Does anyone have a picture of the combuston chambers on the CB750K
« on: October 18, 2009, 02:11:17 PM »
Can someone either post a pic or shoot me a pic to my e-mail of the combustion(I don't think I spelled that right LOL) of a cb750K cylinder head?

ok,
                                 this is #4 cylinder on a 71 CB750k.
                 I put a 10mm wrench up next to it for a better idea of scale.
                        (right click and 'view image' for a bigger picture)
intake on the top



exhaust on the bottom.

that k8 chamber is a thing of beauty isnt it? very little shrouding around the valves.

Same size exhausts. Glass bead blasted. The K8 head is the 75/76 -392 head. HOWEVER it sure looks much better now that Wizard Rieck has done his 34mm magic to it.
