Story time!


A few years ago a 40 something that thought it would be cool to ride an old British bike, bought his first bike ever, an absolutely stock BSA B25.  He was having trouble starting it and brought it to me for help.  It started very easily for me, but the noise coming from the primary was unbelievable.  I shut it off right away and assured him that the engine was about to go so he asked me to fix it.  Long story short, when I took the primary cover off I could see that the rotor and stator were working as the drive-side main bearing.  Once I dug deeper I could see that the drive side ball bearings were in the bottom of the crankcase.


The truly amazing part is that a new main bearing and a used stator and rotor was all it took for it to live again!
