Bigger sometimes is better and the formula to prove this statement is: more torque + more horsepower = more performance. Available for the Directly from Milwaukee come these 3-7/8” Big Bore cylinders which, combined with a few more components, offer significantly more pull off the start than the standard equipment. Displacement is increased from 88 cui. (1450cc) to 95 cui. (1550cc) which results in torque and horsepower gains across the entire usable engine-speed range.

The Screamin´Eagle team did an excellent job in developping a product which is mainly street-oriented rather than for the race track. The chart shows clearly where the ponies are gallopping and that added potential is at command from very low rpm´s. Another advantage is the fact that the stock cases do not have to be machined for the larger cylinders. These cylinders are finish honed for the WW# 59-790 pistons, which have to be ordered separately.
