>My two kick start ones, well they get through chains and front sprockets fast
Risking asking a stupid question, you know the cush-drive is crap? 'Back in the day', the usual mod. was to swap in the rear wheel of an electric-start one, that had a better cush-drive. I used to fit 5/8" x 3/8" chain 'n' sprox, which were widely-available in the Smoke when lots of RS's were used by dispatchers.
