AMS hi-performance Ported Cylinder Heads for TWIN CAM engines.

(CHVHD88) Ported Cylinder Heads $578.00 Exch.

Our heads are thoroughly cleaned and inspected, then machined to exacting
specs. We form the valve seats with a state-of-the-art SERDI Machine
to our unique multi-angle shape. Combined with our specially machined
valves, the multi-angled seats perform with maximum efficiency and
reliability. Our heads are CNC and/or custom hand ported and flow tested
to enhance both torque and power in the valve lift and rpm ranges most
commonly suited for use with the best performing street cams. We also
coat the exhaust ports with a ceramic-metallic thermal barrier to reduce
both head and oil temps, as well as enhance the exhaust gas flow
velocity. Finally, our heads are assembled with hi-temp resistant Viton
stem seals, valve seating pressure is tested, and valve closure/sealing
is vacuum tested. We strive to deliver the highest quality heads in the
industry - and back them up with our "No Hassle 12 month Warranty".
Sold as a set for as low as $599 exchange or if you prefer to keep and use
your bike's original heads, we can perform our "magic" on them in
about 5 days for the same price.

AMS hi-performance 96" and 105" Big Bore Piston and Cylinder Kit.

AMS hi-performance 96
The 96" kits fit 1999-2006 TWIN CAM engines with stock 4" strokes.

The 105" kits fit 2007 and later engines, as well as older engines with
a 4-3/8" stroke.

Our big bore cylinders are bored and honed using JIMS torque plates to ensure
a "round" bore. Unlike many shops that simply hone them out, our cylinders are
precision bored using either a Kwik-Way air-centered boring machine or our new
5 axis CNC milling machine. We take the time to bore them in three stages to
reduce both heat and micro-fracturing of the metal. The cylinders are then honed,
using a three stage process to reduce heat and produce round, precisely
dimensioned bore. We also put a plateau honed finish on them to help reduce
break-in time. Each cylinder is bored to match the piston to be used, giving our
Big Bores a custom fit for maximum performance. Our Big Bore Kits use "high
quality, precision made" KB Pistons and Hastings piston rings or specially
designed, lightweight, offset pin Forged pistons. KB's hypereutectic alloy is
stronger and lighter than the factory's cast aluminum pistons, reflects heat much
better - keeping the heat energy in the combustion chamber where it can be used
for power instead of raising the engine oil temp. And the Forged 2618 alloy pistons
provide much needed strength for the longer stroke models, with reduced piston
slap for a quieter and longer lasting engine. Being lighter means they can rev
higher and accelerate faster, with less stress on the crank and rods than stock
pistons. The AMS Big Bore Kit comes complete with two cylinders, two
custom matched pistons with rings, precision hardened wrist pins and lock clips.
Throw in our 12 month no hassle warranty and excellent customer service and
you get a whole bunch of Bang for your Buck!

(96BB) Big Bore Piston and Cylinder Kit $389.00 Exch.
(105BB) Big Bore Piston and Cylinder Kit $479.00 Exch.

We also offer Cometic and CYCO Gaskets, K&N filters, D&D EXHAUST Systems,
AMS-HYLIFT and Crane lifters, ANDREWS CAMS, PEP guides and valves, S&S
cams and gears, and most other brand name parts for your Harley-Davidson

purchase - we will try to meet or beat the competition's prices.

AMS Johnson-Hylift Lifters for all Twin Cam Harley engines

From 1999 - 2001, Johnson-Hylift supplied lifters to Harley-Davidson...
Johnson-Hylift designed and produced a special piston and valve body
to work across the temp ranges and varying oil psi typically encountered
on a Harley engine. Since 2001, in a cost-savings move, HD has used
Delphi hydraulic lifters, which explains Harley's p/n change from
18538-99 to 18538-99A, and after some problems, a second Delphi lifter
was used, p/n 18538-99B. However, Delphi still did not use a 0.655"
hi-volume / hi-pressure plunger and valve body like those specifically
designed for Harley by Johnson-Hylift. After some research AMS learned
Delphi 18538-99B lifters bleed down rather quickly due to the
higher engine temps and heavy valve spring pressure found on most
Harley Twin Cam's. The oil reservoir inside the lifter is too small,
allowing the lifter to clatter, and likely causes many Twin-Cam bikes
to be noisy. Note: ALL lifters bleed off during operation and even
more-so when the bikes sits, engine off.

Tom at AMS has known Chet Starron, who owns Johnson-Hylift, for many
years. Chet put Tom in touch with the original engineer of the earlier HD
18538-99 lifters, which don't seem to be as noisy as those made by Delphi.
Working with Hylift' engineering staff, AMS modified a Johnson-Hylift lifter,
to accept a very precise check valve, a larger plunger that allows more oil
reservoir volume, and a ball seat that fits much tighter, yet has an oil feed
groove to allow more upper rocker box oiling. The result was a significantly
improved lifter, with a much bigger internal oil reservoir that will keep the
lifter/pushrod from bleeding too much and bottoming out. The bigger
reservoir maintains a cushion of oil inside. The improved ball seat ensures
better top-end rocker oiling and better pushrod tip fit.... all of which makes
for a quieter lifter.

AMS and Hylift have continued to develop this lifter, and today, we offer
3 versions of the AMS-Hylift lifter for Harley Twin Cam applications:

AMS A2313S for stock and performance street bikes. $29.95 each

AMS A2313R for all out, hi-rev racing applications. call for quote

AMS A2313-002 this is a 0.002" oversized version of the AMS2313, for use
in cases with worn lifter bores. call for quote

We recommend using Andrews adjust pushrods, or stock non-adjustable
pushrods with them... however other brand adjustable pushrods will work
too. These lifters have a wide preload range, which makes for easy
installation if adjustable push rods are used.

There are many other things that can cause "lifter" noise - it can be coil
bind, rocker to spring cap interference, spring cap to stems / guide length
interference, poor oiling, high lift cam profile causing loft, overheating motor,
wrong oil viscosity for ambient temperatures, aerated oil, low oil pressure,
gear drive backlash, worn drive chains, etc. However if you're convinced
you've eliminate all of these things, and the lifters still rattle, then the next
step is to a set AMS-Hylift Lifters. With their larger oil reservoirs, they will
usually lessen or eliminate the noise.
