M-8 Big Bore Cylinders; Heavy
Duty Axle and Adjuster Kits
PARTS AND ACCESSORIES
Hitting the 'sweet spot' for M-8 upgrades, Twin
Power has added 4.25" Big Bore cylinders for
M-8 models to its product line - factory fitted for the
popular Wiseco Black Edition pistons.
When combined with Twin Power gaskets, a 107
cubic inch engine can be converted to 124 cubic
inches, and a 114 cubic inch to 128 cubic inches. This
is strictly a bolt-on kit, as the special gaskets
eliminate the need to weld or otherwise modify oil
and water passages.
Machining of the crankcase is not required either.
Gasket kits are available with either .030" or .040"
thick head gaskets, based on the builder's
preference.
The cylinders are offered in a factory style black
textured powder-coat finish with highlighted fins.
Cast-in iron liners ensure strength, durability and
quiet operation. Cylinders are sold in pairs and
include cylinder head dowels.
"The M-8 has shown incredible performance
potential, and this kit really wakes up the stock
engine," says James Simonelli, Twin Power Brand
Manager. "On a 107" Dresser with no headwork,
TTS 250 cam and valve springs, 62 mm throttle body,
a performance intake and 2:1 exhaust, we achieved
139.63 hp and a whopping 142.65 ft. lbs. of torque
with a tabletop flat torque curve."
Twin Power has also added these new heavy-duty
axle and adjuster kits for 2002 and later Dresser
models, including 2019 M-8.
Featuring a solid stainless steel axle machined from
316 material that will not rust or seize to the wheel
bearings, the adjusters are hard chromed steel with
4140 steel adjuster screws. All additional hardware
is Grade 8 and installation tools and instructions are
included.
"The high-performance Bagger scene is exploding,"
says James. "Large displacement engines, turbos and
superchargers are becoming the norm. These mods
will easily overwhelm the stock belt drive and snail
cam style adjusters, and typically also require a chain
drive conversion kit.
"In addition to the extra strength, these kits also
allow a greater range of axle adjustment and are a

perfect addition to our popular cush drive chain
conversion kits. They are also priced more reasonably
than many of the other kits on the market, but give
you the quality that you've come to expect from Twin
Power".
Kits are 100% USA made and simple to install with
only a minor spotting and drilling modification
required.
Also seen here, these new Twin Power replacement
fuel pump kits feature all the components
necessary to rebuild the O.E.M. fuel pump module,
including pump, filter, hoses, clamps and wiring
harness as needed.
James Simonelli explains: "Ethanol fuel blends can
really wreak havoc on American V-twin fuel systems.
Extended periods of storage further compound this
problem. These kits give you everything you need to
correct these problems and offer a competitively
priced solution to factory components (which in
some cases are obsolete)."
The kits are available for all 1995-2017 factory fuel
injected H-D models, come ready for plug-and-play
installation and feature a Limited Lifetime Warranty.
