front sproket position and fit? <--- New question
« on: June 29, 2005, 06:18:31 PM »
I have the famous 1978 CB750K8. When I got it the front sproket was off. On one of the sides it is raised a bit. Does that raised side got twards or away from the case?

Don,

All the sprockets I have seen dont have a raised side, so you may have an aftermarket sprocket.
If you put it with the raised side away from the engine the chain will be a bit out of line.
Have the flat side face you then it should be the same alignment as the stock sprocket.

Good luck Don.

Is the sproket suppose to be tight against the shaft it goes on after you tighten the bolt and washer or will it move a little bit?

I bought a new bolt from honda but they didnt sell the washer(s) any more. Is the washer(s) just a plain flat washer or is it special in some way. All i got with my bike was the sprocket so i have notheing to go an.

How many washers are there?

I bought a SS washer that fits the bolt but when i tighten it down the sproket moves a little bit. Not front to back like the direction of the chain but side to side...just a little.

So in other words it is held in place but not tight.

Uh, just a thought, but maybe the raised part of the sprocket replaces the washer.  Is the sprocket OEM?

I have no Idea if it is OEM or not.

The bolt honda sold me is small and in no way could hold the sprocket without a waher of some osrt.

My K7 has the same setup.
Flat side of sprocket to engine.
Normal flat washer under the bolt. Use a bit of "Locktite" on the bolt.
The sprocket will move from side to side. This is adapted from trailbikes & allows the sprocket to find it's own place on the shaft depending on loading on the chain e.g. hard acceleration, slight mis-alignment of the rear wheel etc.
The setup looks flimsy but I've never heard of one coming off.
