wtb: 1925 JD rear cylinder

[knucklehead 61]

I took my 25JDCB for a ride yesterday & blew the top off the rear cylinder.
So now I am looking for a good used 74" rear cylinder to replace it.
Any leads appreciated.

I probably have what you need. Send me a private message and let me know here that you did. I'm in NorCal.

Any idea why it blew?

My guess if you took the time to analyze it that one of 3 things caused the cylinder to blow.

1. Timing off.
2. Intake leak.
3. Overbored cylinders.

Overbored without proper stress plates.

No, it was bored and sleeved which leaves a sharp ridge at the time in a blind hole thus a fracture zone. Another cylinder is taking it's place.
