I'm not specifically familiar with the 250's however...

Likely if there's oil in the air box the oil level in the engine is way too high. Check the dipstick and see where it's at. If it is that high it's probably worth replacing the spark plug and cleaning the air filter as both will likely have gotten oil on them and may be causing further iissues.you may find oil weeping out other spots too.

I believe I have read that the "newer" 250's have a safety governor that isn't disableable as they're primarily marketed towards kids, so that may be the 25mph limit. Not sure exactly what year that started.
