Camshaft description BW 55 2007 and up-Chain Drive Gear Drive is special order
These Chain Drive Cams where in the 2012 Buffalo Chip Bike Build along with Terry Components. This cams has nice power thru the range with out a lot of the extras needed( head work- high compression) for the ones who want to save money. BW-55 cams where very friendly with Terry Components EFI interface. Keith Terry was very pleased with the results and the way the engine performed as this profile was designed for the 96" engine - Making 90+ HP /105Tq
These same cams in a stock 103 with pipe 95+Hp & 110+ Tq After Tuning
WHAT IS OVERLAP ?
These cams get from .004" to .053" in only 32 degrees as our competitors cams get only from .020" to .053" in 36 degrees the result is better manifold vacuum, do to less non-advertised overlap also referred to By HARVEY J. CRANE as the cross over area so better engine acceleration thru the range.
The BW-55 for 96" BW-47 & 44-For the larger cubic inch engines and or higher compression.
BW-62 designs are of the same ramp up design for those who have ported heads
with added on big bore cylinders and compression.
Quicker ramp up means a Great cam for big bike and even the lighter ones.
