Topic: Front Sprocket Install

[pjandrew99]

I believe the statements below to be true but not sure. Appreciate the help!!!!

1- From the looks of the picture, PO installed the sprocket incorrectly since "hub" side should be toward the engine.
2- The locking washer has prongs that go into the "fixing plate". The others are tapped up to the sides of the nut to hold it into place.
3- Its worth saving a fully functional stock chain oiler by installing a somewhat expensive "rubber orifice".

Are those your statements or ?

Not sure what you mean by The "hub side" And "expensive orifice"
The teeth number, 18, usually faces out as it is in the picture.

Sprockets always used to have a "hub" both dides and i have never known one make a difference whichever way round fitted, no idea about tab washer and oiler, you can just screw the adjuster all the way in to stop flow

I read in a previous post that the "hub" side needs to go toward the engine. Wasn't sure what that meant so the clarification helps.
My chain oiler rubber is damaged and allowing oil to leak even when screwed all the way in. I'm debating on plugging it or replacing the rubber which is a pricey little part. The other alternatives I know of are the spark plug or the Joker plug. I'm not thrilled with either one of those. Thought someone was making some pretty nice plugs. PM'ed who I thought it was but haven't heard back yet.
My locking washer was not in the greatest shape but from what I can tell there are prongs that lock into the fixing plate leaving the remaining tabs to fold upward against the sides of the nut.

 I believe the original sprockets were double hubbed so they could be flipped over to wear the "other" side.

You’re remembering using a Honda CB650’s 530 single bolt front sprocket to convert 77/78 CB750F & K’s from 630 single bolt front 630 sprocket to 530 single bolt front sprocket. Where the 650 has the single shoulder running towards the inside.
It might be sb41 that posted the factory parts to make the conversion.  Not sure who…

Prior to 77 750s I agree Oem Honda fronts sprockets have shoulders on both sides.

May go the spark plug route to plug the chain oiler. Would a plug similar to the B5ES do the trick?
Thanks!
