Unusual,
Look for a broken valve spring and/or obvious signs of the valve
kissing the piston .

Also look for .....me ! If Les is willing I told him I would bring his
bike right out to him . He is in Washington state so you are right on
the way there from here in Meechagin . (see the other post real close by
)
Of course there is a chance he will have a change of heart soooo our
visit may have to wait .

Good luck and lets hope it takes more work than $$$ to get it going
again.

Hi Gary,

Road was bent at the top end. About a 1/4 of an inch from the bottom
edge of
the cup.

I will pull the head this weekend. I am thinking what you are....valve
stem
bent or broke. When I intalled the new rod the valve would acuate when
the
engine was hand turned. I tried to fire the bike up and she would run on
the
right cylinder but not the left. Seems to me that the intake valve has
shut
down.

I'll let you know what I find out...Ian

Ian tell me more about the pushrod .
You may have already , but should at least check the valve and guide .
Check the valve to make sure it is not bent . A quick - QUICK
(approximate) check is to roll the valve on the edge of a table or chuck
it up in a drill. Note that the head should show no sign of irregular
running . Even then it is best to have it checked properly at a machine
shop. The valve stem should be checked for the signs og running tight or
siezing . A sticky guide can cause an overload to bend a p-rod.
NOW for the most often overlooked mis diagnosed cause ; A blown head
gasket . The gasket blows hot gasses into the pushrod and the reduced
strength will cause the metal to yield and bend . This is most common
with Aluminum alloy pushrods . Steel pushrods are not weakened as easily
at higher temps and usually survive . Triumph twins are very susceptable
and actually break in time when the gasket leaks .
