Heading into my ninth decade and recovering from two new knees, I been off the bikes for over a year. I thought I'd start small so dug out my tiger cub to help build up the leg strength again. I can't even kick the cub over. Tried the usual tricks, thicker head gasket and longer kickstart but still no joy. Other than drilling a hole in piston, I was wondering if retarding the valve timing one tooth might reduce the peak compression allowing me to get it over. I realise performance may suffer but hopfully it will only be temporary until my strength is back. Do members think it's worth a try ?
