like all engines that make big power they suck through petrol like crazy. Considering their small size they can make amazing amounts of power, and making this power is quite cheap too. They react very well to mods ie exhaust and plenum. The engine is lightweight and small so it can pretty much be put into anything. They sound tough
Maintanance is a hassle though, they inject oil and burn it to keep lubricated and should only use natural oil, never use synthetic on a rotary powered car.
