Thanks Guys, I appreciate the comments.
I didn�t get a lot of time on the weekend as I was away most of the weekend however I did get time to pull the head off and have a look inside the cylinder to check its general condition. I am confident I will be able to get the valves off without too much trouble.
Secondly I have been doing some reading about the grinding of valves. Some suggest using a hand file and some suggest using a grinder. I personally would be more comfortable using a hand file to ensure the valve end is kept square and to ensure I don�t take too much off the valve end.
Do you have any recommendations on the valve grinding method to ensure I don�t take too much off the valve end? I would like to further understand the process behind remeasuring the clearance after grinding. Will I have to completely reinstall the valves, valve springs & retainers before checking the clearance or do you have a trick for this process.
