Plenty... I hopped mine up with a big bore kit and hotter cams, 32mm amul carb... Went from 12.8hp up to 26 +/-... Fun bike, requires attention but not a difficult bike to work on and keep in tune. I sold it to my friend a few years back, he's thinking of selling it (around 2300 bucks, very reasonable with two seats and three exhausts), contact me if you are in chicagoland area. For your first bike, you might want to concentrate on riding though, something with decent brakes (it's got drums front and rear). I'd look into a new triumph bonneville or thruxton if you really like this kind of bike... Older style, but modern technology. But if you don't mind occasionally wrenching, the RE bullet is a fun bike... Good luck!
