Title: valve spring length 400/4
Post by: Fogdevil on June 07, 2016, 01:01:03 PM

Hello everyone
Measured the inner and outer valve spring lengths.
All greater than the minimum length advised by mr Honda but only by about 1-1.5mm on all springs.
I don't intend to delve into the bowels again for a long time so would it be better to get new springs?
What is the length of NEW inner and outer springs?
Thanks in anticipation
Fogdevil
PS Struggling to send photos as I can't compress the photo enough

These are the figures from the CB350/400F Shop manual (to be found in Ashimoto's dropbox http://www.sohc.co.uk/index.php/topic,8884.0.html).
Same figures for both 350F and 400F.
