helpful.. The highest unit loading in the usual poppet valve engine, is at
the cam/lifter junction. (Remeber the old phonograph with the needle; the
unit loading at the tip of the needle was as much as 5,000 # psi.)</FONT></DIV>

far from a YS genius. I have come across a few in my time however.....just
look for the guys with the blown off props and spinners, deadsticks and
always 're-tuning' their motor (usually in the pits). Nothing
scares me more than some peanut 'tuning' a YS at full song in the
pits!!</FONT></SPAN></DIV>

[NSRCA-discussion] YS points of interest<BR></FONT><BR>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>Hi
all,</SPAN></FONT></DIV>
<DIV><FONT size=2 face=Arial><SPAN
class=586021501-20102009></SPAN></FONT> </DIV>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>Just a little
topic diverter, for all us 'oilers'.</SPAN></FONT></DIV>
<DIV><FONT size=2 face=Arial><SPAN
class=586021501-20102009></SPAN></FONT> </DIV>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>Some background.
Generally in Aus, most people mix their own fuel as it is simply too cost
prohibitive to use pre-mix. 99.9% use the Coolpower oils. We have the three
types available; Blue (SV), Red (LV) and Purple(MV).</SPAN></FONT></DIV>
<DIV><FONT size=2 face=Arial><SPAN
class=586021501-20102009></SPAN></FONT> </DIV>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>I have just
rebuilt 3 different YS motors,all running on different oils. Nitro content is
25-30% depending on motor and application, Nitro brand is VP.
The methanol was Spectro C analysed for purity and water content (
perfect results)</SPAN></FONT></DIV>
<DIV><FONT size=2 face=Arial><SPAN
class=586021501-20102009></SPAN></FONT> </DIV>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>I have found: (
your mileage may vary <VBG>)</SPAN></FONT></DIV>
<DIV><FONT size=2 face=Arial><SPAN
class=586021501-20102009></SPAN></FONT> </DIV>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>The LV oil
produces marginally ( empirically tested) power, however significant corrosion
and wear was found in the motors using this oil. Cam was badly worn
also.</SPAN></FONT></DIV>
<DIV><FONT size=2 face=Arial><SPAN
class=586021501-20102009></SPAN></FONT> </DIV>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>The standard Blue
oil motor had by far the least wear, virtually no corrosion and only
small expected, standard wear ( liner, bearing play and ring gaps. Cam was
perfect)</SPAN></FONT></DIV>
<DIV><FONT size=2 face=Arial><SPAN
class=586021501-20102009></SPAN></FONT> </DIV>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>The MV oil, which
as expected, was somewhere in between the two.</SPAN></FONT></DIV>
<DIV><FONT size=2 face=Arial><SPAN
class=586021501-20102009></SPAN></FONT> </DIV>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>Conclusion for my
own future use:</SPAN></FONT></DIV>
<DIV><FONT size=2 face=Arial><SPAN
class=586021501-20102009></SPAN></FONT> </DIV>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>I will cease to
use the Heli oil in my motors as of now, unless I need to milk a motor for
every last bit of power OR if I am happy to rebuild more
often.</SPAN></FONT></DIV>
<DIV><FONT size=2 face=Arial><SPAN
class=586021501-20102009></SPAN></FONT> </DIV>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>The MV does seem
like a good compromise, but I'm happy with the Blue oil. Its the original, and
in my opinion only, still the best general performing oils of
all.</SPAN></FONT></DIV>
<DIV><FONT size=2 face=Arial><SPAN
class=586021501-20102009></SPAN></FONT> </DIV>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>Also-IF any of you
are actually still using the YS, here are a few other tips. I have two brand
new 170's-one CDI and one Glow. Both motors had virtually NO oil in the cam
area out of the box. I would recommend that you open the cam cover and squirt
it full of oil before you start these for the first time. I feel it helps and
may just prevent undue cam wear.</SPAN></FONT></DIV>
<DIV><FONT size=2 face=Arial><SPAN
class=586021501-20102009></SPAN></FONT> </DIV>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>I always strip,
rework and Ultra sonically clean my motors before I run them-so I do this
anyway, but for those that don't want to go to these extents-The oiling of the
cam is easily done.</SPAN></FONT></DIV>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>Another little
tip-lap the valves in. I just use one of those eraser tipped pencils, cyno'd
to the valve, and then spin the pencil with some fine valve grinding paste on
the seat. This works a treat, every time.( obviously, disassemble the head
first)</SPAN></FONT></DIV>

class=586021501-20102009></SPAN></FONT> </DIV>
<DIV><FONT size=2 face=Arial><SPAN class=586021501-20102009>Now feel free to
practice those snaps that we talked about ,with that little powerhouse of
an engine <G></SPAN></FONT></DIV>
