    Just a quick post. Trying to get some insight. Took off the valve covers on the 450. Inspecting Cams and Tappets. Does the lobe wear seem normal for a old 450? Also noticed the edges of the lobes are razor sharp. Is that normal?

    Hey all, I'm from British Columbia, Canada. I'm looking at possibly picking up a basket case 1982 nighthawk 450 as a first bike.

    Hi! I am a new user and this is my first post. Last summer I bought a "1982 Honda Hawk" from a guy in Montana. I had never heard of a "Hawk" but he assured me it was indeed a "Hawk 450" and not a "Night Hawk." He also assure me that it was road ready, so I drove 4 hours with my buddy to then...

    I just finished rebuilding the top end on my 72 CB450, new pistons, rings, gaskets, valves, sleeved cylinders, cams and cam followers repaired by Delta Cams. Bike fired up great, but I am now facing a carburetor issue. The idle is erratic, doesn't return to idle right away, after the bike...

    So I bought a 1982 CB450SC that ran like absolute garbage. One plug fouled out and the other insanely lean after a ride around the block.
