Honda-SOHC

Two things

(1) a large piece of plate glass from a glazing firm and some very fine compound will check if the case joints are flat

(2) Back when i did a lot of Ford engines if a big end knocked it was common practice for the rod end to need resizing as they ovaled

Boss decided to go out, part number 16013-393-004 in bubble wrap in a jiffy bag waiting your address, how about a fiver inc postage

I got some 550 K3 ones about and a lot of the parts are the same if you want to check it out and they are get back to me

If its the nipple warm the caliper not the nipple and use a long socket with T bar to get an even undo as they shear easy

Honda USA ones tend to be sealed beam which dip straight up and down not left or right, you may find the Cibie is directional so it wont pass. I find best aftermarket is a 7 inch unit from a car scrapper!!

But honda asked the dealers to remove them as they sounded too much like crossing beepers to the blind!!

carefull with ebay as the not so old 500 twin (and i dont mean the T) was also a cb 500 and a lot of sporty parts are made for those

Two things

bleed just the master first, i have put up a description on here before

With no front guard you need a fork brace or the forks will flex all over the place and handling will be crap
