A. information on guaranteeing one of the other cg or cb engine clones are a bolt in replacement is scarce. You will need your motor in hand and measure.
B. then you also need to acquire the pipe, carb, so on and so-forth. Which is not usually not worth the price on a $2k bike.

Then as i mention, you start realizing if your willing to do the mods for motor swap above, its not a far to stretch to mod a lightly used Japanese cruisers which can be had at similar prices.
Been down all of these paths.

Truth be told if looking to just maintain speed, turns out for me at least, decking the head was the least amount of time, work, money.
Got a video of it here. 5 minutes of my life.
Sounds strange now that i think about it, a simple head deck...
Best advise for newbies... All though I understand the challenge to improve/modify an existing machine.
A used Japanese 250 ( over 20 years with same engine) would be a better investment, for a commuter that needs to hold highway speeds.
If you were to bore the crankcase out 2mm... This big bore kit would make it a real "sleeper".
