in your crankshaft. At Darkhorse, our procedure insures that each flywheel is balanced to
