I have a QT50 bottom end. The clutch has been removed and so has the flywheel. The entire crank, and other internals are all intact. I came by them a year or so ago and never did anything with them. The cranks and mainbearings appear to be good, the cases good...
Great back up or to build a fast motor from.
I have two bottom ends (both minus clutch and flywheel) and only want $25.00 ea for them plus shipping to where ever you are in the USA. Will only ship in the USA.
