It started out fine, but......

Ended with poorly Norton ES2.

Heading out out to Hagworthingham to meet the Poachers for a Sunday ride out and I lose compression just outside Wragby.

Onto the phone and MrsG comes with the van and takes me home.

Off with the head and it's a stuck exhaust valve, which has also made a nice clearance for itself on the piston.

Seems I've got a little work to do.

After checking the piston, its o.k. The exhaust valve and guide are changed and seat recut and we're back in business.

Pick up in the guide

Corresponding pick up marks on the valve stem
