Gear Lever Linkage Rose Joint possible alternative CB250RSA also 400/4 etc
AshimotoK0:
My 1980 CB250 RSA gear change linkage 'rose' joints were completely fooked and I am restoring this bike on a budget (albeit one which already totals to probably considerably more than it's worth ..but hey ho. ::)
Anyway I bought the parts below ... the cheapo rose joints were far to big so I chopped them to the correct length and trimmed down the diameter and profile of the round bit to be the same size as the Honda originals. I still need to tidy up the profile a bit and also zinc plate them ... I am thinking of two thin O-rings and a bolt and nut through the eyelet to seal the joint before plating. This is deffo one for home plating as I don't know of any commercial platers, who would entertain doing it.
The replacement boots look fairly decent and didn't tear on my test-out assembly, to ascertain if they are rubbish or not. Obviously, I will have to use a fixing for the normally peened over pin used on the lever parts but that's no big deal.

Good to see some progress Ash.
How many miles were on that gear lever assembly as a matter of interest?
