Ah c'mon, you gotta change the exhaust, you must have what, 6 months on the old one j/k

 

Yeah, it's about 6 months on it............LOL

It's a keeper.............took 9 tries but I finally found the best one of the bunch.

Steve

 

I don't know Steve, I hear from the rumor mill that TW has come out with a matching exhaust for the TW6 [sm=confused06.gif]so with that said I think I can take that used D&D off you for a very small fee.[sm=icon_rofl.gif]

 

Has anyone used these lifters -

Or how about these -

Cams showed up today, bearings arrived today, now all I need is gaskets, baisley spring, and lifters..........and the cam area will be good to go for the swap.


Steve

 

I heard bad things about the mad dog guy on ebay. Don't know if it is the same place or not. They are pretty much all the small block chevy lifters anyhow. Give one of them a shot and see how they work.

 

I hate to be the guinea pig.........I'd rather use something people have used with good success.

I wanted the other ones for $50, but he won't be able to ship anything for a couple of weeks.

The Falcon ones look good.............would just like some feedback.


Also looking at the Cometic top-end gasket sets...........want to make sure I order the right one of those too.

Steve

 

Cometic #C9844 is the top end kit with .030 head gasket for 1550 engines.

 

Hey Steve I've heard good things about these lifter's got a set in a box with my cams I haven't installed yet

[align=center]AMS Johnson-Hylift Lifters
for all Twin Cam Harley engines[/align][/align][/blockquote]
[/align][blockquote]
From 1999 - 2001, Johnson-Hyliftsupplied 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 an air-cooled engine such as the Harley.Since late 2001, HD has used
Delphi brandhydraulic lifters. That's why there was a Harley p/n change
from 18538-99 to 18538-99A and now 18538-99B. However, Delphi did not
use a 0.655" hi-volume / hi-pressure plunger piston andvalve body
specifically designed for Harley as found inthe Johnson-Hylift lifters.
Instead, Delphiessentially used asmall block Chevy lifter. The main
difference is the Delphi lifter tries to boost the hydraulic psi by decreasing
the piston diameter, but this leads to a smaller high pressure oil reservoir.
The volume is too small and allows the lifter to clatter. That may be why
so many of the late model Twin-Cam bikes are noisy.After doing some
research AMS learned these Delphi version 18538-99B liftersare made too
small to stand up toHarley's heavy valve spring pressure. The oil reservoir
inside the lifter is too small. It doesn't hold enough oil to let the lifter bleed
off under normal use and still have a cushion of compressed oil to take up
valve train slack. Note: ALL lifters bleed off during operation and even
more-so when the bikes sits, engine off.

AMS went back to Johnson-Hylift's Chuck Hicks, the original
manufacturer / engineer of the earlier HD 18538-99 lifters, which
don't seem to be as noisy as those made by Delphi. Working with Chuck,
AMSmodified a Johnson-Hylift lifter,to accept a very precise check valve
from an A900 Ford Mustang lifter. Then we usedalarge 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. What
this does is give us a 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 ball seat
ensures better top-end rocker oiling and better pushrod tip fit.... all of
which makes for a quieter lifter.

Our p/n for these AMS Hylift lifters is LIF2148. We recommend using stock
non-adjustable pushrods with them... howeveradjustable pushrods will work
too- but it does require getting the preload set within the .080" to .100" range.

There are a dozen 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, etc. However if you're convinced you've eliminate all of
these things, and the liftersstill rattle, then the next step is to try another set
of lifters, preferably the AMS LIF2148's with their larger oil reservoirs. Many
times this will lessen or eliminate the noise. For more info and a special
discounted price quote on the LIF2148, give us a call at 1-800-210-8675.

I might just go with the Falcons and give them a try for $40.

Zannottis has the "b" lifters for $20 each.

I say go for it. If it is too noisy or you have an early failure then you didn't lose too much
