#5: Re: Virago xv250 Valve Clearance
Adjustment. Author: j0n24, Posted: Sun Mar 01, 2009

Well I successfully
checked/adjusted my valve clearances this weekend. Next time, I'm sure it
won't take me half as long. I removed the seat, battery, fuel tank (didn't
spill more than a few drops of gas despite having a full tank), air filter
pod and thermo switch housing (left pod). The rear cylinder exhaust valve
is quite a tight fit, but I managed (hence removing the battery).
I used the Cyclepedia online manual to assist with the job, but I
have to say the most difficult part was trying to find the TDC on the
compression stroke for the intake valve. What I failed to realize is when
all manuals say "turn the crankshaft around until you see the intake valve
close and then rotate the engine again until you the appropriate TDC
marking matches up etc", they mean that a closed valve is actually up. So
the rocker arm is in the up position. I was initially reading into it that
a closed valve was seated down into the engine not up, and as a result I
was not on the TDC of the compression stroke, resulting in the appearance
that all my valves were way to tight!!! Anyway, a lesson learned.
I'm going to contact the Cyclepedia people and let them know that
a little more clarity should be provided regarding valve clearance
adjustment, given that the intended audience are people who require a
little more hand-holding than those who just use the service manual.
Thanks for your help!
