After finally getting a spark, changing the cylinder rings & gaskets & rebuilding the carb, I thought I was going to get my 1977 V1 to turn over (according to the previous owner it had laid dormant for 20 yrs). However, notwithstanding my efforts to save this classic bike from the heap, the motor won't turn over. The newest problem is when I hold the clutch in & crank it seems like there isn't enough power from the starter clutch to turn the fly wheel - at first I thought the spindle key was worn, but it wasn't - I also tried adjusting the clutch cable - no avail. Has anybody had this problem or know what it is & what I'm looking at in time & money to repair it. Many thanks.
