kz750 5/8 offset bearing support ? was created by KZPens
Well I got done with the front and rearswap on my neverending project :unsure: , if I'm not out of time I'm out of money... :laugh: kzrider.com/index.php?option=com_kunena&...=11&id=154728#186083 , now I need to make a bearing support for the 5/8 offset sprocket, I think I'll use 1/2 inch 6061. Anybody got a source for a good bearing ? I believe it's 52mm od, and I was thinking on using a 4 bolt bearing flange and a piece of rod to connect the sprocket with the support, or should I get just a bearing holder machined to spec ?

Or am I overthinking it and should just cut off the lip of the sprocket... I'm tempted... :dry:

Any help / opinion appreciated

I have heard that you must use a bearing support with that large of an offset, but...........I am using a 5/8" offset sproket on my 750 and am not using a bearing support. To get the sprocket to fit under the cover i had the bearing support lip shaved off of the sprocket. I have put 100-200 miles on is all, but alot of those miles were ridden very harshly, and still no problems. I suppose it is very hard on the output shaft with no bearing support.

Yeah, I think I'll go through with making the support. I just want to ride it again, I'm riding my nake Goldwing GL1100 right now, and it's just not as much fun, maybe I'll try to trade it for a sportbike... btw. cool bike you have, love it.
