I like to call it "the little engine that could". It's got great power all around and when used with 30%fuel, proper clutch, plug, it's quite a show. It won't touch an NS12 or so, but people will be surprised you're running an MT12. What picco do you have? The .12Re versions do have more power than the Mugen and more top so I'd stick with that. The MT12 can be a back up...and if you do get it modified, it will bring out a lot more power.
