Top end of the engine is easy if you take your time, I just got done with my 750's. The bottom end is pretty rock solid unless you really ruin something. What kind of lower end problems are you having?
Not exactly sure what his main issue is.
All I know is that the electric starter can
BARELY turn the thing over, and it feels like a 15:1 V-Twin when you try and kick it over. So me and Cursed are guessing it spun a bearing or something. All pistons are still moving (we can see thru the spark plug holes), but for whatever reason the thing is def. not free (not totally locked up either)...
