Hi There, last week I had a great run out to the Highlands of Scotland on my Classic 500 and it went like a dream as usual. However, next morning she struggled to start and once she did she was spluttering like hell and finally stalled and has refused to start again. On inspection I found compression gone and that both valves were slightly open. The rockers were tight on the valves holding them down at top dead centre. I loosened off the rocker bolts and compression returned and valves re-seated. Anyone any idea why this would happen?? I have now stripped her down and am trying my hardest to get the pins out in the crank area that hold the lifters but they seem solid. If anyone has any information or knows what has happened here it would be greatly appreciated. Thanks
