<DIV><FONT face=Arial size=2>Verne: Based on my experience with
the YS .60 & .61 two strokes,the grease will disappear very soon,even with
two seals intact. </FONT></DIV>
<DIV><FONT face=Arial size=2>I don't think lubrication is the problem,or the
cure. The rear bearing is just too small.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It seems this size bearing started out in life as
the bearing for the 1.08. It makes no sense to me that a bearing
for a rather mild 1.08 would stand up to the rigors of a 1.40.</FONT></DIV>

<DIV><BR></DIV>
<DIV><FONT size=4>Anybody out there try running the O.S. 1.4RX rear bearing
with the shields intact? It seems to me that the design doesn't allow enough
oil to get to the bearing. Keeping the case cool would help matters but I'm
not sure it's the total or only solution to the bearing life problems. Seems
like I read where the EFI version uses a stainless bearing with seals. If
so, they'd obviously have to be packed with grease like the front bearing
and from what I've read on this list, the front bearing never seems to wear
out. Granted, it doesn't take the pounding experienced by the rear bearing,
but it should be getting very nearly as hot. Maybe the trick is using a
sealed bearing packed with grease? I'm going to give it a try and I'll
keep ya posted.</FONT></DIV>
