[QUOTE="oexing, post: 105404, member: 1493"] No matter what you do to the first gear tooth on the quadrant, it will jam with a shape that is not pointy. As I showed in my posting above, I had reduced tooth height in several steps but no joy. I could still find situations when gears jammed top to top. The ONLY way to minimise a likely hood of jamming is to sharpen the first gear, filed or not, on the quadrant, to a pointy shape so in operation you will have to position its top EXACTLY to meet one pointy tooth top of the kickstart gear. Both components pointy you will be challenged to jam them as shown in my video clip above . The MPH photo really only confirms the pointy shape idea, polishing any sloping areas may be nice but not essential. The real trick is to have the top point stoned smooth so it will rather slip in any direction than jam. Please test your ideas on your bikes by carefully trying to find a position of jamming, the wider any face on gear tops is , the easier you will get a jam. The kickstart gear has wide tooth tops which is design flaw really. This has to be corrected with next production, basically. But I will not tell them at Spares Co myself, seems they won´t listen to the people, matter of pride maybe. Vic [/QUOTE]
