timing conundrum
Posted: Thu Feb 04, 2021 4:50 pm
Hi Chaps,
Cracked fibre timing gear replaced with a nice brand new metal one, checked timing marks on the old one and the haynes manual, 7 teeth between the 2 markers, and yet the only way the bike becomes a first kick starter is to remove one timing backing plate screw and advance beyond what is normally within range, then it fires up a treat and runs beautifully. Within normal range i cant get it to start at all!
I', tempted to advance the timing gear another tooth to move the trigger point into the normal range. the motoplat rotor is in perfect shape no damage, and all timing marks in the valve train are correct, triple checked those.
Has anyone else had this issue, it's a late 1975 350 with motoplat ignition. I haven't used a timing disc on the crank yet but will borrow one tomorrow to check with that.
