This model does not fit my K4....

Bert it doesn't fit because eBay says so, or because you know this? I don't trust eBay parts list, wrong 25% of time

bryanj · « **Reply #6 on:** August 12, 2023, 05:12:04 AM »

Ebay probaly says it doesnt fit because its not standard for a 750k4.
Why do you want an offset sprocket anyway?

It should fit all 750 from '69 to '78, what's different on yours?

Did you check JT Sprockets catalogue?

bert96 · « **Reply #12 on:** August 12, 2023, 10:27:31 AM »

Yes,i did. But they only have for the 750,900 and 1100f.

Do you need the bolt holes, because that looks like the splines of a 77-78 sprocket.

Yep, the bolt holes are different for k bikes.

enwri · « **Reply #15 on:** August 13, 2023, 10:15:22 AM »

77-78 don't need the retainer bolt holes. It's also a 630. non offset on a 25mm shaft.
cb750 k7

OK you're talking about the retainer holes not the splines.

Airborne 82nd · « **Reply #16 on:** August 13, 2023, 06:03:00 PM »

I think he needs the two extra holes for a 74. The 77-78 does not have or need them they use the large center bolt. The offset is the issue. How much offset? The 77-78 have a 10mm offset but it is on the rear sprocket carrier.
icbw but don't think so

Airborne 82nd · « **Reply #19 on:** August 13, 2023, 06:18:07 PM »

I know you said you found someone to make one. But could you explain what it is you are doing? Did you change something in the rear?

bert96 · « **Reply #20 on:** August 13, 2023, 06:26:09 PM »

New wheels,New swingarm New everything!

bert96 · « **Reply #21 on:** August 13, 2023, 06:51:30 PM »

No vibration at all!?!

"But you have a 750

"

Front sprocket for CB750K6 and older was held on with 2 bolts and a bracket.
Front sprocket for CB750K7 and K8 had 1 bolt in the center.
Boatloads of changes in 1977. Chain and rear sprocket are also not interchangable.
