Determined rear cylinder exhaust valve spring broke and caused my breakdown. 28,155 miles on it after the build. Pictures in thread on its motor in M8 section. Also rode the CVO King to club house fo meeting.
Dave, that sucks! BUT you have a bunch of miles on that build.
I passed on the ESP figuring I could fix whatever happens on my build with that money and rolling the dice that the motor lasts.
When I upgraded the motor and addressed the clutch issues all was good UNTIL my trans failed after about 8k miles on the build. I don’t hammer on my bikes but I do use the power! I “babied” third gear roll ons figuring that is one of the weak links in the stock transmission. Sixth gear dogs and shift forks were the issue. Seems sloppy fitting gears and assorted parts are to blame.
Baker grudge box builder kit on the way! LOL
I’m not looking forward to updating the primary and rear drive, but we’ll see.
Good luck getting yours back on the road!
