Re: How many engines
Two motorbikes - but only one Dax-purchased China Girl. Don't know how many thousand miles (I keep it as well-tuned as I can). Four years old, going on five I think. What Maniac says is largely true. Maintenance with these two-smokers is minimal, but extremely important: proper oil mix, proper jetting, clutch in good shape, well adjusted magneto, good spark plug that is gapped just right, etc. I even took the time to do port matching, got a performance air cleaner, high-end plug and wire, and other bits. She hums really nicely. Hardly any vibrations at all.
Now, I've worked on plenty of other small engines for other things. But I've only ever needed the one bike motor. I'll replace it when I have to.
