I saw this on the local Craigslist and it was worth a look. It followed me home and a new project begins. I enjoy the single cylinder Honda’s and couldn’t pass this up for the price.
1975 CB125S, the most interesting part is only 123 miles. I know it’s better to run an engine vs having it sit. Hopefully the fact it was stored indoors it’s life will go in my favor.
I have the carb off soaking and the gas tank off with some E85 gas in it. I have found that E85 will eat up varnish nicely. The tank had a small amount of varnish and appeared to have been stored fairly dry. The tank has a few small areas of what looks like flash rust in a few areas. I’m undecided if I will runas-is with an in-line fuel filter or trying something like Evaporust. If anyone has used something like that on a tank I’m curious of how it does long term.
It didn’t appear that anyone had messed with anything on the bike and the carb was virgin. The interesting part is the main jet is a 98 and idle jet is a 38. The Keyster carb kit I bought has a 38 idle jet but a 105 main jet. I may reuse the original main jet? If anyone knows anything about these bikes/carbs it’s a OEM Keihin stamped 660A.
The compression feels decent but I haven’t tested it yet.
I think some light cleaning, upto date maintenance, new tires, new gray cables and some grey shearing, and it should be good.
