Nick simply inserts a washer in his inlet to reduce the size down from 28mm to 15mm Then starts the car in ECU safe mode, its a bit juddery but 40 mpg no doubt!
there are a set number of bmx moves eg. flip and whip and x up. When you can do all three you can then learn flip whips, flip x ups, x up whips, whip to x up etc. Trials isnt like that so much, street riding is more though however.
If you spec the smokers package you get a large ashtray if you dont you only get a small one and a storage compartment next to it. You get a cig lighter no matter what to power sat nav/phone chargers. My dad had the 130D M sport modle.
