Hi Brucie64, I have had 2 A10 motors done by SRM, I live in California, no needless to say it was even more pricey. One motor was done in '96 and the other in 2001, I completely voluntarily, bought into the idea that I had to have it done. I won't go into the details of various issues I later had with SRM, but as hindsight is 20/20, I wouldn't do it again. However this is because, since the 1st motor done in '96, has done 11,000 miles, I don't ride enough miles to have warranted the conversion, especially as I change oil about every 400miles. So if you just ride on weekends and sunny days, a standard careful, rebuild, using a reputable machinist and quality parts, is perfectly adequate, and if done correctly and the oil is changed regularly, you should get 50,000+ . I do however suscribe to some of the newer improvements to ignition, and carbs.
Good luck with your decision.
