| After installing
and honing the valveguides the next job was grinding the valveseats.
Aad has a really cool Hall valveseat grinder, made in 1943.
| We cut 3 angles in
each valveseat, all fits perfectly now! Check out some of the
movies below to see the cool old tools in action.
Honing the valveguides
Angling the grindstone
Grinding the valveseats
The heads were
masked off with Ducktape, glassbeaded and then very thouroughly
cleaned because that glass powder gets everywhere! Then valves,
collars and springs were installed after checking the free travel
and the travel to coilbind were ok for the .485" lift of
installed 4 new Bosch Platinum sparkplugs allthough the previous
ones were still working fine, those things last forever! The
old heads will be restored and put on another project, these
new heads can now be installed on my bike!
