My son has a A10 and he has crook knees from multiple bike accidents over the years. He is finding it difficult to kick the bike over so asked me if lengthening the kickstart would help. Something I have never done so I'm not sure just what if any difference it would make. We are thinking about a 3" or maybe 4" longer kickstart. So my question is has anyone done this and if so did it make any difference ? Electric start is not a consideration, selling the bike and buying something with a electric start is a possibility.
