Honda CB125T2 Restoration

I still use the similar engined ca125 rebel and 250 nighthawk as daily transport, appart from going over to electric starting, I wonder how different the engines are - they look pretty well the same. Great little engines, though mine have suffered from low compression after 15k and need a bit of work - never stopped them running, just loose power.

Unfortunately, the engine has still not been rebuilt as other projects have got in the way.

It would be good to get it done as I now have 6 bikes in the shed & not enough space to work out there unless I move 2 bikes outside. Not a good idea in the Winter weather.

If you havent rebuilt it i remember that the camchains, even though a duplex chain, used to get horrible tight spots so may be worth going a bit farther and changing that as well

My rebel has gone a bit sleepy on power and rattly on her original engine, reacon that could be camchain wear? I am planning to tear down the top end and at least re ring it as starting was getting a bit harder and sonic cleaning the carb and getting a more expirienced spanner man to do a service didn't regain the oomph. 31k on the clock. Funnily the replacement engine i fitted started to go the same way but came back to rude health after being laid up for 6 months and then only used occasionally for short trips. Very odd. Is 30k about the lifespan of these engines before a rebuild? History uncirtain but had regular oil changes and use for last 4 years.

Never saw one get that high as they were normally thrashed to death by little assholes

One problem with projects is how easily they're pushed to one side when other things pop along....like a grandaughter. This little wonder has made things difficult as she was born 5 weeks early, so the room in my daughter's house wasn't ready for the little one when she did go home.

Hopefully i'll find some spare cash at some time to finish off the CB125T2 project. It's that & the time that I need atm
