Partially Restored 74 CB550

<< < (14/45) > >>

I was being naughty and used the original tab washer when refitting starter gear to upper case. A tab snapped off when bending back into place so that was a timely warning. Have ordered a new one (90433283000) from DS but they are saying two weeks back order and I fear it could be worse. Anyone found a suitable off the shelf 6 mm tab washer to replace the oem washer ? I  have looked but can’t find anything….

Got a few of them lying around. I'll bung one in the post for you David.

Just something nagging me about that big spring, doesn't look right for some reason. Seems to be stretched out. So long as it works ok I suppose it doesn't matter.

Like the idea of the ziplock on the shaft to keep the washer in place, good idea.

Many thanks Ken that washer would be a big help. Part of the enjoyment of a restoration is getting to know your bike better and noodling on how little details work. I’ve never really looked into kickstarts before so I find this and our other discussions very interesting.

In other news I ve had to buy a replacement Mainshaft. There was a ridge on a  gear tooth that caused the gears to stick when rotating freely in neutral and I got the complete assy for £50 off eBay. Not sure if this was caused when the selector fork dropped out or by the gears being slightly misaligned when the cases were closed without  locating the bearing pin. Either way it wasn’t mr Hondas fault but the result of  poor engine building.

The amount of fine metal particles inside was horrendous. At one point the cam chain tensioner had dropped off and was found in the sump by the previous top end only rebuilder. He told me  bottom end was ok but shells were completely shot and bottom end gloopy bits in the casing plugs and end of main oil passageway were like grinding paste. Then he  misfitted the keeper plate for  the selector fork shaft so the gearbox  jammed completely after my first ride. It’s a story of real misadventure but nothing terminal and satisfying to get sorted with the help on here.

Just found this trawling the web.

Thought you'd like a laugh.

That’s horrible profiteering , add the postage and vat and you’re looking at 60 quid for a washer that cms had on sale for a couple of euros. I hope we can meet up some time so I can shake your hand and buy you a pint.
