Assuming that you have a 2 stroke engine, all 2 stroke engines spit out some oil unless you are burning a full synthetic or synthetic blend oil that is designed to mix at a high ratio such as 80:1 or 100:1.
What you are experiencing is normal.
Note: never, EVER mix a low ratio pre mix oil at high ratios to overcome an oil spitting issue.
You will rob the engine's internals of proper lubrication and the engine will get ruined quickly.

Totally normal for a 2 stroke engine running standard 2 stroke oil at recommended ratios.
Those of us who use the more exotic 100:1 oils don't have the problem, at least to the extent that others do.
I'm not advocating the use of those oils, just stating a fact. Keep a few rags or paper towles handy to wipe off the residuals and enjoy your bikes. Glad your wife is sharing the hobby with you. That must be fun.

24:1 is an excellent break in ratio and will definitely drip.
If the oil you now use is designed to be mixed at 50:1 and you are happy with it then stay with it.
I forgot to mention that a carburetor that is tuned rich can also contribute to excessive oil dripping. That said, dripping is still normal, even at 50:1.
If you switch to Opti2 or a similar synthetic that is designed to be mixed at 100:1 you would be hard pressed to ever get any drips at all.
I solved my drippy problems on my 2 stroke bike by using an exhaust that goes all the way to the rear of the bike.

It can drip all it wants to now, I don't really care.

i had the same issue during the break in period, once i started to ride the bike more often and use the 1-25 ratio i had less problems, make no mistake though it will continue to happen unless you purchase a high syn oil which is much more pricy

Just make sure when you are messing with fuel to oil ratios and adjusting your carbs, you keep an eye on the plug.
