[QUOTE="oexing, post: 105180, member: 1493"] So I had a close look at what a different first tooth height will do to the jamming problem. I reduced the tooth in a few steps but this did not totally prevent the jamming. Seems the top on top tooth situation can happen at all sizes. I came to my conclusion that the best and safest way to get only very rarely any jamming condition is to modify all teeth on the small gear for very pointy tops and same goes for the first one or two teeth on the quadrant. As you can see in my Youtube clip below you have to very carefully set the pair of gears so they do meet head on head but this should be a rare case. I searched my stock of kickstart sets from various other types and most of them do have the pointy teeth that prevent blocked gears when working with same pointy first tooth on the quadrant. In the photo you see a new gear from the Spares Co. next to my reworked "pointy" gear, a carbide burr in the Dremel and diamond file did it last night. My old quadrant will get some welding at the first tooth for the pointy shape so this should do like in the video hopefully. Great to have this forum as I did not think about this matter before but when checking my Argentinian box of parts I could see that there is a job waiting before problems only show after bringing the bikes on the road.
