Appropos of nothing, here's the CA95 I got running - yes, running...!

And yes, believe it or not it runs pretty well now. I'm trying to find the time to tweak it for my wife for springtime.

Nothing, yet - but I figure the odds are good that if I put that cylinder head back in As-Is, the cylinder skirt will heat up, expand, and probably snap right off and fall into the transmission.

Apparently I have what we call a 'work stoppage'. (sigh). At least until I can find another (affordable) lower cylinder head.

Blimey, I was disappointed when the engine I bought had a couple of rusty bearings and a patch of rust on one bore. You've certainly got a job on there.

Actually it wasn't that bad. It kept me off the streets, and I love bringing back neglected, unloved bikes.

But if you're talking about the red one above, that's running now, believe it or not! It took about a year, maybe 18 months, but it was a happy day when I rode it out of the garage and up and down the street. Re-did the seat myself and everything. It's not a show bike, but I just love hearing old engines run again after God knows how long. Yeah, rust doesn't scare me much anymore..:)


It's surprising powerful, too. I was only getting about 55-65 lbs compression out of it until I took it to my professional machinist; he just reground the valve seats and with new valves it now pulls over 150 per cylinder! I Did have to replace the cylinder head, though; as you can see in the pics it was pretty much toast.

Great job with the pictures!


For the cracked liner, get a replacement barrel. The fins can be dreadful.

Stand the barrel upside-down on blocks and hear=t with a blow torch. The liner will drop out. Swap the new liner(s) into your old barrel.....
