Hi,
Just come to the point again where I need to check the adjustment on the exhaust valve lifter on my 1967 B44R and as always, I'm concerned if I've got it adjusted correctly. The Workshop Manual says it's important not to have it too tight as this could lead to a lack of power and could eventually burn out the exhaust valve, you should leave enough play when the lever's operated so that the valve can return fully when released. It says it should be correctly adjusted so that "resistance isn't felt until the lever has moved a little but I wonder if anyone has any more sound advice to enable me to be sure it's adjusted correctly?
Hello...my bike looks like yours!
My valve lifter works with hardly any free movement....try bringing it up to compression and stand on the kick start. Then pull the de-compressor.
Doing this with mine, no movement in the kick start until the de-compressor is pulled in.
Translating what the manual says makes sense...you need to ensure it isn't lifting the valve off the seat with the lever off...check that you have valve clearance at tdc.
BTW, how long is your prop stand? Does it have a sticky out bit so you can get your toe on it?
This service bulletin might help explain cable adjustment.
Thanks for the response guys.
Managed to set it up fine. Stuck at it and adjusted the spring tension using the compression kick stoke. Set it so that it just released compression at the top of the compression stroke on the kick start when the lever was almost at the end of its travel and then tightened the little lock nut.
It works great and what a feature. No more kicking back, no more firing whilst the kick start is stationary. Kick up to the compression stroke. Operate the exhaust lever and lower the kick start to half way down. Release the lever. Kick her into life! Sorted.
