Re: Top-End Reassembly
24 Oct 2025 14:10It applies to any four stroke piston.Is the drawing adaptation below better suited for our DOHC motorcycle engine applications?
The cam configuration bears no influence.

Re: Top-End Reassembly
27 Oct 2025 13:49 - 27 Oct 2025 14:08What are you doing with the wobbly guide ?
The head was removed and shipped to Schumann Motor Works for guide replacement...and whatever else requires attention.
Chris Schumann ported the head and installed the valve guides for this build. He also worked on the bathtub head installed on my 82' motor.
BTW, another issue was revealed after the cylinder head was pulled...an issue with potential to do irreparable damage to the motor!
Notice anything unusual in the image below?

Re: Top-End Reassembly
27 Oct 2025 17:36 - 27 Oct 2025 18:22Is that mechanical lovemaking down to the worn guides?
Those were long-term relationships confined to the intake side, between all four lovers...
All that ended for good when the head came off, and they got caught!

Each piston sports a bigger pocket now...

Re: Top-End Reassembly
27 Oct 2025 17:58Whats the valve look like ?
I don't know. The head was shipped before I thought to check.
Likely escaped damage, judging by the lack of visible markings in the oily #3 combustion chamber image below:
