    4RT valve clearance check

    Decided to check the valves on my 4RT today and haven't done it on this before but have on previous bikes.
    All 4 valves were tight, couldn't get the feeler gauges under any of them so set it to TDC (checked Pistons was at top too) set the crank on the mark and slackened the adjusters, wound the tappet out reset to correct clearance then put all back together.
    When I tried to start it it now has massive compression, it will turn over and can't hear anything untoward but doesn't want to start and the compression just feels wrong, so gave up for the day and to think.
    I must be missing something very obvious but any one any suggestions?

    Are you sure you had it on the right stroke?

    Have you got the manual?

    Turn it through one revolution of the crank,so cam lobes are facing away from adjusters.
