Hi all,
My clutch was a bit grabby when hot, so i removed it and cleaned and roughed up the friction plates and soaked them in 20w 50 oil.  I also wanted to drill extra holes in the clutch basket to improve oil flow but discovered that it has no circulation holes.  Perhaps only the later cb750's had pre-drilled holes from the factory?   Has anyone else done the 'hondaman' suggested mod and drilled holes in their clutch basket to improve performance?  I'm a bit reluctant to drill holes in an original part but will consider doing it if its a common modification.   It's a late model sandcast and a Sunday runner re  10068**.  Thanks.

Hello all.  I wanted to disassemble my rear shocks for cleaning.  This led to a discussion.  It looks like my shocks are from a K2 or later since no black tops -  my bike is late model sandcast Vin 10068**.   I note that Yamiya sell a black top replica set, but they also list a rear 'short type' replica shock for 1969 that's all chrome like mine.   Did 'short type' exist in 1969? There seems to be a variety of different rear shocks found on restored sandcast projects.  For ex., recent mag 'Classic Bike' Honda CB750 50 yr anniversary article shows a sandcast with rear shocks with no chrome cap over spring.  I read some of your previous threads on this.  Anyway, what do you think. Are 'short type' replica shocks merely for the modern day vertically challenged or were they an option back in the day?

I'm replacing fork seals which are weeping a bit. KO Vin 10068**
I read a warning by Hondaman in his book not to remove bottom fork allen bolts because of reassembly issues.  I'd like to clean up lower internals, but not sure if that's possible with KO forks?   Thanks. 

...still lookin for that bottom half of RH switch.  Any ideas or feedback would be great.

the top finish is beautiful but no way to polish out the bottom piece - i tried it on a buffer wheel.  It has a web like finish of rough metallic fragments in the anodized surface that can't be polished smooth.  - i'll send it back.

thanks,

Wondering about brake line reproductions for sandcast models post 2157.
The '88 differences' states that post 2158 fittings were long neck brake hose fittings, not short, - and that early sandcasts had upper brake hose steel neck fittings that were straight,1-2157 (late production has bend, like mine I guess- please see pic). 
I'd like to clean up my front hoses and fittings on 6806 and would really like to use KP's reproductions - would your lower hoses work for 6806?
I attached a couple of pics for reference.
