Thanks.
My experience was the same. I went to all the trouble to set the cylinder up in a press, heated the cylinder with a butane torch and the sleeves slid out with minimum pressure. Live and learn.

I'm about to press out a bad sleeve from my 305 and replace it with a sleeve from another 305. Aside from 'heat and press', any tips appreciated. Once the sleeve is pressed far enough out so that the lower section of the sleeve is flush with the cylinder's lower mating surface, is it necessary to us...

Perhaps others with more experience with 305s could opine on this. My first guess would be the carb, though. There...

Here's what we did on our Yamaha XS650 (750) race bikes, engines similar to the 305: To remove the top end without pulling the engine we cut screwdriver slots in the tops of the studs. With the studs out the top end could be removed without pulling the engine. In your case you'll have to double-nut ...

Transmission shafts fit fine, but final gearing of the two bikes is quite different, so a larger rear sprocket is needed.The CB gears with back-cut dogs and much better than the CA gears.

Good info, thanks. This particular CB engine had been sitting under the house for at least 20 years, and probably somewhere else before that. Plugs had also been removed. I spent a few weeks heating it and squirting various concoctions into the cylinders to no avail. After all the aggravation I had ...
