Let get all the facts then, the rear bearing for the 140RX is also used in the FT160 nd FF320. I have three of these beast, (140RX)changing the bearing once a year ain't a big deal....takes about 1 hour...remember one thing this is a high performance engine and that do mean TLC, feed it good, run it dry, and store in a dry area.....garages by he way are not a dry area(depending were you live!
