Lets build a SOHC for less than a grand
Erny:
Just to complete my experience from istalling tappered bearing kit on 750 K7 and 550 K1.
in both cases, I used All Balls kit 22-1011, content on the pic, including install instructions
Lower bearing - simply take OEM one, put it next to new tappered one and select proper wasther to have the same height. Don't remember which one I took, but it was exactly the same height finally than OEM.
Upper one - I used only seal and bearing w/o washer. Additionaly I grind off ridges from the spanner nut to ensure it sits flush.
This ensures that nut is turned enough to secure top.
Only outstanding issue is gap (appox 1-2mm) on top of ears - can be easily fixed by O-rings or custom made flat rubber washer or stainless steel washer(s).
note: photo of spanner nut after grinding is not mine (I forgot to take pics..) but looks like mine ;)

Yes that is the kit that I fitted. The lower bearing was a good fit but, the issue is the top cup and bearing. Even without the top seal and washer it was still too proud and not enough thread to safely secure the top nut. Even if you ground off the ridges of the spanner nut, that would only give you another quarter to half a turn more on the top nut.
As I have already explained that the only way, would be to mill out the seating area of the head stock about 3mm so that the cup sat lower. I have a old rotted out frame and will cut the head stock off and mill it, then refit this kit to see what results I can get. I will do this at a later date ;)

Got the tank back today, all filled and prep up ready for paint. Many thanks to the member who did the tank for me ;) [ Guests cannot view attachments ]

So, you didn't spot the CD250 new exhaust hanging beside it ;D
Will have to change the bars as those ones are a little low for a 550F tank and the throttle cable hits the tank on full lock. Need about another inch raise ;)
