pretty close to the discount $499 for the moto cult kit wouldn't you say.
Tinkering is still tinkering...but for the money I think I'd go a whole new engine.
There is pretty good chance the wiring will be plug to plug, if not shouldn't be hard to snip and crimp a solution.
The 5 speed 172fmm-3 non balanced engine is a bit cheaper but should be a direct bolt in swap for all CG/CB frame types.
My XL185 frame took a cg250 and a cb250 no issue with lower mounts...
on paper a standard cg250 is 10kw/14nm. the 172fmm-5 claims 14kw/18nm. So I would say there is a difference in power and torque.

Yeah, so $550 (shipped) for a 5 speed OHC non-balanced engine with a 3 phase stator that requires a new reg/rec and a new CDI as well. Does not directly bolt up and requires some fab work. Rated 19hp at the crank. which would be about 17-ish hp at the rear wheel. Unknown additional costs for wiring changes, CDI, etc.
$500 for a Motocult kit for a CG250. Doesn't need any fab work. Doesn't need any wiring or parts changes of any kind. Engine is already bolted in. Takes just a few hours to install taking your time with a cold beer in your hand, makes a proven 20+hp at the rear wheel.
Plus, you are trying to say "on paper" the STOCK CG already on our bikes makes less power (11.5kw tyvm) than the stock 172 engine when this entire thread is about installing an upgrade on a CG engine vs. Swapping the 172 engine in... Entirely counter to this entire thread, which is about an upgrade to a CG engine and your proposal is to swap the engine instead of upgrading it. Making that entire argument moot.
It's not cheaper. Not the same. Not even comparable. The cheapest engine option literally gives you nothing over the CG. Unbalanced and a 5 speed. All you get is OHC - wooptie doo
If I were going to go through all the work to put a different engine in I would at least get the 6 speed, and that costs even more, still down on power over the cheaper upgrade to the CG, and still much much more work.
Thus, we come full circle to - if I were going to go for a ZS172 engine I would simply get a bike that already comes with it.
